Microwave won't heat food

No heat at all

    I have the same issue.



    It failed for a moment a few days ago, but I hit 'Clear' and restarted and it worked. Now it doesn't work again and nothing seems to get it to cook again.



    Using any of the cooking modes (Express, Time Cook, Defrost, etc.) starts the clock to countdown but the unit doesn't heat the food (and no 'microwave cooking sound') nor does the turntable spin/turn.



    All other functions work fine.

If the microwave operates normally, but does not heath at all, then it can be 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, your model number did not return any result, contact the seller here to purchase parts. (here in UK).

9 out of 10 times if all else is working then it is the magnatron rod that does the heating chances are it will be more expensive than to purchase a new microwave.

If it has a platter does it turn? (possible safety switch in the door issue) Other than that a Diode, inverter board (diode might be on it) or the Magnetron bad.

I have a Haier microwave and tonight after heating some food, I went to close the door and upon closing it, the carousel started turning and it won't shut off.


It sounds like one of the door switches has become defective, each must be disconnected on the one side and tested with a digital meter using the ohms scale.

Problem with the GE Spacemaker (JVM1640SJ) Microwave Oven GE Spacemaker XL1800 won't heat food anymore....It worked this morning, now won't heat. What should I do?


GE Will replace the magnetron for 9 years! Mine is a 2004 model with a one year warrently according to manual. HOWEVER they did say the magnatron was covered for nine years: call 888-239-6832. When I called they said thats all they get calls for and would send out in 3-5 days. NO CHARGE. I had to ask if there was coverage longer than a year on major parts and that's when they offered the info and I eventually was transferred to the right office. Saved $120 bucks on parts alone.
