The push button to open the door does not engage
in most cases this is due to a snapped of push bar as they are made of plastic its a common fault. if the push bar is not snapped then its lost a plug that holds it in. as the microwave holds a constant 1000 watts of power i always recommend to people to have them fixed by lic techs the repair cost for this fault is around $ 100 if the part is still available
hop this helps please rank advice below

The magnetron has failed and has damaged the waveguide. This type of failure is generally unrepairable. First look in your owners manual for specific warranties, then contact Whirlpool and explain to them what has happened.

No display on LCD panel on my whirlpool microwave
I do not know what procedure you used to replace the door, but if the buttons and display were working fine before you replaced the door then it seems that there is a plug not plugged into the control display panel. Other than that the low voltage power supply may not be providing the needed voltage for the display and only for the logic circuits which are a different voltage. With the microwave unplugged, take the cover off and look at all the connectors and make sure that they are plugged into something and none that are not plugged in. They should all go somewhere. To answer your original question, there is only one main fuse to the microwave. The circuitry in the control panel operates on low voltages +/- 5 volts or +/-12v so that part is not fused. What I recommend also is to go back mentally through the procedure you used to replace the door and that may give you a clue as to what you unplugged, although you should not have to unplug anything.

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.
