Sub-Zero Interior Lights Turned Off
- No lights or lights not working in the refrigerator or freezer
- Door ajar or left open and the lights turned off
- Lights turn off while product was being cleaned or loaded with food
- Lights went out or do not turn on
If the lights are out inside a refrigeration product, use the following steps to try resolving the issue before calling for service.
- Verify the unit is turned on and power is going to the product.
- If accessible, confirm the product is plugged into the electrical outlet. For models with a grille at the top, removing or flipping the grille up may provide access to the power outlet.
- Turn the home circuit breaker to the unit off for 30 seconds then back on again. Retest the unit operation.
- If temperatures are faint on the display, the unit may be in Sabbath Mode. See Sabbath Mode Information for instructions on exiting Sabbath Mode.
- If the door is open for a long time, the light terminator feature can turn off the lights. See Light Terminators for steps to reset.
- If the controls do not illuminate, see Sub-Zero Control Display Is Dark for troubleshooting information.
Only some models have an accessible door switch. To determine a unit model, refer to Sub-Zero Serial Tag Locations.
