Sub-Zero Refrigerator fan motor package / refrigerator evaporator fan motor replacement; fan blade not included 4200170

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Warm or uneven refrigerator temperatures, such as a warmer upper compartment
• Little or no airflow from the refrigerator air outlets
• Humming, vibrating, grinding, or other abnormal noise associated with the refrigerator evaporator fan
• Fan stops, fails to start, or operates intermittently when the refrigerator door is closed

Check Before Replacing

• With the appliance operating, listen for the refrigerator evaporator fan and compare operation with the refrigerator door open versus closed; do not conclude that the motor is faulty from this check alone.
• Visually inspect for ice buildup, food packaging, or other obstructions near the refrigerator fan blade or shroud.
• Confirm that the fan blade is present, correctly positioned, and not visibly damaged; the 4200170 package does not include the blade.
• If service access is already available, inspect the motor connector and wiring for a loose or visibly damaged connection without forcing or modifying the wiring.
• If electrical testing is required, have a qualified technician verify motor power and related fan-switch operation because warm temperatures can have causes other than the motor.

Installation Notes

• 4200170 is supplied as a motor package and does not include the refrigerator evaporator fan blade; retain or separately source the correct blade for the appliance.
• Confirm that the existing fan blade, bracket, rubber grommet, shroud, and mounting arrangement are serviceable before installation.
• Disconnect appliance power before accessing or handling the fan-motor wiring or assembly.
• After installation, verify that the blade rotates freely without contacting the shroud or nearby components and that airflow returns when the refrigerator fan is commanded on.
• Use the appliance-specific service documentation or a qualified technician for access, wiring, and final operational checks.
