This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

My whirlpool micro- combo intermittently won't start ??


Take a look at the hinge. You may need to shim it up a bit or replace the pivot or make a bushing if it is worn. There is an interlock that will prevent operation without the door closed. Check that to make sure it is properly engaged.

My whirlpool microwave/oven combo is displaying a "DOOR" error message, and the microwave won't work. I have replaced a 20a bus fuse and all 3 door micro switches... It is still displaying the "DOOR"


When microwaves first got popular I used to be a helper with my next door neighbor who fixed them. I does sound like you should have covered it with those switches. If you close the door very slowly, pulling back on the door see if you can hear all 3 switches clicking. You should be able to hear them easily. If you only hear the first 2 try pushing on the door to hear the 3rd. If it will click with pressure on the corners or in the middle then you door is tweaked, possibly from pulling on the door hard to open it or smacking into something on the edge. If you can hear all 3 switches and it still wont start then its going to be the sensor that receives the signal from the switches. I'm not sure how accessible those are on today's models since they make them as disposables now, back then they cost around $500 so they were serviced.

GE spacemaker microwave turns off during cooking and display goes black


Step 1:


Door Switch




If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board




If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.


Touchpad and Control Panel




If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad




If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer




If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat




If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

see this causes and fix it .God bless you
f the microwave will not work at all, make sure power is on at the outlet and test the electrical cord. Test the fuse and replace it if it is faulty. Also check the door to make sure it closes properly. Test and, if needed, replace the fan. If the oven doesn't cook or cooks only intermittently but the display is on, check the door interlock switch, the thermal cutout (see the Applaince Controls Fix-It Guide), and the fan, replacing parts that don't pass the test.
If the oven keeps blowing fuses, check for a faulty door interlock or monitor switch.

I replaced a cracked door on my Whirlpool microwave MH1150XMQ2 and now it wont work. The light stays on and I can enter info into the display, but the unit wont turn on.


The door is not adjusted correctly.
The micro switches in the cabinet are not making contact.
Radjust the door hinge until the switches are made correctly by the latches on the door.

Display has a f2 code on it. whirlpool oven is model mh1150xm and less than 3 years old.


determined from whirlpool that the f2 display is from the control circuit board. the board's problem is intermittent and needs eventually replacing. not covered by warranty. determined that whirlpool has reduced the warranty for the electronic circuits in its appliances from 5 to 1 year. this is great for consumer confidence in whirlpool. have had trouble with 2 other new whirlpool appliances. probably will not buy another whirlpool appliance.
