Possible Causes
Failed convection fan motor, Open convection heater element, Loose wiring to fan or heater, Faulty relay on main PCB
How to Fix / Troubleshooting
Safety: Disconnect power. Convection models have additional high-temperature components that can be hazardous.
- Mode check: Confirm that the error appears when using convection or combination modes. Try standard microwave-only mode to see if it operates normally.
- Inspect interior fan cover: Look at the rear wall inside the cavity where the convection fan is located. Check for obstructions or warped covers.
- Clean vents: Remove any food debris or grease buildup around the convection fan intake and exhaust areas.
- Service required: Testing the convection fan motor and heater element requires access behind the cavity and use of a meter. Have a technician test continuity of the fan motor and heater and inspect the control board relays.
