Sub-Zero Light Switch Replacement

If a light switch needs to be replaced, first determine the model. See also, Sub-Zero Serial Tag Locations.

Designer, PRO, and Undercounter Series Models:

Designer Series, Designer Wine Storage, PRO Series, and Undercounter Series units all require service to replace the light switch. 

Classic, 700, 600, 500, 400, and 200/300 Series Models:

Other models, including Classic (BI) Series units, can sometimes be repaired without a technician.

  • Side-by-Side units have light switches that are easy to replace without a service technician. Refer to the table below for part numbers and instruction sheets.
  • Over/Under unit refrigerator switches are easy to repair. However, the freezer light switch requires service to replace. See also, Over/Under Unit Freezer Light Switch Location.

Tips to Replace a Light Switch

  • Light switch instructions do not come with light switches when shipped.
  • Tools required are a Phillips head screw driver, T-20 Torx head screw driver, and pliers.
  • Make sure there is no power to the unit by turning off the circuit breaker.
  • The switch wires may be very tight depending on the age of the unit. Firmly pulling the wires by hand should remove them from the light switch.
    • If necessary, carefully pull at the base of the wire with a needle-nose pliers to remove the wire from the light switch.

500 and 600 Series Models:

If the lights still do not work after replacing the bulbs and the switch, service is needed to expertly diagnose and repair the product. Contact Factory Certified Service to schedule an appointment for repair.
