    Why is my Whirlpool AVM542 Microwave Oven running but not heating food?
    • R
      Richard CastilloAug 3, 2025
      If your Whirlpool Microwave Oven seems to be running but not cooking food, several components could be defective. It could be a defective magnetron (filament broken or shorted to ground), a broken ground wire on the HV transformer, or a filament wire shorted to ground or broken. Other potential issues include bad contact in the magnetron terminals, defective control boards, or a breakdown of the HV diode, which may also produce a humming noise.
