Question about Kenmore 62702 Microwave Oven

Microwave made loud popping sound and now does not heat.

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?

Hey,
Try this
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..

My kenmore over stove microwave oven is now LOUD and not heating when on. What's up with that?


The problem is in the magnetron or the inverter board, either part will be costly.

I have a microwave that is not working, I started it and a loud pop and smell happened. Everything is still working, the lights, the motor, the clock, the ventahood, but doesn't cook anymore.


Hello & 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.

Well I'm reaching here---if the bulb did not fracture/break then it sounds like a capacitor popped--check your owners manual for reset button but I don't think there is one for the lighting---In addition if you can see the circuit board--look for burn spot or wet spot. GL

My goldstar above the stove microwave popped and now won't heat. Everything else on the unit still works. Is this a problem that can be repaired? Thanks.


Did it make a loud pop like a firecracker?
Sounds like the High Voltage Diode shorted out and it probably is making a low or loud growling noise now..... ???

Lost heat on microwave ,everything else works fine simple fix?


Inexpensive fix yes, but quite dangerous as you have to either replace the High voltage Diode or the magnetron depending on what has gone. Most often it is the Diode as that is fed a few thousand volts and anomolies such as a surge in current cause it to blow(popping sound) You can also check the fuses and if lucky it is just a fuse, but a fuse very seldomly just blows as it points to an underlying fault such as magnetron , capacitor or Diode. Have a service man attend to it unless you know what you are doing as you are dealing with lethal voltages and current even after the microwave has been switched off.

Everything works except the cooking part/no heating/turntable not turning, help!


you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

Microwave made a loud pop,won't heat,sounds like it's only on half power, makes a low intermittent hum


This is almost certainly a blown high voltage diode.

Kenmore Microwave Hood Combination: over the stove Model #721.80602500


Disclaimer: I'm a DIYer, not a technician.

Our GE over-the-range microwave stopped producing heat yesterday while warming part of the T-giving feast. Everything else (fan, control panel, light) works fine.

After disassembly and testing last night, I discovered a defective "secondary door switch." Your Kenmore uses a similar switch (~$19 on-line), and that might be the problem. But it also could be other things, such as a bad thermal cut-out.

If you know anyone who's handy with a multimeter, most of the basic diagnostics seem to be pretty straightforward.
