I see. Okay, well then I would expect there's a problem with a high voltage part, such as the diode, magnetron or transformer.

Your model number should be entered as JVM192002 and you can find exploded views here.

You can usually find GE parts for much less here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

Likely takes a torx wrench or some other special star tool to open it.

Could be a bad relay a bad mag tube or a bad timmer or a bad door switch. Needs to be trouble shooted. You have to get it open and check the fuses and test the voltage on the pri transformer first.

This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

There will be a reset switch button on your microwave's timer or somewhere on the appliance. Try the button and if it doesnt work then call customer care. It seems like a minor problem and can be fixed quickly..

My convection microwave will not heat up in convection mode. the microwave function works just fine. is there a way to troubleshoot and repair the problem?



    usually if convection fails means there is problem in magnetron you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. This is not easily fixed; contact a service technician.
please do rate me on the above said issue

Smeg fmc24x oven and grill work turntable and microwave dont


I have a simular model and I found that the circuit board has three black relays, one for the grill one for the convection and one for the microwave. I found that the microwave one wasnt working so by swaping the microwave one with the convection one I got it to work and then replaced the faulty one with a new one at a later date.

Convection oven problem


Most of the time the magnetron is defective if the food is not heating up.
In some cases there is a defective low power transformer or other componenents associated with the magnetron.
I would suggest to check the owners manual under the warranty section. Sometimes the magnetron has 5 years warranty.
Good Luck.
