Happy Thanksgiving, everyone! What's better than having a dozen family members in for the holidays? Well, a dozen family members, a ton of leftovers, and no microwave, of course!

Anyway, this unit stopped heating a few months ago, and I bought a new magnetron, diode, and capacitor from APP. Installed the magnetron only, and the unit worked fine. Then the other day noticed it was running, sounded fine, but was not heating. So I took it out, and replaced the diode and capacitor with the part I bought. Also checked the magnetron with an ohmmeter, and it appears to be okay.

After we put it back together, the unit still did not heat right away. Tried for 1 minute on the express setting, then changed up the power level, but nothing. Then later, on a whim we tried a mug of water for 4 minutes, and it came to a boil. Thinking that maybe the microwave needed to run a while to charge the capacitor or something, we put it back in the cabinet, thinking it was fixed.

We were apparently wrong....still doesn't heat. Any ideas?

Thanks!

Hello, APP team. Will someone please address my question?

Thanks, Simon...but I got someone else at APP in response to my question on the parts page to say that "if the magnetron, diode, and capacitor are new, it must be the HV transformer." Could that be right? As I said above, the magnetron is less than 6 months old, bought from Appliance Parts Pros. Do we still think that it's the magnetron...whatever it is, I don't mind, just don't want to change out the wrong part. Thanks a million!

Hi, dear Tobomeo.

The suggestion to get another magnetron is my professional opinion.

Being a repairman for few years I've seen magnetrons going bad in several months after the replacement.

So, I still think that thew magnetron should be replaced.

Return the old one back under the warranty. Contact our customer service.

You are welcome.
