Whirlpool Refrigerator Not Cooling — Fix Guide

What Does This Error Mean?

A Whirlpool refrigerator that is not cooling is usually caused by dirty condenser coils, a failed evaporator fan motor, or ice build-up from a faulty defrost system. Check that condenser coils at the back or underneath are clean, and listen for the evaporator fan inside the freezer.

Affected Models

Whirlpool French Door Refrigerator
Whirlpool Side-by-Side Refrigerator
Whirlpool Top Mount Refrigerator
Whirlpool Bottom Mount Refrigerator

Common Causes

Dirty condenser coils — heat cannot escape
Evaporator fan motor failed — cold air not circulated
Defrost system fault — ice blocks evaporator airflow
Door gasket worn — warm air constantly entering
Condenser fan motor failed

How to Fix It

Clean the condenser coils.

On most Whirlpool models, condenser coils are located underneath the fridge behind the toe grille. Pull off the grille and vacuum the coils with a brush attachment. Dusty coils are the most common and most overlooked cause of poor cooling — clean them every 6–12 months.
Listen for the evaporator fan.

Open the freezer door and listen for a fan running near the back wall. If you can hear the compressor humming from the back of the fridge but no fan sound from inside the freezer, the evaporator fan motor has likely failed. A fan replacement is a moderate DIY repair.
Check for ice build-up behind the freezer panel.

Remove food from the freezer and unscrew the rear interior panel. A thick layer of ice on the evaporator coils indicates the defrost heater or defrost thermostat has failed. Thaw manually by leaving the doors open for several hours, then monitor to see if cooling returns.
Check and adjust temperature settings.

Confirm the fridge is set to 3°C (37°F) and the freezer to -18°C (0°F). Also check that the temperature controls were not bumped — this is easy to accidentally do when placing food.
Inspect the door gaskets.

Run your hand around the fridge and freezer door seals feeling for cool air leaks. A damaged gasket cannot be seen easily — use the dollar-bill test: close the door on a note and pull; it should grip firmly. Replace worn gaskets to restore efficiency.

When to Call a Professional

If the compressor runs but the fridge is not cooling after coil cleaning and defrosting, the refrigerant may be low or the start relay has failed. These are service-level repairs requiring a certified technician.
