Error codeE6
ApplianceRefrigerator
Quick answer
E6 is thermistor 2 shorted on current U-Line models, and a too-cold reading alarm on legacy Echelon and Origins units.
Model compatibility: U-Line reuses codes across series and model years, so E6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E6 means thermistor 2 shorted on current U-Line models, and thermistor 1 reading 10°F or more below set point for over 12 hours on legacy models.
Seeing E6 on a U-Line cabinet? Start by identifying whether it is a newer or older control, because the manuals assign it different meanings.
On current models
E6 is thermistor 2 shorted. It covers refrigerators, wine cabinets, beverage centers and the ice machine families that share the same code list. Faults of this type go into the error log, which scrolls them in order of occurrence; the display itself only shows a door error.
On Echelon and Origins models
The legacy meaning is thermistor 1 reading 10°F or more below the set point for more than 12 hours. This code is not available on the CLR2160. The older manual lists no owner step for it.
What to do next
No owner fix is given for either meaning. Note the model number and the exact wording you see, then ask a technician to look at it.
If this code keeps coming back on a U-Line refrigerator in Los Angeles, call (310) 879-5776 or read about U-Line refrigerator repair. It helps to have the code, the model number and a note of anything you tried on hand.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
