How to Change a Sub Zero Light Switch

Please turn power off to your unit at the fuse box before operating on your Sub-Zero.

Tools Required: Phillips head screw driver, needle nose plier.

Step One:  Remove the grill from your Sub-Zero.

Removing the grill from your Sub-Zero is usually accomplished by first removing screws above doors on the frame of the unit. Once the screws are removed you can pull the grill forwards and remove any springs. If you have a wooden grill, you must first remove the wooden trim by pushing up on it and pulling the bottom towards you. Next, you remove screws on the frame above the door and usually two screws on the upper right and upper left of the bracket that holds the trim.

500 series and 600 series Sub-Zero’s are pretty similar in how they operate lights. They use a small light switch that can be purchased through ebay.

Step Two:  Locate the light switch shroud and remove the screw holding it in.
