U-Line Origins 1000 Code E3: Door Left Open Alert
On a U-Line Origins 1000 refrigerator, E3 warns that the door has been open for more than 20 minutes. It clears when the door closes fully, and it is an alert rather than a broken part.
What does U-Line refrigerator & drawers code E3 mean?
Origins 1000 refrigerators, including the 1115R, 1175R and 1175WC, put E3 on the display once the door has stood open past 20 minutes. It warns about the door and says nothing about a failed part. Shutting the door firmly clears it. On an Echelon 2000 the same code also takes in the bottom drawer along with the main door, which is wider than the single door here. Until the door closes, the alert stays on the display.

How the refrigerator & drawers detects E3
An Origins 1000 refrigerator senses its door with a switch. While the door is shut, the switch tells the control everything is normal. Once the door opens, the control begins counting. If the opening lasts more than 20 minutes, the control concludes the door has been forgotten rather than used, and it posts E3 on the display to get your attention. Nothing in the cooling system has broken at that point; the control is simply reporting what the switch tells it. Closing the door restores the closed signal, and the code leaves the display. When E3 lingers after a shut door, the control is still receiving an open signal, so attention turns to the switch or to how the door sits against it, rather than to the cooling.
Why E3 appears
- A door left standing open
- A bottle or shelf item propping the door off its seal
- A door switch that fails to register the closed door
Can you keep using the refrigerator & drawers with E3?
Yes. Close the door and E3 goes away, so the refrigerator can go on working as normal. After a long open period, check the cabinet with a thermometer instead of trusting how the food feels, because room air warms it quickly. Food that sat above 41 F for hours should be thrown out. If E3 stays up with the door fully shut, keep watching the temperature until the switch is checked.
What you can safely check
- Nothing needs to be turned off; simply close the door firmly.
- Shift any bottle, box or shelf that keeps it from shutting.
- Wipe the gasket and see that it lies flat against the frame.
- Check the display and see whether E3 disappears.
- If E3 stays after the door is shut, let us know.
What our technician does for E3
- Test the door switch and its alignment
- Replace the switch if it does not register a closed door
- Check the gasket and hinge for anything holding the door ajar
How to keep E3 from coming back
- Check the door after loading groceries; a bottle or tall box can hold it just off the seal.
- Keep the gasket clean so the door seats flat and the switch reads it closed.
- Avoid overloading the door shelves, which can make the door swing back open.

E3 questions
What triggers E3 on an Origins 1000?
The door being open for over 20 minutes. The control displays E3 to alert you, and the alert goes away once the door is shut. No part has to fail for it to appear.
E3 stays on after the door is shut. What does that mean?
The control still believes the door is open. That points to the door switch or how the door lines up with it, and a technician can test and replace what is needed.
Will a long open door hurt the food?
Warm room air gets in fast. Take a thermometer reading after any long open spell, and discard perishables that stayed above 41 F for hours. With the door closed, the cabinet cools on its own again.
Is E3 on an Origins 1000 a sign of a failing part?
Not by itself. It is an alert that the door stayed open too long, and closing the door clears it. A part is only in question if E3 remains after the door is completely shut.
How does this differ from E3 on an Echelon 2000?
The code and the 20-minute wait are the same, but the Echelon 2000 version also watches the bottom drawer. On an Origins 1000, the alert is only about the door.
Something else going on with your refrigerator & drawers?
A technician finds the cause at your bar or lanai and puts the price in writing before any part comes out.
