Severity is a quick triage hint—not a substitute for in-home diagnostics.

E1 Moderate

E1 – Refrigerator error code

Your Uline refrigerator is showing E1. On the under-counter and built-in refrigeration line that character typically points to a thermistor or temperature-sensor signal the control board cannot read as expected—often an open-circuit branch of the sensor diagnostic.Note the cabinet temperature with a separate thermometer, listen for the compressor…

E2 Moderate

E2 – Refrigerator error code

E2 on a Uline refrigerator is usually grouped with the same sensor branch as E1 but for a short-circuit reading instead of an open. The control board is telling you the temperature signal is outside the normal window the firmware expects.Confirm the cabinet is still cooling—touch the side…

E3 Moderate

E3 – Refrigerator error code

E3 often involves a defrost-cycle sensor or evaporator-temperature path on Uline refrigeration. Some Uline series flag E3 when the defrost element or its sensor disagrees with what the control expects during a normal cycle.You may see frost build-up at the back wall, water in the drip tray, or…

E4 Moderate

E4 – Refrigerator error code

E4 on a Uline refrigerator typically ties to a fan-related diagnostic—evaporator or condenser fan motor speed feedback that the board cannot confirm. You may hear the compressor running while interior temperatures slowly drift.Listen at the front grille (condenser side) and inside the cabinet (evaporator side) for the usual…

E5 Moderate

E5 – Refrigerator error code

The display is showing E5. On most Uline refrigeration controls that points to a communication or relay-state check inside the appliance—an internal signal that did not respond inside the expected window.Document whether the cabinet is still holding temperature and whether door alarms also misbehave. Communication errors often come…

E6 Moderate

E6 – Refrigerator error code

E6 usually relates to a door-state or interior-light diagnostic on Uline refrigerators. The control may be flagging a stuck door switch, a stretched gasket, or a sensor that the firmware cannot read cleanly.Open and close the door slowly and watch the interior light—if it stays on or flickers…

E7 Moderate

E7 – Refrigerator error code

E7 on this Refrigerator family is best read alongside how the cabinet feels (cold, warming, frosted unevenly), whether fans run, and whether alarms repeat after you complete the manual’s safe steps.Do not chip frost off coils, force a stuck drawer, or remove sealed access panels without training—what you…

E8 Moderate

E8 – Refrigerator error code

When E8 appears on a Uline Refrigerator, pause and note what the appliance was doing: holding temperature, mid-defrost, ice-harvest, or right after a power blink. Those details help a technician separate a one-time reset issue from a repeating error.Trash compactors flag separate codes for sensors, drawer state, and…

E9 Moderate

E9 – Refrigerator error code

When E9 appears on a Uline Refrigerator, pause and note what the appliance was doing: holding temperature, mid-defrost, ice-harvest, or right after a power blink. Those details help a technician separate a one-time reset issue from a repeating error.Trash compactors flag separate codes for sensors, drawer state, and…

E10 Moderate

E10 – Refrigerator error code

E10 is one of the higher-number codes in the Uline refrigerator chart and often signals a control-board / memory or general system error rather than a single sensor branch. The appliance may continue running, but the board has noted something outside the routine.Photograph the rating plate (commonly inside…
