What ER (alternating with SP) means

On U-Line Echelon 2000 refrigerators with the 2010 electronic control, such as the 2175RF and the 2275ZWC, the display alternates between ER and SP whenever the control holds one or more errors. ER is a summary, not a specific code. The exact code, or a combination of codes, is read in diagnostic mode through the thermistor status options 2, 19, 20 and 21.

Common causes of ER (alternating with SP)

  • One or more stored thermistor errors
  • A combination of codes held at the same time
  • An error that remains in the log after a repair
✓ One safe check you can try

1. Write down that the display alternates ER and SP. 2. Unplug the unit for one minute and restore power to see whether it returns. 3. Check that the door closes and the grille is clear. 4. If ER and SP come back, call us so the exact code can be read. Do not open any panel.

! Why to stop there
  • The real code is hidden behind the ER summary
  • Reading it takes the control's diagnostic mode
  • Clearing the log before reading it erases the clue
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

ER (alternating with SP)ER (alternating with SP) questions
Why does my display flash ER and SP?

The control alternates ER with the set point when any error is stored. It does not say which one. We read the exact code in diagnostic mode, using the thermistor status options.

Does ER mean the unit stopped?

Not always. ER is the summary for any stored error or combination. A condenser thermistor failure does stop all functions, while other codes leave the unit running, so we read the code first.

Can the error log be cleared?

Yes, option 12 clears the error log in diagnostic mode. We clear it only after we read the codes and finish the repair, so a repeat entry stands out.
