Refrigerator Not Cooling? 7 Common Causes and Fixes

A refrigerator that runs but doesn't cool is one of the most common appliance complaints we see. Before calling a technician, check these: dirty condenser coils (dust buildup acts as insulation), a faulty door gasket leaking cold air, and overpacking that blocks airflow.

If those are fine, the likely culprits are a failed start relay (a clicking sound every few minutes is the giveaway), a defective thermostat, a frozen evaporator fan, or low refrigerant from a slow leak. These require proper tools to diagnose.

Continuing to run a fridge with a failing compressor relay can permanently damage the compressor — the single most expensive part. If basic checks don't restore cooling within a few hours, book a diagnosis before a small repair becomes a compressor replacement.
