U-Line Origins 1000 Refrigerator E2: Shorted Thermistor
A U-Line Origins 1000 refrigerator shows E2 when its thermistor has shorted. The control sees the cabinet sensor as a dead short, so it has no usable temperature.
What does U-Line refrigerator & drawers code E2 mean?
Origins 1000 refrigerators, including 1115WC, 1175WC and 1175BEV, report E2 once the cabinet thermistor has shorted. The control reads a dead short instead of the changing resistance a healthy sensor gives, so it has no temperature to work with. The same label on Echelon 2000 models refers to thermistor 1. While E2 stays up, nothing good is feeding the control's regulation of the cabinet.

How the refrigerator & drawers detects E2
The control on an Origins 1000 refrigerator passes a signal through its single cabinet thermistor and reads the result as temperature. The resistance of a healthy thermistor shifts gradually with the cabinet. When the circuit is shorted, the resistance drops to almost nothing, and the control sees a value that does not match any real cabinet condition. It reacts by flagging the sensor as shorted and posting E2 on the display. Because that one thermistor is the only source of cabinet information, the control has nothing else to fall back on. A short can begin in the sensor itself, in wiring that has been pinched, or at a damp plug. Telling these apart takes a meter, not a visual check.
Likely causes of E2
- A cabinet thermistor that has shorted out
- Wiring near the sensor that is pinched or worn through
- Damp conditions at the sensor plug
Can you keep using the refrigerator & drawers with E2?
You can leave it running briefly, but do not rely on the display. With E2 showing, the control is working without a usable temperature, so the cabinet may drift in either direction. Check a separate thermometer often. If the reading rises, move perishables elsewhere, and if bottles start to feel icy, move them too. Keep the panels closed while you wait for the repair.
What you can safely check
- Jot down the code and the model, then unplug the refrigerator for a minute and plug it back in.
- See that neither the vents nor the door are obstructed.
- Give the display a few minutes to settle.
- If E2 shows again, watch the cabinet temperature and phone us.
What our technician does for E2
- Test the sensor circuit with a meter for a short
- Check the wiring and plug for damage or moisture
- Replace the failed part
- Check that the display goes back to showing temperature
How to keep E2 from coming back
- Wipe up spills near the cabinet floor and the control so moisture does not reach sensor connections.
- Make sure vents stay clear and the door closes fully, so condensation is less likely around the sensor.

E2 questions
How does E2 compare with E1 on this Origins line?
E1 flags an open thermistor, while E2 flags a shorted one. Each is a failure in the sensor circuit, and each ends in a sensor or wiring repair.
Could dampness cause E2?
Yes, water at the sensor plug can bridge its contacts and look like a short. The connection is dried and tested first, and the sensor is replaced if the reading stays wrong.
What does the repair involve?
Our technician measures the sensor circuit, swaps whatever part has failed and watches the display return to normal. You receive the price in writing before we begin, and the work carries a 30-day warranty.
Will E2 go away if I restart the refrigerator?
A restart may hide it for a moment, but a shorted sensor stays shorted, so E2 returns once the control checks the circuit again. If it does, the sensor and wiring need a meter test.
Does the same E2 apply to an Echelon 2000?
The label matches, but on Echelon 2000 models it names thermistor 1 specifically. Origins 1000 refrigerators have a single thermistor. Tell us the model, such as the 1175BEV, so we can bring the right sensor.
