How do I fix a microwave that does not heat up items?
The microwave makes a loud buzzing noise and does not heat the item up. There is an odor when it is running. The ordor is like you smell when a electical appliance burns out. The control panel, lights, and turn table are working.

The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

Microwave not heating


It most likely is either a issue with the inverter (power supply) or the Magnatron (main unit) in this oven.

It could be a thermal fuse inside but the noise sounds more like Inverter or Magnatron.

If not a cheap unit have a shop take a look and get an estimate.

Microwave makes a loud buzzing noise and emits a burning plastic smell


This indicates the magnetron has failed, buzzing sound and odor are classic symptoms. It is cheaper to replace than have it repaired.

Started flashing and making popping noises, but still heated ok. Then stopprdheating and just makes a loud buzzing noise


The magnetron is most likely the problem, it heats the food and is the heart of the of the microwave oven, if it was followed by unusual odor more noticeable when you open the door that would confirm it, but that is not always the case. The cost to repair would exceed the cost of a new one

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Microwave won't heat, light ,clock works the microwave just won't heat the items in it.


hELLO THERE
when a microwave quits heating but every thing else is ok normally
investigate these 4 areas

Investigate these three areas if your microwave won't heat but you hear a loud buzzing or humming noise:
microwave_diode.jpg Power Diode

A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat and you will hear a buzzing noise. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.

picturena.gif High Voltage Capacitor

A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating but you are hearing a buzzing or humming noise. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.

microwave_magnetron.jpg Magnetron

A defective magnetron is the third possible cause of why your microwave is not heating, but you can hear a buzzing noise. Test your microwave's magnetron. Replace it if it is defective.

Microwave comes on but not heat item


It's most likely the magnetron that has failed if it does not heat the food. The magnetron is the part the generates the microwaves. When it fails, it typically shorts out, and makes a loud hum or buzzing noise. If this is the case, it is not worth fixing since the cost of the magnetron is almost as much as getting a new oven. Sorry.
