GE Microwave Not Heating Replace Magnetron WB27X11079

GE Microwave Won Heat High Voltage Diode WB27X10597

Microwave Diagnostic Has Power Not Heating GE General Electric Hotpoint...

There are other videos with possible causes and solutions on YouTube.

Many microwaves have similar issues. Usually, (not always) only the light is on and the fan is running, not the section that produces the microwaves. This problem can be caused by the door switches that are out of alignment or a defective control board.

Almost certain if microwave still heats a bad motor or gear issue inside the unit--if unit will not heat the safety switch in the side that the door engages is the cause of the wheel or platter not turning--prevents unit from use if door open.

It is good that the microwave does not work all together. It might be an interlock button or even a relay connection burn on the main mother circuit board.

Need a qualified technician. The service manual will be like $20-50.

Sounds like you lost your HV diode. Magnetron could be bad but these days they are pretty good. Diode costs about $5 at www.mcmelectronic.com . It is located in left side near the rear and should be straightforward replacement. Let me know how this works out. Thanks for using FixYa. Contact me if you need more info.

In microwave ovens, I have had the turn table motor unit become defective, or the power source to it has failed.

my microwave 1640GB from GE suddenly cannot heat food and make some noisy sound. as it is mounting in the closet, it is not easy to replace. any solutions or suggestion

Magnatron is suspect. Need to put a voltmeter on it and see if the input (primary) side to the high-voltage transformer (big heavy iron thing in there) is getting 120Vac. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing the magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"

Could you describe the noise?

It may be a noisy fan motor or a failing magnetron or high-voltage transformer.
