Question about Kenmore 62702 Microwave Oven
I was using my Kenmore above the stove microwave and it made a loud pop, sounded like a gunshot. Now everything seems to be working the same, except it does not heat. Do I need to just replace it?
Probably a high voltage diode popped because contaminated grease eventually built up and made a path for a high voltsge arc to occur.. To confirm,take the outer cover off the microwave and discharge the high voltage capacitor by shorting its terminals. Then pull the plug off the magnetron side and place it near the magnetron socket. Now turn the microwave on and push the connector on the magnetron with a chopstick or a long insulated screwdriver. If no arc when you do this this confirms a bad diode.
please rate my suggestion..

Welcome to FixYa
The loud pop
sound is caused when either it is a bad fuse or the high voltage capacitor itself
has gone bad and needs replacement. As everything is working fine so the
problem seems to be either with the door switch or the high voltage capacitor
that is bad. Please check the door switch if that appears to be fine then to
replace the high voltage capacitor you'll have to take it apart completely. Please
get back to me if you have any other questions.
