OEM part description

This genuine Sub-Zero evaporator fan motor powers the fan that circulates cold air through select BI-Series refrigerator and freezer compartments. It is used as the motor-only service replacement when the original fan motor has failed and the remaining fan housing, blade, and mounting components can be reused.

Part details

Proper evaporator airflow is necessary to move cold air away from the evaporator and distribute it through the compartment. A worn or failing motor can cause weak circulation, warmer areas, temperature imbalance, intermittent cooling, or unusual fan noise.

Specifications / Important Notes

  • Part Type: Refrigeration air-circulation fan motor
  • Motor Type: Brushless DC evaporator motor
  • Used In: Fresh-food and freezer compartments on applicable BI-Series models
  • Replacement Level: Motor only, not the complete evaporator fan assembly
  • Operation: Powers the fan that moves cold air across the evaporator and through the compartment
  • Application: BI-Series refrigerator and freezer evaporator systems
  • Component Type: Genuine Sub-Zero service motor

Tech Tip: If airflow is weak, intermittent, or missing, verify that the control is actually calling for fan operation before condemning the motor.
