U-Line Outdoor Nugget Ice Maker Code 10: Door 2 Open

What 10 means

On U-Line Outdoor Collection nugget ice makers such as the UONB115 and UONP115, the display shows 10 when Door 2 is open. The panel prints the number without a letter. The control has not detected the second door closed, so ice production pauses until it is shut and sensed. Door 1 reports as E9, which lets you tell the two doors apart at a glance.

Common causes of 10

Door 2 was left open or ajar
Something holds the door off the cabinet
The gasket on Door 2 is out of place
The second door switch is not reporting closed

✓ One safe check you can try

1. Close Door 2 and check that it latches. 2. Remove anything blocking the door edge. 3. Check that the gasket sits flat against the opening. 4. Make sure the cabinet is level. 5. Call us if 10 stays on with the door closed.

! Why to stop there

A door that is closed but reads open needs a switch test
Stored ice softens while the door is not sealed
We give a written price first and a 30-day warranty on the repair

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

1010 questions

Why do I see 10 instead of E10?

These outdoor nugget models print the number alone for Door 2. It carries the same meaning as an E-numbered door code: the second door is not sensed as closed.

Is 10 a water message?

No. On this outdoor platform 10 is the Door 2 reading. The water readings are 11 for high and 12 for low, which have their own pages.

Will 10 clear by itself?

Yes, once Door 2 is closed and the control senses it. If the code lingers with the door shut, the Door 2 switch or gasket fit needs attention from us.
