Sub Zero Refrigerator Problems

Here are the most common problems and the procedures of Sub Zero Refrigerator problems that you should know before calling a repairer.

1. Sub Zero Fridge Not Cooling:

We are going to start the Sub Zero Refrigerator Troubleshooting with the most common problem i.e. Sub Zero Refrigerator not cooling.

There are a few issues that might be the reason for your refrigerator not cooling.

The first problem is the compressor is not running. If you turn the compressor on, the temperature should increase in a few seconds.

If it doesn’t, there’s something wrong with the electrical connection.

The second problem is the evaporator is not running, and it could be that the evaporator coil is clogged with debris.

You should try to clean the evaporator coil with a vacuum cleaner. If the problem persists, then you should call a Sub Zero technician to repair the problem.

The next problem is the thermostat is defective. If the thermostat is defective, then it will not allow the compressor to turn on. You should remove the thermostat from the compressor and inspect it.

2. Refrigerator Leaking From Bottom:

Another common problem with a Sub Zero refrigerator is leaking from the bottom; a faulty water seal causes this.

Check the water seal for leakage, and the seal should be flat against the door and flush with the edge of the door. If there is any sign of water leakage, you need to replace the seal.

3. Refrigerator Not Defrosting:

Check the defrost timer to see if it is set to the correct time, and if the defrost timer is not set correctly, then the refrigerator will not defrost. 

4. Air Leaks:

This can be caused by a damaged gasket or a defective door seal.

5. Problems with The Refrigerator Door:

The door seal is responsible for keeping the air in the fridge sealed up. It is possible that the seal is defective and allows air to enter the fridge.

You should inspect the seal for signs of wear and tear. If the seal is damaged, then you should replace it.

6. Faulty Compressor:

There could be a mechanical problem in the compressor that needs to be fixed immediately.

7. Sub Zero Refrigerator Temperature Problems

If your Sub Zero refrigerator is not maintaining the correct temperature, there are a few potential causes and solutions to consider.

Here are some possible issues to investigate:

  • The refrigerator door may not be sealing properly, allowing cold air to escape and causing the temperature to rise. Make sure the door is closing properly and check for any damage or wear and tear on the seal.
  • The evaporator coils may be dirty or blocked, preventing the refrigerator from cooling efficiently. Clean the coils regularly to ensure they are functioning properly.
  • The thermostat may be set incorrectly or malfunctioning. Check the thermostat settings and make any necessary adjustments. If the thermostat is faulty, it may need to be replaced.
  • The condenser coils may be dirty or blocked, preventing the refrigerator from releasing heat efficiently. Clean the coils regularly to ensure they are functioning properly.

  • The freezer drawers may be overloaded, preventing proper air circulation and causing the temperature to rise. Make sure you are not overloading the drawers and allow enough space for proper air circulation.
  • The freezer drawers may be frosting up or accumulating ice, which can interfere with the proper functioning of the drawers. Make sure you are regularly cleaning and defrosting the drawers to prevent this issue.
