Tips to Replace a Light Switch

See light switch instructions by model below.

  • Light switch instructions do not come with light switches when shipped.
  • The switch is above the unit behind the grille on the 500 and 600 Series models.
  • Tools required are a Phillips head screw driver, T-20 Torx head screw driver, and pliers.
  • The outer grille frame may need to be removed for complete access to switches. See also, 500 and 600 Series Grille Removal and Installation.
  • 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.

For replacement light bulb information, refer to Sub-Zero Light Bulbs.

If the lights 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.
