U-Line Refrigerator E4 Error Code

You are unlikely to see a live E4 on a recent U-Line unit, and on an older one it is a note in a log rather than an alarm.

Where E4 appears

The error log in the UHRE, UHWC, UHBD, UHRI and UHRF manuals lists E4 as thermistor 4 open, followed by the words that it does not apply to the model. These manuals also say faults are kept in memory and that only a door error is shown on the display with an audible signal.

Echelon and Origins units use E4 differently. It records that the compressor ran the whole time between two defrost cycles. That entry is never shown on the display and only turns up in the error log.

What this means for you

The manuals give no owner action for E4. If you have read it in the log and the refrigerator, wine cabinet or beverage center is not holding its temperature, a technician is the right next step.

Related codes

• E3, thermistor 3 open, which does apply to current models.
• E8, the shorted counterpart to thermistor 4, also marked as not applicable.
• E11, a memory error that is also found through the log.
