The unit warms and cooks your food. And so your KitchenAid microwave door sensor not working isn’t a good gesture. With the error, you are not going to use your microwave. Good enough that you can fix that or get someone to do it. Stay here
5 Reasons Why Is Your Microwave Door Sensor Not Working
Here are five causes you should take note of!
- Broken sensor parts
When you open the microwave door, the bulb and halogen light indicates that the sensor is working. These two function closely. If the bulb isn’t lighting, it could be it blew off, or the sensor broke down. Whatever the issue, you must test the bulb to see if it works.
It isn’t easy to test the bulb when it is in the interior of your microwave. At least, not by looking at the bulb! So you have to access it and remove it for testing.
It may sound like a long and tedious process, but you have limited options. Besides, repairing a door sensor is much more complex and costly. So be patient and remove your bulb as follows:
- Shut off the microwave power source and unplug your microwave.
- Locate your microwave vent and remove the panel. That’s easy by unscrewing.
- Look out for the case containing the halogen bulb.
- Remove the cover and unscrew the halogen bulb.
- Test the bulb with a voltmeter. First, set the voltmeter into ohms, then place one wire on the button of your bulb. Check the readings. Your bulb is dead if the gadget doesn’t read zero or the arrow isn’t close to zero.
- Install a new bulb.
- Check if the new light works. If not, you may have to investigate further. Your microwave may be having multiple issues.
Installing a new bulb will allow you to troubleshoot your door sensor further. Also, a functional bulb gives you the green light on what to do next.
The source of power comes from the socket. When the socket is not working, your microwave sensor will also not function. You must also determine the power output at the wall source.
Low voltage in your microwave may not work, including the sensor. The voltmeter will test the socket and allow you to move to the next possible cause. If the voltage is low, it could be a power issue that is affecting the entire house.
You may proceed to test an adjacent socket to rule out that. If the other socket is working, shift your microwave there as you make arrangements for a replacement. Never plug your appliance into a faulty socket that will require a replacement.
- Wiring/Electric Circuit
An incomplete circuit will not allow the passage of current. Several things will cause the short circuit. One of those is a broken wire. That could be on the power cable or inside your microwave.
Any short-circuiting wires in your machine will blow a fuse and damage several other functions in your oven. That includes the sensor. Your oven’s sensor is electric and therefore requires a complete flow of current.
You can have an electrician rectify the wiring. If the external cable is faulty, you can replace it at the nearby electrical hardware store. Keep inspecting your device’s cord to straighten possible twists.
- Control Board
Electrical appliances have control panels, which center all the functionalities. A faulty control board is possible when your microwave’s door sensor isn’t working. The board is in the microwave’s interior, so you must access it for inspection. First, disconnect the power by unplugging your device. Your second step will be checking for continuity.
Use a voltmeter to ensure the control board has the correct voltage to run all functionalities. Also, measure the voltage transfer to your door sensor.
An electrician can identify the terminals for different functions, including the door sensor. Ask him to determine loose connections between the control unit and the door sensor. Some damages may be beyond repairs. If so, opt for a replacement.
- Dirt or dust
Build-up dust on the sensors can make them not function well. That also includes grime and other sticky substances. The buildup causes obstructions such that your door sensor cannot work. When the sensor fails, your microwave cannot heat, cook or rotate your food.
Remove all the obstructions and dirt by conducting a deep cleaning on your microwave. You do not need to scrub, as a soft piece of cloth will do magic. The cleaning should be a daily exercise to prevent build-up.
KitchenAid Microwave Door Latch Problems
A latch helps you fasten your microwave door without struggle. Several problems can occur, leading to latch failure. But one crucial point is that a latch error will not allow your microwave to run. You want to explore more on the causes, so keep reading!
Worn out latch
Door latches wear out with time. After prolonged use of your microwave, the latch might develop issues and stop functioning. It doesn’t have to be extended service as the latch can break. That happens when you bang on the door repeatedly.
