Whirlpool Microwave Ovens - Recent Questions, Troubleshooting & Support
I have a whirlpool over the range microwave with an F6 error. Model # MH7140XFB-1 Serial # XCL1222267 I can't shut the door or it just continues to hum. How can I fix this?
Open the oven door. b) Unplug the microwave oven for 2-seconds and plug it back in. ... The sears manual refers to F6 error as a F6 -Microwave Relay Failure, which would explain why the motor is "humming" The relay is part of the PCB and may require you to get a new PCB
The F6 error indicates a relay on the control has failed.
You can try to unplug the microwave for a few minutes and then try it again. If the error repeats then the control will have to be replaced.
Microwaves are not good do-it-yourself projects and I recommend a technician check and repair this problem.
Microwaves are inherently dangerous to service. Internal capacitors can retain a lethal electrical charge even when the microwave is unplugged. A microwave radiation leakage test must be performed on the unit following any repair.
I recommend calling a service technician to repair this type of problem.
