Topics:

• How the control panel in refrigeration and freezer units is lit
• Control panel lighting for 600, 700 Series, IC-27, and Classic series (BI) units
• Are the control panels in a Sub-Zero back-lit

Answer:

600, 700, IC-27R/F, and Classic series (BI) Unit displays are back-lit by the interior light bulbs.

• This does not include 700BF, 700BR, and 700BC models. Their panels are not backlit.
  • Service is required if 700 Series base model control panels are dark.
  • Control panel needs to be replaced.
  • Contact Factory Certified Service to schedule an appointment for repair.
• If replacement light bulbs are needed, refer to:
  • Sub-Zero 500 and 600 Series Refrigerator Light Bulbs 
  • Sub-Zero 700 Series Light Bulbs
  • Sub-Zero Classic Series (BI) Light Bulbs
  • Sub-Zero IC-27 Model Light Bulbs
• For dispenser units, see Sub-Zero Vertical Control Panel Light Bulb Replacement.
• Control is not affecting by the light bulb being out, and will work normally.
