For this kind of problem, most likely, your microwave has a bad magnetron.

If you have a knowledge in electronics, you may open your microwave (if it's already out of warranty), and check for any busted fuse. But if you could not find any busted fuse, contact the manufacturer for second opinion.

But as I mentioned, the possible cause of this problem is bad magnetron.

Let me know if you have any questions.

Thank you!

My microwave GE model # JVM1440WH04 spacemaker has no heat coming out of it. My husband heated microwave lasagna in it last, everything works except for the heat, any solutions?


Push the microwave door tightly closed. The computer will not start cooking until the door is closed for safety reasons. Some models of microwave will give a warning on the screen if the door is open.
2

Ensure you have programmed a heat setting, entered a cooking time and pressed the "Start" button on the microwave's keypad. Check that the microwave is not set to "Defrost" mode.
3

Unplug the microwave and wait for one minute. This measure will reset the microwave's internal computer if it has frozen or scrambled. Plug the microwave back in and try again.
4

Ensure the keypad lock mode is inactive. Most microwave ovens have a lockout feature that prevents children from starting the microwave while unsupervised. Lockout mode is usually deactivated by holding down the button that bears a padlock symbol

Microwave oven does not heat


When you press start the light and cooling fan are ON but the Microwave Oven is not heating then the magnetron must have failed. If it is out of warranty it is probably better to buy a new microwave oven.

I have the same problem. Everything seems to work except it doesn't heat up food.
I remember last time when it was working. I pressed the start botton before I closed the door. So it didn't start automatically, and I pushed start and it worked(it still heat up the food), but it doesn't work now. Help Please!!!
I have a Whirlpool Gold GH5184XPQ.

Thanks in advance

Microwave fuses down when I press start to heat


are you saying the unit go's dead if thats the case there is internal protection shutting it down and some troubleshooting would be required to figure out what is causing it.

Turns on by itself and turntable does not rotate


You may have a control board issue. Thank God for safety switches.
This is a problem that an integrated circuit tech. can repair, but it may be costly.
Decide how much you want to put into this oven vs. buying a new one.

Contact me once you decide and I can help you find a service center.

Thank you,
