Most common repairs needed to fix a freezer

Compressor Replacement

When your freezer is running but not freezing, a malfunctioning compressor might be the culprit. The compressor's role is to compress and circulate the refrigerant gas within the sealed system, which extracts heat from the freezer's interior, maintaining its cool temperature. If the compressor fails to work as it should, the freezer won't cool properly. Due to EPA regulations governing refrigerant handling and disposal, it's essential to enlist the services of a certified technician for repairs. You can schedule service through Sears Home Services, and we'll dispatch a certified technician to your home to address the issue.

Thermostat Replacement

If your freezer is running but not freezing, a bad cold control thermostat may be causing the issue. The cold control thermostat senses freezer interior temperature and cycles the compressor on and off to maintain the set temperature on the thermostat dial. A faulty thermostat may not be sensing freezer temperature properly or may not be sending current to the compressor properly to cool the freezer. When your freezer sometimes runs but is not freezing, schedule freezer repair service to have a Sears Home Services technician fix the cooling problem.

Compressor Start Relay Replacement

When you hear fans running in your freezer but the compressor isn’t turning on, a bad compressor start relay could be preventing the compressor from starting. The compressor start relay sends current to the motor start windings to boost motor torque to start the motor, and to the motor run windings. Once the motor starts, the relay continues to send current to the run windings, but cuts off current to the start windings. A defective start relay won't send current to the start windings, run windings or both. The start relay includes an overload component that shuts off all current to the motor if the motor overheats. A defective overload trips when the motor isn't overheated, preventing the motor from starting. Have a Sears Home Services technician check the compressor start relay and replace it if it’s bad.

How to fix a freezer that is running but not freezing

Addressing most issues with a freezer running but not freezing typically involves replacing a bad compressor, faulty cold control thermostat or broken compressor start relay. However, since various factors could contribute to the problem, a thorough examination of the freezer is crucial for effective resolution of the problem. Having an accurate diagnosis made by a professional service technician if often necessary to determine the extent of the required repair.

Solutions for a freezer that runs but does not reach freezing temperatures

When your freezer isn't cooling properly, there could be numerous causes. To prevent unnecessary part replacements, we advise having a Sears Home Services expert conduct diagnostic tests to pinpoint the underlying issue. Our technicians have extensive experience in diagnosing various types of freezer malfunctions. The technician will examine the freezer and determine the exact cause of the cooling issue to accurately fix the problem.

What to watch for with a freezer running but not freezing diagnosis

It can be hard to diagnose modern appliances without the right knowledge and training. Some diagnostic techniques are complicated and you might end replacing the wrong parts. Don’t risk wasting money on parts that won’t fix the problem.

Appliances, especially those made in the last decade, have become very advanced, with electronic parts that are hard to check. Repairing the latest appliance models yourself is getting harder. To get your freezer diagnosed and repaired accurately, schedule freezer repair through Sears Home Services and we’ll send an experienced technician to your home to fix the problem.

Frequently Asked Questions

Why is my freezer running but not freezing?

Yes, if the thermostat isn’t working correctly, it may cause the freezer to run but not reach the proper freezing temperature because a faulty temperature sensor causes the thermostat to shut off the compressor too quickly.
How can I fix my freezer if it’s running but not freezing?
Check the thermostat, compressor, and refrigerant levels. Replacing damaged parts should restore proper freezing.
