Unless an expensive unit replacing the Magnatron and or Inverter that powers the unit will cost more than replacing the unit itself.

Electrolux microwave buzzes and food doesn't heat up


If the unit operates correctly except heating the food, then the unit needs a new magnetron.

Microwave light comes on and turntable revolves when food is put in, but it doesn't heat food up. Food remains cold, can you help? thanks Dee


9 times out of ten it is the magnatron that has gone bad, that is the device that creates the microwaves for heating the food. Check inside the cabinet for fuses and if none found or blown then it is the magnatron. These are available widespread but most cost about as much as a new oven, so do a google search on your make and model of microwave and search for a magnatron for that unit. This will bring up parts suppliers and their prices and you can decide if it is worth fixing or replacing

The microwave no longer heats food and it smells as if something is burning. Everything else on the microwave works. Is this a common problem and how can I fix it?


Its your Magnatron tube, thats what makes the microwaves and heats the food. The part will cost you more than a new micro. The new model that replaced yours is a JVM1540 and you can get them for 179.00

My GE spacemaker II microwave won't heat what can I do


Hi,
The main internal component of your microwave oven is called a magnatron. This is the device which generates the microwaves that heat your food up. If your oven appears to be working properly but it's not heating the food, it means the magnatron is not generating microwaves. It could be faulty itself or it could be a component linked to the magnatron. (high voltage capacitor) etc.
Have this component checked by a qualified technician.
Let me know if I can be of any further assistance.
Best wishes,
Graemevm

Spacemaker XL1800 runs but doesn't heat.


I think you should check the fuse first that runs the magnatron if the fuse is good that means the magnatron is bad! but if its only the fuse then you save time and money!

HI. I have a Whirlpool Microwave (MH6141XKB). It will not reheat the food and makes a louder "humming" sound than normal. Other than that, everything works fine. Please advise. Brent


Brent
The magnatron in your oven has gone out and will need replaced!( This is the device that heats up your food) If everything is working and your food is not getting hot 99.9 percent of the time its the Magnatron or its fuse! The loud humming is also a big clue the MAGNATRON has gone bad!

This is due to the magnatron failing (this is the part of oven that cooks the food!) This is the most likely cause of y isssour oven not heating the food!

THE MICROWAVE DOESN'T HEAT UP?


Is the unit under warranty? If not, you can try to remove the cover and see if there is a blown fuse in the section that powers the Magnetron. How old is the unit? Typically, no heating of food, indicates a bad Magnetron (tube).

Good Luck,
