Oven heats but food cooks unevenly — top browns while bottom stays raw, or one rack cooks faster than another due to failed convection fan circulation.
Convection fan blade does not rotate when Convection Bake or Convection Roast mode is selected, preventing proper hot air distribution.
Grinding, buzzing, squealing, or rattling sounds from the rear of the oven cavity caused by worn motor bearings or a seized motor.
Without convection airflow, the oven sensor near the broil element gets a false reading and the oven struggles to reach and maintain set temperature.
Convection fan starts then stops intermittently during baking, causing inconsistent cooking results and unexpected temperature drops.




💡 Pro Tip: Is Your Convection Fan Motor the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Oven runs but food cooks unevenly — one side browning faster than the other
⚠️ Convection fan does not spin at all when convection bake cycle is selected
⚠️ Loud buzzing, grinding, or rattling noise coming from the back of the oven cavity
⚠️ Fan spins intermittently or stops mid-cycle, causing temperature fluctuations
🛠 Diagnostic tip: The convection fan motor should ONLY run when the Convection Bake or Convection Roast cycle is selected — if it doesn't spin at all in those modes (but the oven heats), the motor has failed. Use a multimeter to check for continuity at the motor terminals; an open circuit confirms replacement is needed.
