This power control board assembly replaces the sub power PCB that manages electrical distribution and control signals, restoring reliable power and control to the appliance. It's a direct-fit replacement used in the appliance's control system. What it does:

  • Regulates and distributes power to key components so the appliance can operate correctly
  • Sends and receives control signals between sensors, relays, and the main control system
  • Can address symptoms such as no power to components, intermittent operation, blank or unresponsive display, or error codes related to power/control
  • Helps stop erratic behavior caused by damaged or failed circuitry on the sub control board
What's included:
  • One power control board assembly (sub PCB) as pictured
Install notes:
  • Disconnect all power (unplug or shut off breaker) before starting any repair
  • Handle the board by the edges and avoid touching components; observe electrostatic discharge (ESD) precautions
  • Some disassembly (panel removal or wiring disconnects) is typically required; keep track of mounting hardware and connector positions

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
