SOURCE: 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.

Test the high voltage capacitor, the rectifier diode.or the magnetron. If all this are fine, test the control board.

If it additionally does not spin and no light, then check also the door switch and fuse.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts. (here in UK).

I have a Russell Hobbs RHM2018 microwave oven with grill and the turntable will not stop going round and the light stays on until I unplug it? Once plugged back in it carries on in the same way? If I


The switch for the turntable does not disengage anymore. Could be a relais, could be an electronic switch. When opening the door, a second switch, in series with the other one, connected to the turntable motor disengages, stopping the motor. The light is switched on, because you opened the microwave. Perhaps you never noticed this, but it is the normal way that should work.

Food not getting heated


There are three common issues, magnetron "heats food" cracked high voltage diode, or a shorted high voltage capacitor. In order to find out you will need a professional to assess, it will be probably cheaper to replace the microwave oven.

Microwave Quit Heating


The Magnotron goes out on many of the lower priced models in the first yr.,(and some of the higher end ones too!) As the components there do most of the hard work. Better to just find a recycler who takes them and scrap it.
As for the replacement that sounds like an excellent idea!

Microwave seems to work but doesn't heat up


HI, when the Magnetron becomes unstable, the microwave will not heat anything. simply replace the Magnetron. This device creates the heating action and it is damaged and not functional at this time.
