Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Freezer or refrigerator compartment is not cooling adequately when the evaporator fan does not operate.
• Uneven compartment temperatures caused by reduced cold-air circulation.
• Ice accumulation or recurring frost-related cooling problems when the included thermistor, thermal fuse, or defrost thermostat is faulty or improperly positioned.

Check Before Replacing

• With the appliance safely powered off, inspect the fan-harness connector and wiring for loose connections, damage, or signs of overheating.
• Use the refrigerator’s built-in service diagnostics, where available, to command the evaporator fan on; if the control supplies the specified operating voltage but the motor does not run, the motor assembly may be defective.
• Check the thermistor and defrost-circuit components only according to the appliance’s model-specific technical sheet; do not bypass the thermal fuse or thermostat.
• Before attributing a cooling problem to this assembly, check for heavy ice obstructing the fan and confirm that the fan blade can turn freely without forcing it.
