I also have a HotPoint (GE) Spacesaver Microwave Oven (MWO)that we got at Home Depot about 3 yrs ago. The magnetron quit yesterday and I found out online that this is a common occurance with GE MWO's. I found this string and thought I would attempt to have GE send me a magnetron to replace the defective original part.
I called Customer Relations (1 800-386-1215) and spoke with Nikita. I informed her nicely that I was aware that this is a common problem with GE MWO's and that I am a Union Electrician who would like to perform this repair myself. I simply needed the replacement part. She was very understanding and asked for the model and serial number and after a few minutes she supplied me with an order confirm #.
The part should arrive in a few days via FedEx and we will be back into space age cooking and also our appliances will still match. Thanks to all who posted to this string and clued me in (You have saved me a C note!).

SOURCE: MICROWAVE NOT HEATING ANYTHING?
If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.
Regarding parts, contact the seller here to purchase parts.
You can also order from MicrowaveSvc , they also provide parts.
