How to Fix / Troubleshooting

Safety first: Disconnect power and allow the oven to cool completely.

Access fan: Remove the oven's rear interior panel to expose the convection fan and shroud.
Check for obstructions: Look for loose screws, foil, or food debris blocking the fan. Remove any obstructions.
Spin test: Try turning the fan blade by hand. If stiff or seized, the motor likely needs replacement.
Electrical test: From the rear of the oven, access the fan motor terminals and measure resistance. An open circuit indicates a failed motor.
Replace motor: Remove the fan blade and motor mounting screws, then install a new Gram convection fan motor. Ensure the blade is refitted securely.

Warning: Sharp edges inside the oven can cause cuts; wear gloves.

Oven fan (convection) does not run in fan-assisted modes; heat may be uneven.
