U-Line Echelon 2000 E2 Code: Thermistor 1 Shorted
A shorted thermistor 1 is what E2 reports on a U-Line Echelon 2000 refrigerator. The control reads a dead short in place of the usual changing resistance and cannot trust its cabinet temperature.
What does U-Line refrigerator & drawers code E2 mean?
Among Echelon 2000 refrigerators on the 2010 electronic control, the 2175RF and 2175DWRR display E2 when thermistor 1 is shorted. A healthy sensor changes its resistance as the cabinet warms and cools. A shorted one reads as a dead short, which gives the control nothing it can trust. E2 shows in the place where the set point is normally displayed. The CLR2160 does not offer this code.

How the refrigerator & drawers detects E2
Thermistor 1 is the control's main window onto cabinet temperature. A working thermistor offers a resistance that rises and falls in a smooth, known way as the cabinet changes temperature. The 2010 control measures that resistance all the time. If the measurement collapses to the level of a dead short, the control knows no real cabinet could produce that value, so it marks the sensor as failed and shows E2 where the set point would normally sit. The short may start in the thermistor, in pinched wiring, or where moisture bridges the plug contacts. Once the reading is distrusted, the control cannot hold the cabinet to the set point, which makes food temperature worth watching.
Likely causes of E2
- A thermistor 1 that has shorted inside its housing
- Sensor wiring that has been pinched or damaged
- Moisture reaching the sensor plug
Can you keep using the refrigerator & drawers with E2?
Only with care. The control cannot read the cabinet correctly while E2 is showing, so the refrigerator may run too warm or too cold. Put a separate thermometer on a shelf and check it several times a day. When the reading climbs, move perishables to another cooler. Leave the panels closed, because tracing a short means measuring the circuit rather than looking at it.
What you can safely check
- Jot down the time E2 appeared, then unplug the refrigerator for a minute and restore power.
- Make sure the door shuts completely and no food is jammed against the vents.
- If E2 comes back, read the cabinet with a separate thermometer.
- Leave all panels closed.
What our technician does for E2
- Measure the thermistor circuit to confirm a short
- Inspect the wiring and the sensor plug for damage or moisture
- Replace the sensor or wiring that has failed
- Confirm the display returns to the set point
How to keep E2 from coming back
- Keep water, spills and condensation away from the area around the control and sensor plug.
- Avoid pinching cords or sensor wiring when the refrigerator is moved for cleaning.

E2 questions
How do E1 and E2 differ?
E1 reports thermistor 1 as open, and E2 reports it as shorted. The sensor is the same in both cases, but the failure in the sensor or its wiring is not, and the repair follows from that.
Should I worry about my food while E2 shows?
Watch it with a thermometer of your own, since the display cannot be trusted. If the reading climbs, put perishables in another cooler until the sensor is repaired.
Could a loose plug be behind E2?
Unlikely. A loose plug tends to read as open, which is E1. A short points to the sensor itself or to pinched wiring, and a meter test shows which.
Can humidity cause E2?
Moisture reaching the sensor plug can create a short, and Florida humidity adds to that risk if the refrigerator sits in a damp area. We dry and test the connection, then replace the sensor if the reading stays wrong.
Does E2 clear if I wait?
Rarely. A shorted sensor or damaged wire does not heal itself, so E2 comes back after each restart. Waiting only lets the cabinet drift further from the set point.
