Microvave stops heating

Microwave Repair
1

Everything “seems” fine - lights and features all work.
Here are the symptoms: [LIST]

  • When the system is turned on, it makes a louder humming noise than normal and then it stops heating after about 2 - 3 minutes. The system still continues to run, just no hum and no heating.
  • When making popcorn, I noticed that the steam produced stays in the chamber and does not get expelled.[/LIST]Any suggestions?

TIA,
Mark

sounds like a bad capacitor/diode.

Would that also explain the lack of venting inside the chamber? Or, do I have a fan problem too? :confused:

The steam inside the oven may point to a bad fan. This may be what caused the microwave to malfunction.
