Common Symptoms

  • Microwave produces no heat
  • Microwave heats inconsistently
  • Microwave makes unusual noise while operating

Check Before Replacing

  • If the microwave operates but produces no heat, the diode may be one possible cause; also consider the magnetron, capacitor, and related high-voltage components.
  • Do not access or test the high-voltage circuit unless qualified, because the capacitor can retain a lethal charge even when the microwave is unplugged.

Pro Tip

High-voltage microwave components should be serviced by a qualified technician because the capacitor may retain a dangerous electrical charge.