Rough actions on your microwave door wear or breaks the door, so it may never close. When the latch is broken or worn out, you can only replace it to get it back to its functionality. So ring the experts to assist.
The hook helps the latch to lock correctly. In most microwave ovens, the door hook consists of rigid plastic material. Though strong, the feature can easily break. Due to breakage, the releasing and opening of the door becomes a nightmare. When handling your microwave, be gentle.
Banging the door can cause breakage. Door hooks are available in most repair shops. The match will depend on your brand and model. Sometimes, replacements aren’t available, and you might take home a counterfeit.
Take utmost care of your microwave to prevent breakages. You may never get the original components for replacement.
The spring is a unique component of your microwave door. It assists in closing and opening the door smoothly. But to function, it must not be overstretched or too tight.
Overstretching or failure to stretch is a major fault in springs. The hitch will cause difficulties in opening and closing the door. An expert can help check the spring for any damage and amend it. The spring rusts at times, making it break or fail to work.
Sliding Arm Lever
Your microwave’s sliding aim lever activates the door switch. Also, closing and opening your microwave is not easy if the lever breaks. And so is the door latch.
Confirm that the open sliding arm lever is free from any damage—the only option for a broken arm lever is to replace it. Leave the job to experts before you damage the door component further.
Microwave Keeps Saying Open And Close Door
The door of a microwave is either open or closed. There must be an error when the microwave keeps saying “open and close.” We will want to eliminate this error by looking at the causes and solutions below:
- Blocking Materials
Remove or eliminate anything that blocks your door lock. After purchasing your microwave oven, it is easy to forget to take off all the packaging from the microwave. The material around the door will interfere with the closure of the door.
Never use your microwave with the packaging material still on the surface. Cleaning is crucial as it allows you time to remove the cello tapes, cling films, and styrofoam from your oven. Countercheck and remove to clear the error.
- Door Closure
An error will occur as a result of improper closure of the door. It has happened severally to me when I close appliances absent-mindedly. That tends to happen when I am multi-tasking.
Other times, it is out of ignorance. If you haven’t gone through your new appliance’s user manual, you will find yourself doing things wrong.
When closing the door, ensure there is a clicking sound. That’s a confirmation that the door is firm. If there is no sound, open and then close properly. Be sure not to bang your microwave door to avoid breakages.
- Door Switch
Another cause for the open and close error is a defective door switch. The switch signals to the control board that the door is closing.
An improper contact will send an error. And so, you will see the open and close error. Open your machine’s door and close it to ensure proper connection.
There are occasions whereby the switch can be faulty. You need to check its status. If you aren’t sure how to inspect, request a technician to do the assessment.
A loose or faulty door latch will not close the door firmly. That happens due to a damaged latch or a wrong replacement.
If you suspect an open-door latch, look for a replacement. Or, if you recently replaced the component, but it has the same hitch, get a good fit for the door for replacement.
A visit to your dealer with the gadget can help solve this puzzle. Latches play a significant role in closing and opening microwave doors. Maintain and replace them frequently to minimize the error ultimately.
- Microwave Position
All cooking appliances must lie flat on a firm surface. That balances the microwave so place it on a flat surface area. An inclined surface may cause the door not to close.
Your Kitchen Aid microwave will display the open and close error. That is intentional to alert you that the machine isn’t stable.
A flat level area enhances proper closure and opening of the door at specific, regular, and recommendable angles. With this in mind, there will be no risk of any error. Always keep in mind the position and placement of your microwave.
- Ventilation Area
A microwave works best in an area with good ventilation. Remember to switch on the exhaust of your microwave. The feature acts as a vent to eliminate moisture during cooking. It does so to prevent moisture buildup.
If you aren’t aware, water damages the metallic parts of your appliance. The wetness is a recipe for rust, so your door parts may rot with time. Eventually, your machine will display an open and close error. So, keep your microwave free from moisture by activating the exhaust. Also, keep your kitchen well-aerated.
