GE spacesaver xl1800 microwave. Unit comes on, but no heating

Is this an over the stove type unit? I have had a few problems with my over the range spacesaver. I think the heat from cooking gets up into the microwave and damages it. The steam from me boiling things on the stove had mine quit heating and I purchased a new one. The parts to replace the faulty ones can be quite expensive over $150.00, so its better to purchase a new microwave.

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

sometimes... you can repair it by your self. but before the magnetron. try to check the high voltage fuse and the high voltage capacitor... ty

F3 means that a contact is shorted on the control panel. Replacement contact panel required I think.

ITS MAY BE HIGH VOLTAGE SIDE PROBLEM. DIODE OR CAPACITOR

open door to unit get model number and got o searspartsdirect.com and enter it in to get part number and prices...... or shop locally,, also repair clinic.com also sells parts and shows pictures of most hope this helps let me know

There are some troubleshooting steps you can take to possibly determine the problem before calling or taking it for service, you need a multimeter and a capacitor discharging tool. if you posses BOTH of these tools,
there are 4 causes for this symptom
1) Transformer
2) Capacitor
3) Diode
4) Magnetron
I can instruct you on how to test and/or replace the first three of these. The magnetron is VERY dangerous and should not be serviced or tampered with except by qualified personel. let me know if you would like to take any of these steps otherwise you could bring it to a repair station.
Hope this helps...Feedback always helps me

ckeck the membrane key pad.

call a pro. these units run at a deadly high voltage. simply not worth your life!

I don't like to pass on your problem but it sounds very much like either the high voltage supply ot the magnetron has bit the dust.
Either one would make the repair marginal at best.

This is apparently not a very good unit, many microwaves jsut kind of fade away as their magnetron emissions decay.

This one seems to have a bad rep. look at this link:

Sorry, have owned a lemon or two myself.
