U-Line Origins 1000 Code E6: Overcooling Alert
On a U-Line Origins 1000 refrigerator, E6 means the cabinet has measured 10 degrees colder than the setting for over 6 hours. The cabinet is too cold, so food can freeze.
What does U-Line refrigerator & drawers code E6 mean?
Origins 1000 refrigerators, such as 1115WC, 1175WC and 1175BEV, display E6 once the real cabinet temperature has run 10 degrees colder than the set point for longer than 6 hours. Food and bottles can freeze in that cold. The Echelon 2000 line raises the same code after a 12-hour window instead. The refrigerator keeps running while E6 shows, which is why items against the back wall freeze first.

How the refrigerator & drawers detects E6
The Origins 1000 control measures the cabinet and compares it with the set point to decide when to run the cooling and when to stop it. When the cabinet has run 10 degrees colder than the set point for longer than 6 hours, the stop decision is clearly not being carried out. The control shows E6 so the problem is visible, even though the refrigerator keeps running. Several things could keep the cooling on: the control itself, the relay that switches it, or a temperature reading that no longer matches the cabinet. The Echelon 2000 waits 12 hours before raising the same code, while the Origins reacts after 6. Because cold air settles toward the back wall, food stored there freezes before anything else.
Likely causes of E6
- A control that keeps the cooling switched on
- A temperature reading that no longer matches the real cabinet
- Cooling that keeps running after the set point is reached
Can you keep using the refrigerator & drawers with E6?
Only if you watch what is inside. The cabinet is far colder than requested, so bottles, produce and anything with water can freeze or burst. Raise the set point to see whether the control responds, and move delicate items away from the back wall. If the cabinet stays this cold, the cooling is not shutting off, and a repair is needed. A restart alone does not fix a cooling circuit that stays on.
What you can safely check
- Unplug the refrigerator for one minute, then restore power.
- Turn the set point up a few degrees on the display.
- Shift food and bottles off the back wall, where they can freeze.
- If E6 comes back, let us know and protect anything that can freeze.
What our technician does for E6
- Test the control and the relay that switches the cooling
- Check that the temperature reading matches the real cabinet
- Replace the part that keeps the cooling running
How to keep E6 from coming back
- Keep drinks and produce away from the back wall, which runs coldest.
- Glance at the cabinet temperature on a thermometer from time to time, so overcooling is caught early.
- Use a surge protector, and have the outlet checked after storms, since surges can harm a control.

E6 questions
Why is everything freezing in my Origins 1000?
With E6 the cabinet has stayed 10 degrees colder than its setting for more than 6 hours. The cooling does not stop where it should, so whatever touches the back wall freezes first.
Will a warmer setting help?
Try it and see whether the control reacts. A cabinet that stays too cold at a higher setting means the control needs testing.
Should I unplug the refrigerator?
You can unplug it for a day if the food is moved out first; otherwise restore power after a minute. Restarting changes nothing while the control holds the cooling on. Any repair is priced in writing first.
Is E6 dangerous for the refrigerator itself?
It is hard on the cooling system, which runs without rest, and it can damage what you store. Freezing can burst bottles. The sooner the control is tested, the less strain the system takes.
Does E6 differ between Origins 1000 and Echelon 2000 models?
The meaning is the same, a cabinet far under the set point. The difference is timing: Origins raises it after 6 hours, while Echelon 2000 models wait 12 hours before showing it.
