How to fix it
- Power off and let the oven cool completely.
- Remove the rear cavity panel inside the oven.
- Verify the convection fan blade is tight on the motor shaft.
- Spin the motor by hand — should turn smoothly with no grinding.
- Check motor resistance with a multimeter — open winding means replace the motor.
- Replace the convection fan motor; if a new motor still throws E0531, replace the main control.