- Metal Use
Using utensils that have metallic accessories causes a high risk to your microwave. Metals lead to arcing during heating in the microwave, thus causing door damage and errors. That damage can be costly for you to amend.
Always avoid using metals in your microwave. Or, upgrade to microwaves that do not have metal issues. To know more about metallic accessories used in your microwave, refer to our previous guide.
The guide, Why Doesn’t The Metal Rack In Microwave Spark, answers all your questions on metal use and safety in microwaves.
- High temperature
Electrical gadgets are not heat-friendly. The heat affects various functionalities, including the sensors and the control panel. You might ask how because the oven is a heating appliance.
Here’s the answer. Although the microwave itself produces heat, there is an insulator that safeguards sensitive functions. Excess heat from the power source (voltage) can overpower the insulator. As your gadget overheats, your microwave will register errors.
Too much heat weakens your microwave with time, rendering it faulty. Once it is defective, it will also display errors. Ensure that you have a professional to help you measure the voltage and get the correct components for replacement when necessary.
- Proper Maintenance
Handling your microwave with utmost care is crucial. Press the switches and latches gently. Also, when cleaning, uses a soft sponge and do not scrub your machine. Using steel wool also damages sensitive components.
Replace any breakages immediately after they happen. And as we said earlier, apply less force when closing your microwave door not to cause any damage that will lead to error.
Clean your microwave regularly, especially after use. Never clean your appliance when it is still on the power source.
Periodic cleaning leads to dust and grime accumulation. The much might be causing the open and close error. Take caution by switching off your microwave before you start cleaning for safety purposes.
KitchenAid Microwave Door Switch Problems:
The switch, latch, and sensor are all complex parts of your KitchenAid microwave door. As a significant component, your oven cannot function without a door.
Mostly, your microwave will not turn on whenever the door switch has problems. Also, the situation can worsen if the door does not open or shut. Your biggest worry is your gadget cannot heat, reheat, or bake.
The fault will make you suspend all your cooking process or throw your leftovers if there is no reheating alternative. Get down to the reason for your door switch issues. After that, we will capture the steps for fixing the component.
Reason for Microwave Door Switch Problems:
- Loose Circuit
The wires feed all your microwave’s electric parts with power. And so, when there is a loose or detached wire terminal, the switch won’t work. You can determine the disconnect by routing the wires to the control. If the cords aren’t intact, then work on them.
- Dead Switches
The microwave door switches may have hit their end of life. Only a multimeter can determine whether the buttons are dead or alive.
To find out, you must access the three switches that lock your door; the primary, secondary, and monitor, following that sequence. The three switches keep your oven from cooking with an open door. To test the components for continuity, follow these steps.
- Set your multimeter readings to OHMS.
- Open the door to test the primary and secondary switches.
- Start with the primary switch by placing the multimeter on the connectors. Open the door while testing. If there is a beep, the primary button is working.
- Test the other switch (secondary)following the same steps.
- Move to the monitor switch. Test it while with a closed door closed. Open the door while testing. If there is a beep, the monitor switch is working.
Now you know whether the switches are working. If not, you have to access, remove, and replace them.
Follow the below steps to fix/replace the switches:
- Switch off the power or disconnect your microwave from the power source to avoid shocks and electrocutions. Remember that health and safety come first in all your processes.
- Take off your microwave from the cabinet. Once you open the microwave door, remove the turntable and all other parts from inside the microwave. If it is a built-in appliance, you will have to begin removing the trim kit. Follow the proper process so as not to damage your installations. Or, call an expert to do it for you.
- You can use a screwdriver to gently take out all the screws for mounting brackets and place your microwave on a flat surface area. I prefer a free countertop space.
- Locate your microwave’s rivets. Remove those that hold the panels of the microwave together with the use of a screwdriver.
- Dismantle the left and top panels of the microwave to locate the door switches quickly.
- Disattach the door switches. Remove the tabs that lock the features together.
