SOURCE: Microwave won't heat

The two possible causes are a faulty door switch and a bad magnatron. You can pull the top cover off of the unit and check all of the door switches (there are 2-6 of them all on a common rail, me normally closed)). If the door switches all check out, replace the magnatron, diodesmag-glass_10x10.gif, and capacitor

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).

SOURCE: Kenmore built in microwave displaying "D" and wont heat.

"d" may mean demo mode. The first thing to try is a "hard reset". Unplug it from the power outlet for 10 minutes, plug it back in, set the clock, then try again.

SOURCE: microwave stopped heating

I had the same oven for one and a half years and had the same problem. Had the sears repairman come out and he said the magnetron burned out and needed replacing for $285. It was never under warranty with the warranty that came with oven. I couldn't believe it! We had an independent repairman look at it and he found a design flaw that causes the magnetron to blow. If you replace the matnetron (megnatron?) it will work for awhile, maybe, but then just need to be replaced again. It's cheaper to buy a new microwave. In fact, I got out our old microwave that's over 20 yrs. old and still works--just isn't as fast and as new ovens. Good luck!

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man.
Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Have Kenmore microvave and the vent starts on its own


Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.

Kenmore microwave 721 85032010 will turn on but won't heat or spin


Chances are that is just a defective top or bottom door switch or its mount.
See our help file on door switches here.
Also, that model number does not show up as a valid US Kenmore model.
Please check the tag in the cooking cavity or elsewhere n the oven and let us know if you need further help.

Kenmore 665.61629100 Microwave Problem


The 665 prefix on your model number is Whirlpool, but I haven't found the code "d" listed yet.

Can you set the cooking time?

If so, what happens when you press Start?

I'll post back if I find the codes or if you have other info and I can help further.
