Microwave does not heat

I would suspect a door switch or door switch mount.

See my help file on door switches here:

The magnetron is the main part that gives out microwaves to heat the food. As the convection bit is working this points towards the microwave bits.
The magnetron has a main diode, fuse and transformer to run the microwave bit, any of these could be faulty. A word of warning though, there are extremely high voltages inside microwaves, even when unplugged in the main capacitor. Also to repair this section you will need to be a fully qualified engineer to even order parts for this.
Find a microwave technician who can repair for you

see this steps and fix it. God bless you

1. Check the power diodeThis electronic component is responsible for transmitting current in one direction. If the diode becomes defective it will cause your microwave to not heat. Test the diode and replace it if necessary.
   
2. High voltage capacitorResponsible for storing electricity, this part is a key component in any microwave. Remove, discharge, and test the capacitor to determine if it requires replacement.
   
3. Damaged magnetronResponsible for generating waves and producing heat. When your microwave is no longer heating properly, replacement will be required.
   
4. Thermal CutoffsExamine the thermal cutoffs on both the magnetron and the oven itself. Take off one of the leads and using a volt-ohm meter on RX1, check the terminals. If you get a result other than zero, replace the thermal cutoffs.
   

first suspect is the inverter board (power) and magnatron a distant second----in either case the part involved unless an expensive unit is pricey.

You have a failed membrane keypad.

On this model, GE doesn't make any parts available except the tray and the roller.

If it's in warranty, they will exchange or repair it.

It it's out of warranty, you're out of luck.

I'd advise you to contact GE Customer Service in case they may be able to help you.

hi,the magetron is what heats the food...it has gone bad...or you have a burn mark on the cavity were you ,put the food in to heat up....please check the cavity first...next it will need to replace the magetron...hope this helps....

don't know about the red light, but (fancy this) I had the same problem with my microwave tonight. Everything but heat worked. Unplug it, plug it back in. Worked for my GE Spacemaker.

hi mark,

actually, we didn't find any solution for the problem. we just bought a new one.

thanks,
cency

Start taking all screws out until you can access fuse.

Sounds like the keypad is okay, unless it might be intermittent.

Your wall voltage is within the proper range.

It sounds like it might be bad connections on the control board causing functional and display problems.

I work on control panels, actually, but I can't find any service data (yet?) on this model.

There should 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.

Did you find it?

Any chance you could scan and e-mail it to me?

Please feel free to contact me directly.
