Question about Frigidaire GLMV168K Microwave Oven

1 Answer

Frigidaire microwave does not heat but will not shut off either.

Lights work but does not heat food. It will not stop running until I shut the breaker. Is this a simple problem that I can fix myself?

    it louder or quieter than usual?

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

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
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.

Frigidaire microwave electricity works because the lights and timers work but the microwave does not heat. need assistance


There are few parts that will cause this problem, the power diode, defective high voltage capacitor, or the magnetron that heats food is a common failure, and the least likely is the high voltage transformer that drives the magnetron. Parts and labor will run high depending on what needs to be done, I suggest appliance repairman to see it it can be repaired at a reasonable price.

Less than 5 years old - Microwave Panel lights up, turntable turns, fan works - everything works except it doesn't heat food. Heard a pop, and now it runs louder than before but doesn't heat. Any ideas?


That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.

Please rate my response if it was helpful to you.

Thanks, Repairman45.

Model FMT148G1B2 - over range microwave will not heat food. Clock, lights, rotating plate in M/W all work, just will not heat/warm.


well that depends on the current. If the current is a fluctuating type then microwave wouldn't heat or else if high...please check..

Constantly runs but does not heat


The circuit board is faulty. It should be covered under the warranty. Call GE or the place of purchase.

Everything works...Except for actually heating the food


It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.
