Error codeER
ApplianceRefrigerator
Quick answer
ER on legacy Echelon models signals a thermistor failure, with the exact error read in service mode.
Model compatibility: U-Line reuses codes across series and model years, so ER 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
ER indicates a thermistor failure on legacy Echelon models; the exact error (E1-E9) is read in service mode, and ER alternates with SP.
ER appears on older Echelon refrigerators, wine cabinets, beverage centers, clear ice combo units and clear ice makers, including the CLR2160 and CLRCO2175.
What it means
The display shows ER when there is a thermistor failure. It does not say which one. The exact error from E1 to E9 is read in service mode. Errors or combinations of errors alternate ER with SP on the display.
Owner action
The manual gives owners nothing to try for ER, so the next step is to have a technician read the specific error.
If this code keeps coming back on a U-Line refrigerator in Los Angeles, call (310) 879-5776 or read about U-Line refrigerator repair. It helps to have the code, the model number and a note of anything you tried on hand.
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.
