Hello there:
If it It sounds normal,and seems to run ok but there's no heat When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the megatron or power inverter or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician. ok hope this helps best regards mike

My 10 year old GE Spacemaker XL1400 microwave has stopped heating the microwave's contents.


probably a magnatron failure
take it to an appliance repair shop for a proper diagnosis and get a quote as repairs can be more expensive than new unit

I was heating my tea and I heard a loud pop and the unit turned off...I thought I had blown a fuse and went out and checked fuse box..flipped all fuses and microwave still not turning on at all...micorwave...


The description you provide indicates the magnetron has failed, "heats food" and blown the main fuse in the microwave oven, since the unit is 10 years old it is much cheaper to replace with a new one rather than have it repaired.

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

Sparks are coming from the bottom of the microwave


generally the microwave will only spark if there is metal on the container you are cooking with or you are operating it without anything in it. as it is that old and with all the advances they have made with microwave ovens ... if it is in the budget i would certainly suggest getting a new one

Turns on but not heating food sounds a bit louder


Hi, this is common in most microwaves. this abnormal noise is coming from a faulty Magnetron. this device is responsible for the heating process and, it is damaged and not heating at all at this point.Simply replace the Magnetron and, this unit will start to heat once more.

Microwave won't heat anything


Yeah, it's time to invest in a new oven. The magnetron tube in yours most likely just finally wore out. It's the source of the microwaves, and like any tube it gets weaker with age and finally just quits altogether. It would cost more for a new magnetron than it would for a new oven these days.

Microwave lights and buttons work but doesn't heat up anything


When you start the microwave say for 1 minute. Listen closely when you hit start, the light should come on and about a 1/2 second later you should hear a little click and a slight hum. This means the controller is turning on the high voltage transformer and that part of it is working. My guess is that the magnatron is bad. That's the most common problems with all brands of microwaves. The mat on the top should not have caused the problem since the microwave has heat shutdowns in it. I would say that it's a 90% chance it's the magnatron. Most microwaves have a 5 year warranty on that part. Look at your owners manual. Good luck.
