Microwave won't heat

Okay, we have the same problem as a few of your other posters. The microwave won't heat...it is 7 years old. Old, yes, but used 3 times a week at best. I know your previous responses mentioned something about the door switch. My my microwave seems to make a little different sound. At first, it sounds normal, but within a few seconds, it sounds like the fan has come on. Regardless...still no heat.

Thoughts?

Thanks1!

    The light and turntable come on.

    Sorry, don't have a way to post a video with sound.

    Model number is GLMV168K131.



    Thanks

    Do the inside light and turntable come on when you try to cook?

    Can you post a video with sound?

    Do you have the model number?

I got a goldstar microwave in April of this year (2008). It did not
work, I took it back and they gave me another one. After four
months it does not work and I'm very dissatified with this product. I will never buy a goldstar product again.

Then I would suspect one of these problems:

- loose or corroded connection at the magnetron
- bad magnetron
- shorted high voltage diode

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

At our site, we now have a video available showing how to remove a typical control panel assembly in under 5 minutes.

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
