U-Line Echelon 2000 ER (alternating with SP): Stored Error Summary
On a U-Line Echelon 2000 refrigerator, a display that alternates between ER and SP means at least one error is stored. ER only summarizes it, and the exact code is read in diagnostic mode.
What does U-Line refrigerator & drawers code ER (alternating with SP) mean?
On Echelon 2000 refrigerators using the 2010 electronic control (2175RF and 2275ZWC are examples), the display switches back and forth between ER and SP while any error is stored. ER does not name a specific problem. A technician reads the exact code, or the combination, in diagnostic mode, from options 2, 19, 20 and 21 in the thermistor status list.

How the refrigerator & drawers detects ER (alternating with SP)
The 2010 control watches its thermistors and records any error it finds. ER is the display's way of saying that at least one record is waiting. Instead of showing a code, the display alternates between ER and SP, the set point, so the refrigerator still tells you the temperature you chose while warning you that something is stored. The detail is held inside. A technician opens diagnostic mode and reads it from options 2, 19, 20 and 21 in the thermistor status list. That is the only way to learn which sensor circuit raised the entry, and whether one code or a combination is stored. An old entry can also remain in the log after a repair, which is why the log is cleared only once it has been read.
Likely causes of ER (alternating with SP)
- One or more thermistor errors stored in the control
- Several codes held at the same moment
- An error left in the log after an earlier repair
Can you keep using the refrigerator & drawers with ER (alternating with SP)?
Often you can, but not blindly. ER only says that errors are stored; it does not say which one. A condenser thermistor failure stops the refrigerator completely, while other codes leave it running. Check the cabinet with a thermometer, and if the refrigerator has stopped or the cabinet is warming, move perishables to another cooler. Do not clear anything until the codes have been read.
What you can safely check
- Unplug the refrigerator for a minute and restore power to see whether the display returns to ER and SP.
- Write down that the display alternates between the two.
- Make sure the door shuts fully and nothing blocks the grille.
- Should ER and SP return, tell us and we will read the exact code. Keep all panels closed.
What our technician does for ER (alternating with SP)
- Read the stored codes in diagnostic mode from the thermistor status list
- Repair the sensor circuit or part the code names
- Clear the error log after the repair so new entries stand out
How to keep ER (alternating with SP) from coming back
- Have any code read promptly when it first appears, before several errors pile up behind ER.
- Keep the grille clean and the door sealed, so airflow and temperature problems do not add more entries.
- Clear the log only after the stored codes have been read and the repair is finished.

ER (alternating with SP) questions
Why does my display alternate between ER and SP?
The control swaps ER with the set point whenever any error is stored, without saying which. A technician reads the exact code from the thermistor status list in diagnostic mode.
Does ER mean the refrigerator has stopped?
Not always. ER stands for any stored error, alone or combined. Only a failed condenser thermistor stops every function; other codes leave the refrigerator running, so the real code gets read first.
Should the error log be wiped?
Option 12 in diagnostic mode wipes it, but only after the codes are read and the repair is done, so that a repeat entry stands out.
Is ER a code I can look up?
ER is a summary and not a specific problem. It tells you errors are stored, and the actual code or combination has to be read in diagnostic mode, so there is no single meaning to look up.
What should I tell you about ER and SP when I phone?
Say that the display alternates between ER and SP, give the model, and tell us whether the refrigerator is still cooling. That helps decide how soon the stored codes need to be read.
