This isolator routes microwave energy between the magnetron and waveguide to help protect components and maintain consistent heating performance. Replacing a failed isolator can restore reliable cooking and help prevent further high-voltage damage. What it does:

  • Directs RF energy from the magnetron into the waveguide/cavity
  • Helps protect the magnetron by reducing reflected energy
  • Aids in preventing arcing or burn damage in the waveguide area
  • Common symptoms of failure: no heat or uneven heating, loud humming/buzzing, visible arcing/burn marks near the waveguide
What's included:
  • 1 isolator
Install notes:
  • Disconnect power and discharge the high-voltage capacitor before servicing; risk of electric shock
  • Handle waveguide components carefully; avoid contaminating RF surfaces and note exact orientation
  • Take photos of the original setup to match positioning and fastener locations

This drawing capacitor helps provide the extra electrical boost motors need to start and run smoothly, restoring normal operation and reducing strain on the motor. It's a direct-fit replacement when the original capacitor fails. What it does:

  • Supplies a timed voltage boost to assist motor startup and rotation
  • Helps reduce motor humming, slow starts, or failure to start
  • Promotes consistent motor speed during operation for reliable performance
  • Can prevent added stress on the motor windings when functioning properly
What's included:
  • One drawing capacitor
Install notes:
  • Disconnect power to the appliance before attempting any service
  • Capacitors can hold charge—discharge safely and use insulated tools
  • Verify correct orientation and secure connections; replace only with the exact part number
