The code
E9
Door 2 — the lower door of a two-door unit, or the second zone of a dual-zone one. The wording moves between manuals: the undercounter boards call it door 2 (lower) open and the ice machines call it door 1 open error, which is a fair warning not to read a number off one machine's table and apply it to another.

On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

What E9 means, in the maker's own words
Door 2 — the lower door of a two-door unit, or the second zone of a dual-zone one. The wording moves between manuals: the undercounter boards call it door 2 (lower) open and the ice machines call it door 1 open error, which is a fair warning not to read a number off one machine's table and apply it to another.

From VIEW ERROR LOG, service-mode guide, in a User Guide & Service Manual downloaded from U-Line's own site. Nothing on this page is decoded beyond what that sentence says.
Where this number actually lives
Not on your display. Every U-Line manual that carries a code table says the same sentence: all errors are logged in memory, and only the door error is displayed and has an audible signal. So unless this is a door, you will not see it — it is in an error log reached by holding a hidden key for ten seconds and scrolling to the log option. That is worth knowing before you spend an evening looking for a number the appliance was never going to show you.
What to do about it
- Work out which door the control means before anything else. On a dual-zone unit the lower compartment is usually the one being complained about and it is the one people open least, so a door left ajar there goes unnoticed for hours.
- Close it, watch the alert clear, and if it does not, the switch is the suspect.
- Ask for the error log to be read. On this make the numbers live in the control's service menu — a hidden key held for ten seconds, then option 14 on the older boards and option 21 on the current ones — and the log scrolls the errors in the order they happened.
- Have the model and serial numbers ready. They are on a plate on the upper right or the rear wall of the interior, and the board also has to be programmed to the right model number for its own diagnostics to mean anything.
Where this goes next
The job this usually becomes is door switch and door alert repair, and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 851-2207 and describe what the display is doing before booking anything.
u line error codes is the broad search, and the two door numbers are what most of the people typing it have in front of them.
