Oven displays F50; convection fan may not run or oven may not heat properly in convection mode.

Safety First: Disconnect power at the breaker. Internal metal edges can be sharp; wear cut-resistant gloves.

• Check convection fan operation:
  • Start a convection bake cycle and listen for the fan (with door closed). If silent and F50 appears, continue.
• Inspect fan from inside oven:
  • Remove the convection fan cover (screws at rear of oven cavity).
  • Try spinning the fan blade by hand; it should turn freely without scraping.
  • If seized or very stiff, replace the Convection Fan Motor Assembly.
• Access rear of oven:
  • Pull the oven out from the wall (or remove from cabinet for wall ovens).
  • Remove rear panel to access the convection fan motor terminals.
  • Check for loose or burnt wires; repair as needed.
• Test motor:
  • With power disconnected, measure motor winding resistance; an open circuit indicates a bad motor.
  • If comfortable and safe, you can bench-test the motor with proper AC voltage using insulated connectors.
• Control board:
  • If the motor and wiring are good, the fan relay on the EOC may be defective; replace the Electronic Oven Control (EOC).
