I have a Whirlpool GH6177XPS-0 G2 Microven and it stopped heating. At first it just took longer to heat up. Ran it two minutes and it did not heat up water or even warm it.

I ran it and listened to it and it made a faint clicking and buzz sound on and off every 3 seconds or so, like the magnetron was getting power. I am an electrician and I took the magnetron out. Magnets are not cracked no visible signs of failure. The contacts are not shorted to the metal frame and I have continuity between the contacts on the Magnetron. Could this be the problem or the Inverter board? Everything else works fine and no error codes.

[FONT=&quot]If your microwave looks and sounds normal but isn’t producing any heat, you should check the internal door switches, the high voltage circuitry and the circuit board for problems. You will need a certified technician to help you make these repairs.[/FONT][FONT=&quot][/FONT]

[FONT=&quot]If your microwave buzzes loudly and produces no heat you probably have a defective power diode (part # ) , magnetron (part # 8184139) or high voltage capacitor (part # 8184093 ). These are all things that can be replaced or repaired by a qualified technician.[/FONT]