- Please take note of the connecting wires and master their connection before you disconnect them from the door switches. You can also take a photo for reference if you forget when reconnecting them.
- Get a new set of door switches that is compatible with your microwave model. First, connect the wires to the door switch as you refer to your photo for a perfect connection.
- Return the switch to its housing after confirming that the wires are in place per the previous connection.
- Assemble both panels while screwing them correctly, each in its proper place. Once done, return the microwave to the cabinet.
- Ensure that you mount your microwave well by use of mounting brackets and position it well in the cabinet. Then return the turntable as it was.
- Switch on the power and test the functionality of the new door switch.
Ouch! It was a dozen-long process, but you did it. Congratulations!
KitchenAid Microwave Display Says Door
The best thing about KitchenAid microwaves is the display that signals you when all is not well. You will get errors such as Door, Open and Close, and more. It is imperative to check your door when the display shows an error, more so Door.
Be glad that your microwave can sense something is wrong with the door. Mainly, the signals save your appliance from extensive damage. So, if you are in distress and do not know what might be the problem, check out below:
- Door Closure For Long Hours
Modern microwaves have more fantastic features. For instance, your appliance will warn you when you close your microwave for more than 5 minutes without instructions. The display will indicate a door error.
Already, the device has responded by not starting without instructions. But again, the system is lenient in reminding you that you haven’t started cooking. To clear this display, open the microwave and close it before you start using it.
- Door Lock
The signal may also indicate a non-locking door. Always check for anything that may be blocking the door lock or door latch. An oversize dish in your microwave can hinder the door from closing correctly.
When the cooking rack is in the wrong position, the door will not close. After shipping your microwave, confirm that you remove all packing materials from your appliance.
Check on the manual all the materials that are not part of the packaging. Also, those that are not necessary for your microwave’s performance. Rip them off and clean your oven before use.
- Location And Position Of The Microwave
Ensure that the cabinet where you place your microwave gives a flat level/space without any obstruction. If your appliance hangs or lies on a sloppy surface, the door may not attach well. It will register a Door error on display. Also, closing and opening the door is not strenuous when the surface is flat.
- Contact Area
Ensure the door’s contact area is free from dust or dirt. A layer of sticky substances on the door makes the door not close tightly. Have a schedule for cleaning or wiping the contact areas more often.
- Close The Door Entirely
A slight microwave door opening will signal that the appliance is open. It doesn’t matter the closure angle. If your microwave is advanced, its display will indicate Door and not run.
Order-generation microwaves do not display Door, but your microwave won’t run until you correct the error. Confirm that the door is firm and tight. Do not apply too much force or bang, but push it gently until you hear a clicking sound.
KitchenAid Microwave Door Latch Pushed In
The reasons for door latch push-in are as follows:
- Door switch failure
When the switch for the door fails to work or works intermittently, the latch pushes in. Check the three buttons independently to determine which one has a malfunction due to overheating. We have highlighted the processes for checking the three sets of switches and how to fix them.
Test the thermo-protector for continuity of voltage. It protects the microwave from overheating. When there is too much voltage, the Thermo-protector trips, and the microwave stops working, which may lead the latch to push in.
- Door banging
When you heavily bang the door, the latch pushes in. In the process of banging, there can be a lot of damage to the door contact and the microwave.
Although fixing the above latch issues depends on the cause, the process may be long for you. So, follow the below steps to resolve the issue.
- Unplug Your Machine
You must be sure that the microwave isn’t in the outlet. That reduces the chances of electric accidents.
- Access The Plastic Panel
The panel is on the interior part of your door. Open your KitchenAid microwave door and inspect the inside. You will get hold of a seam that’s around the interior plastic panel. That is, inside of your door frame.
- Separate The Plastic Panel And The Door Frame
Unscrew the panel and slide a narrow-edged screwdriver or knife into the visible seam. Move the blade around the door and pop the plastic board. That detaches the panel from the metal door interior.
