Sub-Zero Error Codes – Solutions

Here are the common error codes you will find in a Sub-Zero refrigerator and how to fix them:

1. EC06

When you see this error code, it means the thermistor reads open or shorted for more than 10 seconds. The error code can also mean that the thermistor of the evaporator in the refrigerator has read irregular temperatures on different occasions.

To fix it, you will need to employ the services of a qualified service agent. This is to help you verify the fault accurately and fix it properly.

2. EC20

The error code EC20 indicates that the bi-metal defrost thermostat is defective.

To fix this, turn off the refrigerator by unplugging it or shutting the circuit breaker off. After about 30 seconds, turn the refrigerator on again. The error code should disappear. But if it doesn’t, contact a qualified technician or a Sub-Zero service agent for help.

3. EC24

This error code means that the defrost heater is not heating enough to carry out its job.

To fix it, call a Sub-Zero repairman or any other qualified technician to verify the cause of the error and fix it.

If the internal temperature of the refrigerator is normal, then clean the condenser coils. This is to keep the compressor from operating more than needed because it is trying to keep the refrigerator from getting warm.

To clear the code, press the Door Ajar Alarm button and hold it for about 15 seconds.

4. EC40

When you see the EC40 error message, then you know that the compressor of the freezer is running non-stop. That means that the freezer is operating without a break.

Check the internal temperature of the freezer. If it is normal, then clean the condenser coils so that they can effectively release heat and the compressor won’t have to run non-stop. Then, clear the code by pressing the Door Ajar Alarm button and holding it for about 15 seconds.

But if the internal temperature is high, even with the compressor running constantly, have a qualified technician take a look at it to find out the cause of the high temperature.

5. EC50

This error code means that the compressor of the refrigerator is operating non-stop. So, the refrigerator is not getting any break.

If this is the case, then check to be sure that the door is not left open for long and that he door seal is sealing tightly. Also, ensure it is not opened often. Be sure that there isn’t too much food in the unit and that the food is not hot. Reduce the amount of food and let the hot one cool before storing it in the refrigerator.

Additionally, check the temperature of the room where the refrigerator is and the internal temperature of the unit. Keep the refrigerator in a cooler place and away from any direct heat source.

Clean the condenser coils thoroughly and check the blades of the condenser fan for obstruction. Be sure that they are spinning properly. These will help reduce the run time of the compressor.

However, if none of the above applies, contact a professional repairman or call Sub-Zero help center. This is because the problem could be a leak in the sealed system.
