Fix / Top-Freezer Refrigerator / Not cooling

Refrigerator not cooling?

A failed compressor cannot circulate refrigerant through the system, eliminating all cooling in both the fresh food and freezer compartments.

• Compressor

  Call a Pro Part: $150–$350

• Compressor Start Relay

  Easy DIY Part: $10–$30

  A failed start relay prevents the compressor from starting its run cycle, so the refrigerant circuit never activates.

• Evaporator Fan Motor

  Moderate DIY Part: $25–$60

  A failed evaporator fan motor stops cold air circulation from the freezer into the fresh food section, causing warm temperatures throughout.

• Electronic Control Board

  Moderate DIY Part: $80–$180

  A defective control board may not send operating commands to the compressor or fans, preventing any refrigeration.

• Thermistor (Temperature Sensor)

  Moderate DIY Part: $15–$40

  A faulty thermistor sends incorrect temperature readings to the control board, causing it to shut down cooling prematurely.
