This is almost certainly a blown high voltage diode.

Micro wave not heating


It sounds like a failing magnetron. Sometimes they can be intermittent before they finally fail for good.

Chances are your oven has a 5-10 year warranty on the magnetron.

Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

To allow us to help you effectively (at no charge), please post a
NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, and your detailed symptoms.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

Microwave popped and now does not heat


Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

My goldstar above the stove microwave popped and now won't heat. Everything else on the unit still works. Is this a problem that can be repaired? Thanks.


Did it make a loud pop like a firecracker?
Sounds like the High Voltage Diode shorted out and it probably is making a low or loud growling noise now..... ???
