It can be quite frustrating when your freezer is working, but your refrigerator isn’t. As confusing as this problem is, it’s actually quite common. We get calls from customers every year asking, “Why is my refrigerator not cool but freezer working?” There can be several potential answers to this confusing refrigerator problem.

Refrigerator Not Cool but Freezer Working? This May Be Why.

If your refrigerator freezer not working is becoming a problem, there are a variety of common solutions, from simple fixes to major repairs. Let’s take a look at some of the most common “refrigerator warm freezer cold” causes and solutions.

Do You Need to Defrost Your Freezer?

Every time you open your freezer door, warm, moist air from the outside is brought in. The moist air turns into frost once the freezer door is closed again. This frost can build up over time, creating extra ice on the interior of your freezer…and lots of it. This ice can build up on vents and evaporator coils, which can cause the problem of a refrigerator not cooling but freezer is fine.

Many modern freezers come with auto-defrost options, but if you have an older model refrigerator-freezer, you will certainly need to manually defrost your freezer from time to time. Defrosting a freezer once a year is generally recommended. If you’d like more information on how to defrost your freezer, take a look at Whirlpool’s guide on How to Defrost Your Freezer.

Is Your Freezer Overpacked?

Overpacking a freezer can actually cause quite the refrigerator problem. The freezer allows cold air to flow from vents into your refrigerator. If these vents become obstructed by too many items in your freezer, it will cause the problem of a refrigerator not cool but freezer working.

Here’s an example of a freezer that is overstuffed.

To prevent overpacking problems from occurring, you’ll want to make sure the cold air has plenty of space for air to flow. Make sure the vents in your freezer do not become covered or obstructed, and that your frozen items are not stacked too closely together.

Is Your Evaporator Fan to Blame?

An evaporator fan malfunction can cause a refrigerator not cool but freezer working issue. The evaporator fan is generally located behind the back wall of the freezer compartment.  The evaporator fan should be able to spin freely. If there is excess dust or debris on or around the fan, simply cleaning it may resolve your refrigerator problem. If the evaporator fan does not spin, or is spinning slowly, it will likely need replacement by a professional refrigerator technician.

Could It Be a Broken Thermistor?

Is the freezer working but not fridge? It may be due to a malfunctioning thermistor. A thermistor is an important part of the refrigerator that monitors the temperature and is connected to the compressor and evaporator fan. If the thermistor is not sending correct temperature readings to the other components, or no readings at all, the refrigerator and freezer will not cool correctly. A thermistor can be tested, then repaired or replaced by a professional refrigerator technician.
