U-line Refrigerator Error Codes – Quick Fix

Here are the error codes in a U-line refrigerator and how to fix them:

1. E1, ER

When you see this error code, you know that thermistor 1 is open. This means that there is a failure with the thermistor. So it will not be able to accurately read the temperature using its resistance.

Test the resistance of the thermistor with a multimeter or ohmmeter. If the thermistor is not functioning, replace it with a new one.

2. E2

This error code signifies that thermistor 1 is shorted. It will need to be replaced. You can do this yourself or have a refrigerator technician replace it for you.

3. E3

You see this error code when the bottom drawer or the main door of the refrigerator is open up to 20 minutes or more. The door was probably not closed well or was left open mistakenly.

Check to see if anything is keeping the door from closing tightly. And check the door seal to be sure it is still sealing properly. If the main door or freezer drawer closes well, then this error code will automatically reset itself.

An audible alarm accompanies this error code.

4. E4
