The most common reason for a whirlpool microwave door sensor not working is a faulty door switch. To fix this issue, the door switch will need to be replaced.
If you rely on your microwave to make quick and easy meals, a malfunctioning door sensor can be frustrating. If your whirlpool microwave door sensor isn’t working, it’s likely that the door switch needs to be replaced. The door switch is an important safety feature that prevents the microwave from operating unless the door is closed properly.
When the switch is faulty, the microwave may not turn on, turn off randomly during cooking, or fail to shut off at all. In this article, we’ll discuss how to diagnose and fix a faulty door switch to get your microwave back in working order.
Signs Of A Faulty Door Sensor
If you rely on your whirlpool microwave every day to prepare your meals, you may suddenly find it unwilling to cooperate. There could be many reasons why your whirlpool microwave won’t start, but one of the most common causes is a faulty door sensor.
In this section, we’ll go over the most common signs that your door sensor is malfunctioning and how to address the problem.
The Microwave Won’T Start Or Turn On
One obvious sign of a faulty door sensor is that the microwave won’t start or turn on at all. This indicates that the sensor isn’t detecting that the door is closed, which means that the microwave won’t function until the problem is fixed.
- The door switch is damaged or broken.
- The door latch is misaligned or not functioning properly.
- The sensor or actuator is not working properly due to dirty contacts or wear and tear.
The Microwave Starts But Shuts Off Without Finishing The Cycle
Another indication that your microwave’s door sensor is not working is if the microwave starts but shuts off without finishing the cooking cycle. If a faulty sensor doesn’t recognize that the door is closed and sends the wrong signals to the control board, the microwave might stop working partway through the cycle.
- The control board is malfunctioning or detecting the wrong signals.
- The door latch is not engaging properly, and the doors aren’t entirely closed.
- The microwave door sensor is detecting an obstruction, so it shuts off immediately to prevent any further operation.
The Interior Light Stays On Even When The Door Is Closed
Another clear sign of faulty door sensors is when the interior light stays on even when the door is shut. Typically, the light should only come on when you open the door and turn off when you close it. This problem may cause your microwave not to turn on because the door switches are meant to cut power to the lamp and other functions when the door is closed.
- The switch contacts are dirty or faulty.
- The actuator is not pushing the door switch far enough.
- The switch housing or assembly is worn out, misaligned, or broken.
When your whirlpool microwave door sensor is not working, it disrupts your routine and makes cooking more difficult. Most door sensor problems can be solved by cleaning or replacing the sensors. It’s essential to turn off the power and unplug the unit before attempting any repairs. Any repairs should be made by a qualified technician to avoid the risk of electric shock.
How To Check The Door Sensor
Microwaves are among the kitchen’s most used appliances. They’re great for heating up food and cooking meals in minutes. That’s why it can be frustrating when your whirlpool microwave door sensor stops working. When this happens, your microwave won’t start, and it’s time to start troubleshooting.
In this article, we’ll discuss how to check the door sensor for signs of damage or wear and what to do when you detect them.
Unplug The Microwave Before Checking The Door Sensor
Before you begin inspecting the door sensor, you must unplug the microwave.
- Locate the plug and pull it out of the wall socket.
- Alternatively, switch off the circuit breaker that controls the kitchen’s electrical power.
By following these steps, you’ll avoid getting an electric shock when inspecting the door sensor.
Locate The Door Sensor And Inspect It For Signs Of Damage Or Wear
The door sensor is often located in the top corner of the microwave’s door opening.
- Open the microwave door and locate the door sensor.
- Check the door sensor’s plastic housing for signs of wear or damage, such as cracks or discoloration.
- Inspect the sensor’s prongs and clean them with a soft cloth if they’re dirty or dusty.
If you notice any visible signs of wear or damage, you might need to replace the door sensor entirely.
Use A Multimeter To Check The Door Sensor For Continuity
One way to check the door sensor is to use a multimeter.
- Set the multimeter to the continuity setting.
- Touch the two multimeter probes on the door sensor’s prongs.
- If the multimeter displays a reading of zero or near-zero, the door sensor is working correctly.
- If the multimeter displays a reading of infinity or a value above zero, the door sensor is faulty.
If the door sensor doesn’t read a continuity value of zero or near-zero, you should replace the sensor.
Replace The Door Sensor If Necessary
If you’ve detected that your door sensor has signs of wear or damage, or it fails to display a proper continuity value, you need to replace it.
- Purchase a replacement door sensor that’s compatible with your whirlpool microwave model.
- Unplug your microwave from the wall socket.
- Remove the screws that attach the door sensor to the microwave’s control panel.
- Disconnect the old sensor’s wires, and connect those from the new sensor to the microwave control panel.
- Reattach the microwave control panel and screw it back in place.
- Plug the microwave back into the wall socket and test the new door sensor to ensure it’s working correctly.
By following these simple steps, you can check if your whirlpool microwave door sensor is working correctly or not. If it isn’t, you can solve the issue by replacing the door sensor. Always ensure the microwave is unplugged before inspecting or replacing the door sensor to avoid any accidental electric shocks.
