How to Determine if Your Freezer Compressor is Broken and Best Tips to Fix It

March 31, 2022

If you think your freezer compressor is broken, you can do a few freezer repairs to test it.

  • The easiest way to test it is to unplug the freezer and plug it back in. If the compressor turns on when you plug it back in, it functions properly. If the compressor doesn’t turn on, there may be a problem.
  • You can also test the compressor by feeling if it is warm to the touch. If it is warm, then it is working properly. If it is cool or room temperature, there may be a problem.
  • Finally, you can listen to see if the compressor is running. If you can hear it running, then it is functioning properly. If you cannot hear it running, there may be a problem.

If you think that your compressor is not working properly, you should call a qualified Sub-Zero refrigerator repair in Philadelphia to diagnose and repair the problem.

What are the Signs and Symptoms of a Bad Freezer Compressor?

A bad freezer compressor can cause a variety of problems for your freezer. Some of the most common signs and symptoms of a bad compressor include:

  • Increased noise from the freezer – if the compressor is working harder than it should, you’ll likely hear it buzzing or humming more than usual.
  • Decrease in the freezer’s cooling ability – if your freezer isn’t keeping things as cold as it used to, there’s a good chance the compressor is starting to fail.
  • Freezer door doesn’t close properly – if the door doesn’t seal shut, warm air can enter the freezer and cause the compressor to work overtime.
  • Freezer is leaking water – if you see water pooling around the freezer, it could be a sign of a problem with the compressor. If left unchecked, this can further damage and even mold growth.
  • Warm air leaking from the freezer – if you feel warm air coming from the freezer, it’s a sign that the compressor can no longer keep the cold air in. This is usually one of the first signs that the compressor is failing.
  • Ice buildup on the coils – if you see ice buildup on the coils, the compressor can no longer circulate the coolant properly. This can lead to the freezer not being able to maintain a consistent temperature, which can cause food to spoil.
  • Freezer not staying cold enough – if the freezer isn’t able to maintain a consistent temperature, it’s a sign that the compressor is failing. This can cause food to spoil and make the freezer less efficient.
  • Freezer shutting off frequently – if the freezer keeps turning off, it could be a sign that the compressor is overworking and needs to be replaced.

The cost to replace a freezer compressor will vary depending on the size of the unit, the make and model, and the complexity of the repair. For a small freezer, the cost may be as low as $200. For a larger unit, the cost could be $500 or more. Replacing a freezer compressor is a complex repair that a qualified technician should do. If you notice any of these problems mentioned above, it is important to have your freezer checked right away to avoid further damage.
