Topics:

• No lights or lights not working in the refrigerator or freezer
• Lights flicker or do not turn on when door is opened
  

Troubleshooting:

If the lights are out inside a refrigeration product, first refer to Sub-Zero Interior Lights Turned Off for initial troubleshooting steps.

1. Wiggle the light switch back and forth and push in and out to make sure it is not stuck.
   • Single door models have one switch; two-door models have two switches.

2. For freezer sections, the light switch may be frozen. Defrost the unit if possible. See Manually Defrost a Sub-Zero for instructions.
3. If the switch is stuck, it may need to be replaced. Contact Factory Certified Service to schedule an appointment for repair. 
   • Do not use lubricant on a stuck switch.

If the switch is not stuck and lights still do not work after completing the steps above, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
