Join us as we explore the potential causes behind a Sub-Zero refrigerator not cooling while the freezer continues to function flawlessly.

 Sub-Zero Refrigerator Not Cooling, But Freezer Remains Cold? Let's Investigate...

SUB-ZERO NEED REPAIR?

Where to Begin:

Every investigation starts with a thorough examination. We’ll delve into common issues that could lead to a Sub-Zero refrigerator malfunction while the freezer remains operational, aiming to identify a straightforward solution or arrange for professional repair services.

Dirty or Damaged Refrigerator Door Gasket:

The door gasket plays a crucial role in maintaining a tight seal when the refrigerator door is closed, thus preventing cold air from escaping and warm air from infiltrating. If the gasket is dirty or damaged, it can compromise the seal, resulting in a warm refrigerator despite a cold freezer.

To resolve this issue:

  • Inspect the door gasket for any signs of dirt, cracks, or tears.
  • Clean dirty gaskets with a damp cloth and replace damaged ones promptly.

Frosted Over Evaporator Coils:

The evaporator coils are responsible for transporting refrigerant in a cold, gaseous state, aiding in the cooling process. A malfunction in the defrost system can lead to frost accumulation on these coils, impeding airflow and affecting the refrigerator’s temperature.

If you suspect frosted over evaporator coils:

  • Seek assistance from a professional to assess and repair the defrost system.

Faulty Evaporator Fan Motor:

The evaporator fan motor facilitates the circulation of cool air within the refrigerator. A malfunctioning fan motor can disrupt this airflow, resulting in temperature imbalances between the refrigerator and freezer compartments.

Signs of a faulty evaporator fan motor include:

  • Loud operation.
  • Difficulty in manually turning fan blades.
  • Lack of continuity as revealed by multimeter testing.

If these signs are present, it’s advisable to have the fan motor replaced by a professional.

Defective Thermistor:

The thermistor monitors the refrigerator’s internal temperature and communicates with the control board to regulate cooling operations. A defective thermistor can lead to inaccurate temperature readings and improper cooling.

To address this issue:

  • Conduct multimeter testing to check for continuity.
  • Replace the thermistor if necessary.

Condenser Coils in Need of Cleaning:

Regular maintenance of condenser coils is essential for optimal cooling performance. Dust and debris accumulation on these coils can impair their ability to cool refrigerant effectively, resulting in a warm refrigerator despite a functional freezer.

To clean condenser coils:

  • Turn off the refrigerator’s power.
  • Locate and access the condenser coils.
  • Use a vacuum brush attachment to remove dust and lint.
  • Restore power to the refrigerator after cleaning.
