# U-Line the interior light is not working

### Check whether the cabinet is cold

The maker's own row: if the unit is cooling and the light does not illuminate, it may be in Sabbath mode. That mode turns the interior light and the display off together and leaves everything else running, which is why a working appliance with no light is usually not broken.

### Two rows in the manual cover most of this

A light that will not come on when the appliance is cooling may be Sabbath mode. A light that stays on when the door closes wants the switch turned off if there is one, and the actuator bracket at the bottom of the door adjusted. Neither is a part and both are in U-Line’s own troubleshooting table.

### The switch is shared with the door alert

The same reed switch or plunger that tells the control the door is open is what turns the light on, which is why lighting problems and beeping problems arrive together. If both are misbehaving, that is one repair rather than two.

Sabbath mode

Light and display off, unit running. Held for a few seconds on one button to leave it.

The light actuator bracket

The maker's answer for a light that stays on when the door closes: adjust the actuator bracket on the bottom of the door. On glass models, check the reed switch.

The door switch

The same part that drives the door alert. When both the light and the alert misbehave together, this is why.

The LED strip or its settings

On the current controls brightness, color and the on-after-close timer are all settings, and one of them is the answer more often than a failed strip.

Check the cabinet is cold

The maker's own row: if the unit is cooling and the light does not illuminate, it may be in Sabbath mode.

Try the light button

On many models the light runs on a timer and can simply be off.

Watch the light with the door closing

A light that stays on wants the actuator bracket adjusted, which is the manual's own answer.

Check the lighting settings on current models

Brightness, color and the on-after-close timer are all settings, and one of them is usually the answer.

Two rows in the manual, and one of them is not a repair

What it usually means

No light with the door open

The light stays on with the door closed

Light works but the display is dark

### The light works but the display is dark.

That combination is not Sabbath mode, which takes both. Look at the display wiring — the manual's own first check is that both ends are firmly connected.

### Does BrightShield matter if it is off?

Not to the refrigeration. It is an antimicrobial light and the appliance cools perfectly without it, so it is worth knowing rather than worth panicking about.