- Remove Your Door Latch
The door latch is at the edge of your oven’s door frame. It has a plastic component with a long chunk of plastic. Locate the hooks and lift them out of the doorcase. Remove the spring at the bottom of the door.
- Inspect The Latch components
Sometimes, the latch may not be faulty. The spring you removed in (4) above may have slipped off or broken, leaving the latch with the inability to hold and release your door.
Examine for rusts too. If the spring is not hooking up to your door’s metal frame, it needs a fix or a replacement. Check other broken parts and determine if you will replace the entire latch. A professional can examine and resolve the error for you.
KitchenAid Microwave Door Not Closing
Your microwave door, not closing, can hinder you from your cooking activities. Maybe the door broke, or there are obstructions. But let’s determine further;
- Faulty door
A faulty door interferes with closing and latching. It also means the contact area for your microwave door is defective and won’t allow closing. Prolonged usage and wear and tear can result in errors in your oven’s door closure. Get technical personnel to repair it. If it has tears, seek a replacement.
- Door blockage
Any kind of blockage on your microwave door will prevent closing. It could be a hanging cloth from above, an extra large bowl, or an oversized turkey in your oven. An obstruction on your door’s contact area will hinder the door activities. Ensure you keep the contact area free from any blockage.
- Cooking rack
Does your microwave have accessories like racks and mats? Fit them appropriately. A tilted position of the cooking rack in the microwave will prevent the door from closing.
Ensure that it is put into place and fits well. If your frame isn’t holding well, you probably replaced it with the wrong model. Get a rack that is compatible with your KitchenAid microwave. You can also learn how to place the cooking rack correctly from your user manual.
- Cooking Utensils
Incompatible and oversize utensils cannot allow the door to close firmly. Also, placing them will lead to protrusion and blockage.
Oblong-shaped plates that are also large will rotate in half and begin blocking your entry. So your choice of utensils must be microwave friendly and the correct size.
- Shipping Materials
Some materials pack your microwave when shipping. These materials, when not taken off properly, can block the door. To ensure that the door closes tightly, remove them entirely from the contact area of the door.
KitchenAid Microwave Door Open Button Replacement
Any microwave is useful when the buttons are not defective. We use buttons on the gadget to set time, reset(soft or hard), pause, cook, close, open, etc.
You will find the open button necessary as it salvages the situation when some controls on the appliance fail to function. An example is a reset, canceling a program, etc.
Because of the KitchenAid microwave’s programming nature, it is the only button canceling/off. You can also use the button to clear errors on your display. When the open button can’t work, you are in a muck. The internal components might be broken, including the actuator, spring, lever, latch, and hook. Talk to your tech. A replacement is better than repairs.
KitchenAid Microwave Door Won’t Open
Below are some of the reasons why the door will not open:
- Broken door hooks
The hooks and the latch engage the door to close it. So if it broke while closing, it wouldn’t release the door open. The cause for breakage could be regular wear or banging on the door. The repair clinic will check and replace the hooks for you.
- Defective door latch
The microwave door is difficult to open if the latch is defective. Repairs for this component aren’t possible, so seek a replacement.
- Door spring
A broken or rusty door spring causes a stuck door. You cannot open the door freely. Get a spring replacement from a center near you.
- Open Lever
Inspect the open lever for damage. If there is a breakage, the only remedy is to replace it.
- Defective door button
A defective door can shut your door altogether. That means it has a broken internal component. Replace the button to solve the issue.
- Faulty handle actuator
The actuator connects the door button and latches. It makes opening easy. Accessing the oven can be impossible if the actuator breaks while closing the door. Switch off the gadget and try to pull the door out gently. Or, call the experts for detailed guidance.
- Detached Button Spring
The button spring is different from the door spring. You will find the small spring attached to the open button. If it loses its grip, the door may not open.
You have to access the open button and secure it properly. Or, if it is a breakage issue, get a replacement from the repair clinic.
