Question about Whirlpool GH7155XHS Microwave Oven
My Whirlpool microwave MagiCook 22C is not heating, it starts and everything is fine except heating. Can you help as the product is just 1 year old and very sparingly used, also company is not sending anyone for service.
Test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
The diode and capacitors can br tested. The capacitor must be alloweddischarge before testing, or you risk to get electrocuted, even ifpower is off. Capacitors can get discharged by shorting their twocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
