My GE microwave is making a loud humming sound it seams to

This answer was rated:

My GE microwave is making a loud humming sound it seams to be running slower and it's not heating up or cooking anything.

Justin :

The most common and probable problem you're having is due to a failed magnetron. GE spacemakers are famous for failing magnetrons.

JACUSTOMER-0j5xcucb- :

Is this something that i can replace myself?

Justin :

You're capable, yes. It's not typically something I'd recommend a customer do themselves though. It requires pulling the microwave down and removing a lot of screws. I would like you to check your manual though because, depending on the age, the magnetron may be covered. It's an expensive part.

JACUSTOMER-0j5xcucb- :

Ours is about 6 years old. How expensive?

Justin :

I'll need your model number. It's probably on a tag inside the cavity on the left side.

JACUSTOMER-0j5xcucb- :

I need to go downstairs to get it. Be right back.

Justin :

Ok

Justin :

Ok, give me a minute or so.

JACUSTOMER-0j5xcucb- :

No problem

Justin :

WB27X10017 is the part number. It lists for 130 bucks. The manual states your magnetron is covered 5 years. With the loud humming sound and the fact it won't heat, there is a 99% chance it's bad. A bad magnetron can cause the high voltage diode to go bad too, but not usually.

Justin :

You can buy a new microwave for twice the price of that magnetron. It's usually not worth it unless the mag is covered.

JACUSTOMER-0j5xcucb- :

That just answered what I was typing!!!!

Justin :

I have ESP apparently lol

JACUSTOMER-0j5xcucb- :

Thank you and we will look into the price of a new microwave. You have been very helpful!

Justin :

You're welcome. Have a nice holiday.

JACUSTOMER-0j5xcucb- :

You too!

Justin :
