CHANGE A SUB ZERO LIGHT SWITCH

Step one: Identify the Switch as the real problem.

Are your Sub-Zero lights not working? Have you checked out our tutorial on how to change a Sub-Zero light bulb? If you have, and your lights still do not work, this tutorial will fix your problem.

Step two: Identify your light switch.

Most Sub-Zero refrigerators use a universal light switch that can be found here. A picture of the switch is found below

Other models of Sub-Zero like the 501r and 501F, 601R and 601F use a rounded switch that is supplied directly from Sub-Zero. Find them on websites like Ebay. Here is one that is out of stock on Fixya.

Step three: IMPORTANT! CUT POWER TO UNIT.

Turn all thermostats to off, find your fuse box and cut all power going in and out of the unit. If you have an electronic model, hold the off button on the keypad. All lights and motors should go off. If you can, unplug the unit.

SERIOUSLY, SHUT THE REFRIGERATOR OFF AND CUT POWER TO THE UNIT. You will be shocked.

Step four: Remove Grill

Usually, three screws can be found on the frame of the unit. First remove these screws. If there are no screws, get on a step stool slowly pull the grill towards you, this will expose hooks behind the grill. Unhinge the grill and remove it from the unit.

 

Step Five: Remove light Switch Cover.

With a Philips head Screw Driver, unscrew the screws holding the light switch cover in. Sometimes you may need to use a 7/64 size hexagon key.

Step Six: Remove light Switch

All power should be cut to the unit at this point. If you do not know how to do this, stop what you are doing and call us at 800.200.2306.

The light switch and Fan Switch will now be exposed, The light switch has a white back, the fan has a black back. Remove the electrical wires from the white switch using a plier or your hands.

The light switch has a wedge on the right side, use a screwdriver to press on that wedge and bang on the top of the switch. Don’t be too delicate or the switch will not come out.

Press on the side of the switch.

Step Seven: Install New Switch

Before reconnecting the wires to the new switch you need to seat it. From the bottom, push the switch through the hole in the Sub-Zero where the old switch was. It should click. Once it is properly installed, re-connect the wires to the switch.

Re-install light switch cover and put your grill back on.

Allow power back into the Sub-Zero. Your lights should now work.
