Kenmore Microwave not heating. Turns on, lights, clock, etc.

SOURCE: GE less than 2 year old microwave runs, doesn't heat

The problem you are having is that the magnetron that actually does the heating has gone bad. The fact that everthing works fine rules out any type of bad fuse since there is only one 15amp ceramic fuse in most cases in the unit itself. The magnetron is located behind the control panel on top and has some cooling fins on it. Replacing it if you are a do-it-yourselfer is pretty easy provided you can find one at local electronic supplier or on the internet such as www.mwoparts.com if you would like to see what it looks like. It is held in place with typically 4 screws. It has two to three terminals depending on make and model and age. With everything unplugged it comes off easily enough with no desoldering or soldering to do. There is a High Voltage Capacitor and Diode that could be bad also, but without being able to check it in person it would be difficult for me to tell that they are. In my experience the magnetron is the first thing I replace and have never replaced a capacitor or high voltage diode in the past 20 years. Good luck and God bless.

SOURCE: no heat in microwave

Test the high voltage capacitor, the rectifier diode.or the magnetron.

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 the same problem with my microwave, the clock disappears and it says "enter" and "amt", I figured out it's the "beverage" button that is sticking. When I want to use it I just press "beverage" and then "reset" and just press them over and over until it stops. Usually it's on the first try, sometimes I have to press them a few times. Just don't do what I'm about to type though, I decided to get my razor knife and cut the button out carefully, I only cut the contacts on each side of the button, now no buttons work, I should have left it the way it was, at least I could use it that way.

SOURCE: No heating, turntable does not turn, but clock & lights work.

Check to make sure the plastic on the shelve holders or tuntable guide did not wear and expose metal. If these holders or brackets are wore and exposed metal it shorted out your micro wave. They need to be replaced and a fuse needs to be replaced inside the control panel,
