Common Symptoms

  • Microwave not heating
  • Microwave sparking or arcing
  • Loud or noisy microwave operation
  • Burning smell from the microwave

Check Before Replacing

  • If the microwave runs without heating, the diode may be involved, but the magnetron, capacitor, transformer, and other high-voltage components can produce similar symptoms.
  • A visibly burned diode can indicate failure; microwave high-voltage circuits may retain a lethal charge even after unplugging, so internal testing should be performed by a qualified technician.

Pro Tip

Verify the complete appliance model number before ordering; this diode is used across multiple Whirlpool-family microwave models.
