U-Line Echelon 2000 Code E9: Thermistor 4 (condenser) open or shorted

What E9 means

On U-Line Echelon 2000 refrigerators with the 2010 control, such as the 2175DWRR and the CLRCO2175, E9 means thermistor 4, the condenser sensor, is open or shorted. If the condenser thermistor fails, the unit stops all functions and shows ER. The code is not available on the R models, the WC models or the CLR2160. Expect no cooling until the sensor is replaced and the unit restarts.

Common causes of E9

A condenser thermistor 4 that has failed open or shorted
A damaged sensor lead or plug
An unplugged sensor at the condenser

✓ One safe check you can try

1. Check whether the unit is cooling or has stopped completely. 2. Unplug for one minute, then restore power. 3. Move perishables to another cooler if the unit stays off. 4. Vacuum the front grille with the unit unplugged. 5. If E9 or ER returns, call us.

! Why to stop there

The unit shuts down fully while this sensor is failed
The condenser sensor protects the cooling system
Food spoils while the unit is stopped

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.

E9E9 questions

Why does my unit show ER after E9?

When the condenser thermistor fails, the unit stops all functions and shows ER. Reading the control in diagnostic mode confirms E9 behind the ER. ER is the face of E9 on the display.

Is E9 an emergency?

The unit has stopped cooling, so protect the food right away. Move perishables to a cooler, then call us. Time matters because the cabinet warms while stopped.
