How to troubleshoot a Fridge That's Not Cooling

A warm fridge can spoil food. This guide covers common causes like dirty condenser coils, faulty door seals, or a broken thermostat.

Step-by-Step Fix

  1. Unplug the refrigerator and pull it out from the wall.
  2. Vacuum the condenser coils at the back or bottom to remove dust and dirt.
  3. Check the door seal by closing the door on a piece of paper – if it pulls out easily, replace the seal.
  4. Inspect the internal thermostat and ensure it's set to the correct temperature (e.g., 37°F/3°C).
  5. Listen for the compressor running; if silent, it may be faulty or the start relay may be broken.
  6. Plug the fridge back in and monitor the temperature over a few hours.
