U-Line Ice Maker Error Code 10

Error code 10 on a U-Line ice maker is a Door 2 open error. It means the control board is detecting that the secondary door is open or that the door switch is not registering a closed position. This can interrupt normal ice-making operation until the condition is resolved.

A reset may temporarily clear the code from the display, but if the underlying cause, such as a misaligned door or a faulty door switch, has not been corrected, the error will return. It is important to diagnose and fix the root cause before relying on a reset.

If the fix is simply a door realignment or clearing an obstruction, there may be little to no parts cost involved. If the door switch needs replacement, parts typically cost in the range of $15 to $50 depending on the specific switch required, with additional labor costs if a technician is involved. A door gasket replacement, if needed, generally falls in the $20 to $75 range.

Start by checking that Door 2 is fully closed and that nothing is obstructing it. Inspect the door alignment and hinges to make sure the door seats evenly against the cabinet. If the door appears properly closed, test the door switch for continuity using a multimeter. A failed switch will need to be replaced to clear the error.

While a door open error is not typically an immediate safety hazard, leaving it unaddressed can affect the unit's performance. An unresolved door fault may cause the ice maker to pause production cycles or allow temperature fluctuations that reduce efficiency and ice quality.
