A refrigerator that stops cooling is the most stressful appliance failure because your food is on a timer. Before you call for repair, work through this checklist — some of these fixes take 30 seconds and cost nothing.
1. Check the Thermostat Setting
It sounds obvious, but bumped thermostat dials account for a surprising number of "not cooling" calls. Verify the temperature control is set to the manufacturer's recommended setting, typically 37°F for the fridge and 0°F for the freezer. If someone accidentally turned it to the warmest setting, that's your answer.
2. Clean the Condenser Coils
Condenser coils dissipate heat from the refrigerant. When they're coated in dust and pet hair, the compressor has to work much harder and may not cool effectively. The coils are usually behind the base grille at the front or on the back of the unit. Vacuum them with a brush attachment every 6-12 months.
3. Test the Door Seal
A worn or dirty door gasket lets cold air escape continuously. Close the door on a dollar bill — if you can pull it out easily, the seal isn't tight enough. Clean the gasket with warm soapy water first; if it's cracked or deformed, it needs replacement.
4. Check the Vents Inside the Fridge
Cold air enters the fridge compartment through vents (usually at the back wall). If food containers are blocking these vents, air can't circulate. Make sure nothing is pressed against the rear wall or blocking the vent openings.
5. Listen for the Compressor
Put your ear near the back of the fridge. You should hear a low humming sound from the compressor. If it's silent, the compressor may have failed or the start relay/overload may be bad. If it clicks on and off repeatedly, the compressor relay likely needs replacement — a common and relatively affordable repair.
6. Check If the Freezer Is Cold
In most refrigerators, the freezer produces cold air and a fan circulates it to the fridge compartment. If your freezer is cold but the fridge is warm, the evaporator fan, damper control, or defrost system may be the issue. If both compartments are warm, the problem is likely the compressor, sealed system, or condenser fan.
7. Look for Ice Buildup in the Freezer
A thick layer of frost on the freezer's back wall usually means the defrost heater, defrost thermostat, or defrost timer has failed. The ice blocks the evaporator coils and prevents cold air from being produced. This is a common repair that our technicians complete regularly.
