Fridge Not Cooling? 7 Common Causes and What to Do Next

Few things create panic in a kitchen faster than a warm fridge. Groceries are at risk, the freezer is starting to thaw, and you need answers fast. Before you assume the worst, run through these seven common causes. Some have simple fixes you can do yourself in minutes.

1. The Temperature Setting Got Bumped

It sounds obvious, but it happens constantly. A jug of milk or a curious kid can nudge the dial or touch controls. Check that the fridge is set between 1.5 and 3 degrees Celsius and the freezer at minus 18.

2. Blocked Air Vents Inside the Fridge

Cold air circulates through vents between the freezer and fridge compartments. If groceries are packed tight against those vents, parts of the fridge stay warm. Rearrange items so air can move freely.

3. Dirty Condenser Coils

Dusty coils are the number one cause of poor cooling that our technicians find in Kitchener and Guelph homes. Unplug the fridge, locate the coils on the back or underneath, and vacuum them clean. Many "broken" fridges come back to life after this alone.

4. A Worn Door Gasket

Close the door on a piece of paper. If it slides out easily, the seal is not holding and warm air is leaking in around the clock. Gaskets are an inexpensive replacement part.

5. A Failed Evaporator Fan

If the freezer is cold but the fridge section is warm, the fan that pushes cold air between compartments may have failed. You might hear unusual noise from the freezer area, or nothing at all where there used to be a hum. This is a repair job for a technician.

6. Frosted-Over Evaporator Coils

A failed defrost system lets ice build up until air cannot pass through the coils. The telltale sign is a fridge that works after being unplugged for a day, then warms up again. The underlying defrost component needs to be diagnosed and replaced.

7. A Failing Compressor or Refrigerant Issue

If the fridge runs constantly but never gets cold, or clicks repeatedly without starting, the compressor or sealed system may be the problem. On an older fridge this is the point where you should weigh repair against replacement.

What to Do While You Wait

Keep the doors closed as much as possible. A full fridge holds its temperature for about four hours, and a full freezer for 24 to 48 hours. Move critical items to a cooler with ice if the repair will take longer.
