Error codeE1
ApplianceRefrigerator
Quick answer
E1 means thermistor 1 open. It appears in current U-Line error logs and in the older Echelon and Origins lists.
Model compatibility: U-Line reuses codes across series and model years, so E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Thermistor 1 open.
E1 means thermistor 1 is open. It is recorded in the error logs of U-Line refrigerators, wine cabinets, beverage centers and ice machines.
Current models
The current models listed in the manuals include the refrigerator, wine cabinet and beverage center lines, the clear ice machines, the nugget ice machine and the outdoor clear ice machine. All of them list E1 as thermistor 1 open.
Older Echelon and Origins models
The legacy Echelon lists carry E1 with the same meaning, though it is not available on the CLR2160. The Origins 1115 and 1175 lists run E1 through E6.
What to do
The manuals give no owner step for E1. Diagnosing an open thermistor circuit is technician work, so note the code and call for service.
Call (310) 879-5776 for U-Line refrigerator repair in Los Angeles. A short note of the code, the model number and any other codes in the log will speed the call.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
