Details of ER
Found on: the older Echelon line, covering refrigerators, wine cabinets, beverage centers, the clear ice combo and clear ice makers (CLR2160 and CLRCO2175 among them).
Display: ER, alternating with SP when errors or combinations of errors are present.
Meaning: one of the thermistors has failed, but ER does not say which.
Finding the specific error
Service mode shows the particular error, somewhere between E1 and E9. ER alone cannot be narrowed down.
Owner action
No owner procedure appears in the manual. Write down the model number and have the particular error read.
An Echelon unit in San Francisco or the Bay Area showing ER can be booked in on (415) 329-7078, and U-Line refrigerator repair describes the service. Tell us the model number and what the display alternates between.
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 is a thermistor failure display on Echelon models; the exact error from E1 to E9 is read in service mode, and ER alternates with SP.
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.
