Jennair Refrigerator: not cooling

Possible Causes

Dirty condenser coils

How to Identify: Visible dust and debris on back/bottom coils; unit runs long without cooling; compressor hot.

Part: Condenser coils

Faulty evaporator fan or circulation fan

How to Identify: No airflow sound inside fridge; freezer remains cold while fridge warms; ice buildup near vents.

Part: Evaporator fan/air circulation fan

Damper control assembly failure

How to Identify: Cold air not flowing from freezer to fridge despite freezer cold; damper stuck closed.

Part: Damper control assembly

Temperature control thermostat or sensor fault

How to Identify: Incorrect temperature readings on display; settings change has no effect.

Part: Thermostat/temperature sensor

Compressor or sealed system failure (e.g., refrigerant leak)

How to Identify: No cooling in fridge or freezer; compressor runs but no cold produced; hissing or oil residue indicates leak.

Part: Compressor/cold‑refrigerant circuit
