Possible Causes
Failed convection fan motor, Obstructed fan blade, Faulty convection relay on EOC, Broken wiring to convection motor
How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before accessing the fan.
- Check for obstruction: Remove the convection fan cover inside the oven and ensure nothing is blocking the fan blade.
- Spin test: Gently spin the fan by hand. If stiff or seized, the motor likely needs replacement.
- Continuity test: Access the rear of the oven, disconnect the convection motor, and test for continuity. Replace if open.
- Voltage check: During a convection cycle (only if qualified), verify that the motor receives proper voltage. If not, suspect the EOC or wiring.
