# U-Line ice maker will not turn on

### Rule out the modes before the power

On a nugget machine, holding the light button for three seconds enables Sabbath mode, and in that mode every display light goes out while the machine carries on making ice. Hold it three seconds again. If the panel comes back, nothing was ever wrong.

### Dark is not the same as dead

Two settings on these machines turn the display off while everything else carries on. Sabbath mode is one button held for three seconds and it takes every lamp with it. A locked control panel is another. Both look like a failed board from the front and neither is.

### The maker’s own order for a real power problem

Voltage at the wall outlet, then voltage at the main control’s input, then continuity of fuse F1, then a test display cycled for operation. Four checks in that order, and most control boards are cleared somewhere inside them — which matters, because the board is the expensive part and the one people replace first.

Sabbath mode

Display lights off, machine running. Easy to enable by accident and it looks exactly like a dead control.

The control panel locked

On the current cabinets a padlock icon and five seconds of holding it. A locked panel reads as a failed one.

Power, in the maker's own order

Voltage at the wall outlet, voltage at the control's input, continuity of fuse F1, then a test display. Most controls are cleared somewhere in that sequence.

The display and its wiring

The manual's own row for a dead display is both ends of the display wiring firmly connected, then a continuity test. A loom is a fraction of a board.

Hold the light button for three seconds

On a nugget machine that is how Sabbath mode is enabled and disabled, and in that mode every display light is off while the machine keeps making ice.

Look for a padlock

On the current cabinets a locked panel is unresponsive and is unlocked by holding the open padlock icon for five seconds.

Check the outlet with something else

On a built-in machine the outlet is behind the appliance and nobody has looked at it in years.

Listen with the door open

A machine that is silent and one that is running quietly are different problems, and the second one is not a power problem at all.

Nothing on the panel, or nothing after it

What it usually means

Panel lit but nothing happens

Started after a power cut

Rule out the modes before the power

On a nugget machine, holding the light button for three seconds enables Sabbath mode, and in that mode every display light goes out while the machine carries on making ice. Hold it three seconds again. If the panel comes back, nothing was ever wrong.

Dark is not the same as dead

Two settings on these machines turn the display off while everything else carries on. Sabbath mode is one button held for three seconds and it takes every lamp with it. A locked control panel is another. Both look like a failed board from the front and neither is.

The maker’s own order for a real power problem

Voltage at the wall outlet, then voltage at the main control’s input, then continuity of fuse F1, then a test display cycled for operation. Four checks in that order, and most control boards are cleared somewhere inside them — which matters, because the board is the expensive part and the one people replace first.

### It was working this morning.

Then start with power and with what else happened this morning. A breaker, an outlet behind the unit, or somebody holding a button while cleaning the panel are all more likely than a control that failed in six hours.

### The panel lights up but nothing happens.

That is not a power problem. Look at whether the panel is locked, whether the machine is in a mode, and whether water is arriving — a machine waiting for water looks idle.
