How to Fix / Troubleshooting

Safety first: Isolate the oven from mains power.

Steps to check:

Spin test: With the oven cool, open the door and gently spin the fan blade by hand. It should rotate freely. If stiff or jammed, the motor is likely failing.
Access motor: Remove the rear panel of the oven cabinet to access the convection fan motor assembly.
Wiring check: Inspect the motor connectors for looseness or heat damage. Reseat connectors.
Resistance test: Measure resistance across the motor terminals. An open circuit indicates a failed motor.
Replace motor: Remove mounting screws, detach the fan blade from inside the cavity (usually a central nut), and install a new Tower-compatible convection fan motor and blade.

Note: If the motor is good but not receiving power, the control board or relay may be faulty and should be tested by a professional.

Oven shows E6 and the convection fan does not run in fan-assisted modes.
