Whirlpool otr microwave

The screw might be hitting a live wire in the wall which is very dangerous! Make sure there are no live wires where the mounting goes.

cabinet out of alignment , if this is over the range adjust the way you have hung it, the pawls on the door are not contacting the switch in the unit

I would unplug the oven for 2 minutes to do a hard reset and try it again, just in cause there was a glitch.

Without knowing your full model number from the tag on the oven, I would wonder if it has a separate internal cooling fan from the hood vent exhaust fan. It could be an unrelated issue.

For more free DIY and other help & advice, feel free to contact me with your full model number and FCC ID number from the tag on your oven.

Remove cabinet cover and observe what's going on.

this is usually a bad turn table motor. if you remove the screws out of the bottom of the otr(over the range) it will hinge down and back and you will see the motor in the middle of the otr. your local parts house should have this item in stock or be able to order it for you

This fan motor is feed from a sub mini relay on the main pcb {control board}

I called a technician out today. Seems like the problem is the circuit board. It wasn't working properly and the sound is the fan. The fan is supposed to turn on when the microwave is in use and off when it is not. In this case, the fan continued even when the microwave was not in operation. A new circuit board has been ordered and will replace the old one when it arrives. For now, I can still use the microwave, but I have to unplug it everytime I finish heating something up. A little inconvenient, but at least it'll still heat my food up in the meantime.

Yeah, that's fan which stuck in "on" state. However the root cause is in a control board.

FIRST ,,MICROWAVE OVENS ARE REALLY SAFTY MINDED AND THATS A GOOD THING....THERE ARE USUALLY THREE DOOR SWITHCES NEXT THE KEYBOARD--THE ONE ON TOP AND THE ONE ON BOTTOM ARE PRIMARY AND SECONDARY SWITCHES,,YOUR PROBLEM SOUNDS LIKE ONE OF THESE IS NOT MAKING CONNECTION..YOU MIGHT BE ABLE TO PRESS 'DOWN" WITH A LITTLE PRESSURE ON THE DOOR AFTER CLOSING TO SEE IF THE FAN WILL START,,,IF YOU NOTICE --THERE ARE 2 LATCHES(HOOKS) COMING OUT OF THE DOOR,,WHEN THE DOOR IS CLOSED,THOSE LATCHES ARE SPRING LOADED AND MAKE CONTACT ON THOSE SAFTY SWITCHES....THIS IS NOT A CUSTOMER REPAIR--MICRO'S ARE JUST TO DANGEROUS WHEN YOU TAKE THE COVER OFF--IF THIS DOES BRING THE FAN BACK ON--YOU GOT A BAD DOOR SWITCH AND SHOULD BE A REASONABLE REPAIR
THE OTHER SOLUTION STILL WOULD BE A CONNECTION PROBLEM ON THE KEYBOARD ITSELF-THE WIRES JUST PLUG ON THE CIRCUIT BOARD BEHIND THE KEYBOARD---STILL A EASY REPAIR--GOOD LUCK TUNICA
