Question about Frigidaire FGMV174K Microwave Oven

1 Answer

My microwave is making a very loud noise and not heating food.

Everything works correctly except for the noise and not heating of food. Microwave is only 2 years old. I read different tips on diagnosing and fixing it. I have replaced the magnetron and the capacitor with no success. I inspected the switch for the door and I think its okay because the light comes on when its open or when the microwave is on. Also the turntable and the microwave run when the door is closed. Thank you for any help with this.

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.

SOURCE: Microwave turntable doesn't turn. Everything else

The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You can find links to helpful exploded view diagrams and part ordering help here.

But if you've recently had trouble with the cooktop lights, then the control board may be damaged.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

SOURCE: My Frigidaire microwave is less than a year old.

The symptoms of loud noise and no heat indicate a short in the magnetron or high voltage diode. Need to take it to a qualified repair, to figure out what the problem. The magnetron replacement can cost as much as a new oven. See what the warranty covers, maybe you might luck out.

SOURCE: I have a Frgidaire microwave

The unit normally draws about 13 amps of current when it's running, so it's not unusual for the wires to get warm.

A bad bottom door switch is very common in these units.

Once it's fixed, make sure no one opens the door while it's cooking. That causes premature switch failure.

Tell them to hit the "stop" pad first.

Microwave made a loud grinding noise while heating a cup of coffee for 1 minute,now everything is shut off. We checked the curcit breakers all ok, and there is power going to it!


see this causes and fix it. God bless you
Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

Exhaust Fan Motor If the microwave is loud when running the fan motor might be

Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Everything works except the cooking part/no heating/turntable not turning, help!


you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt
