GE Spacemaker Problem

Could be the magnetron or the transformer. No it is not worth repai

Suspect inverter (power) and or the Magnatron---neither are cheap parts.

You might want to do a search using that part number to see if you can find it cheaper. Sears is a little high on things like that.

It is the magnetron circuit that has failed. It the part that generates the microwaves that heat the food. If it is making a loud buzzing sound when you try heating something, then the magnetron is shorted out. The replacement cost for the magnetron is almost as much as an new oven, so it does not make sense to have it fixed. Sorry.

If it stops heating and the other parts of the oven still work, the problem is with the magnetron circuit. If it makes a loud buzzing noise when you try to heat the food, then the magnetron has shorted out. The replacement cost for the magnetron is almost as much as a new oven, so it does not make sense to have it fixed. Sorry.

Sounds like the magnetron just shorted out. Its the part the generates the microwaves that heat the food. Buzzing sounds are a symptom of a shorted mag. Usually not worth fixing since the magnetron costs almost as much as a new oven. Sorry.

Hi


Thanks for using FixYa. If it’s a loud hum/buzz sound then 90% it’s usually a bad magnetron and other times it’s a bad high voltage diode. However, from what you have described it seems to be the magnetron. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

HI, the loud popping noise was the Magnetron tube. this is the main heating device. the noise filter is also damaged and, should be replaced as well.

In conclusion, replacing the Magnetron tube and noise filter will fix this unit.

please dont forget to rate me on this issue...

It's very likely the high voltage transformer or the magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Some manufacturers will send you the magnetron to do it yourself. If nothing else, you can save about $75 by taking it to the shop yourself.

Here are some links you or a friend can use for test help, but read the safety warnings first:

You can usually find helpful exploded view diagrams and order parts by entering your full model number 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.
