Question about Frigidaire FMT144G1 Microwave Oven
Everything was working fine, tried to heat food in afternoon, unit sound changed to buzz sound everything else works but it will not heat food.
The most likely problem is the magnetron. Check your warranty in owners manual, I believe you have five year warranty on magnetron.

est 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.

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.

HI, you will need to replace the heating device. This device is called the Magnetron and, it will cost you about $133.00. This is a repairable issue but, you will need to call for service. I do not recommend installing this device if you are not familiar with handling this type of tech.

SOURCE: Food won't heat up
Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...

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.
