So a U-Line refrigerator error code has appeared on your display? We’ve got you covered. We’ll explain a few common error codes to help you identify and solve the problem.

Troubleshooting Guide: U-Line Refrigerator Error Codes

U-Line refrigerator troubleshooting begins with cracking the codes. Let’s take a look at U-Line brand error codes.

Error Code ER

Diagnosis: Thermistor 1 is open

Explanation: The U-Line refrigerator error code ER is alerting you to a failed thermistor. Thermistors are used for various temperature readings. These provide reliable temperature readings using a resistance which varies based on surrounding temperatures. If you have a U-Line wine cooler, for example, it will include ambient temperature surrounding the refrigerator unit.

If the thermistor 1 fails, the refrigerator will continue to operate on a preset 10 minutes on and 30 minutes off time interval.

Solution: Use an accurate ohm meter to test the thermistor. If the thermistor is defective, have it replaced.

Error Code E5

Diagnosis: Thermistor 1 out of range + 10°F for more than 12 hours

Explanation: An E5 U-Line refrigerator error code may indicate service is needed to maintain cool temperatures.

The condenser coils should be cleaned at least every 3 months, sometimes more frequently. If you haven’t done this for a while, this could be the reason the temperature is higher than normal.

Solution: Inspect the condenser coil for signs of dirt and debris. Clean the coils with a dry brush and narrow vacuum attachment.

Error Code E3

Diagnosis: Main door or bottom drawer is open longer than 20 minutes

Explanation: Most likely, someone left the door or drawer ajar. It happens.

Solution: This U-Line refrigerator error code is perhaps the easiest to correct. Check to ensure everything is closed completely and nothing is blocking the closure of the main door or bottom drawer. Once things are able to close unhindered, the error code should reset.

If you’re still plagued by the “My U-Line refrigerator is displaying an error code” issue, then DIY troubleshooting may not be the right route. Contact an authorized U-Line repair service to diagnose and fix the problem.
