Product review (5 stars): Exactly what my Sub-Zero 611 needed!
I called Sub-zero because my refrigerator light and the panel was not lighting up. First, i changed the light bulbs to no avail. I called Sub-zero and i guess this is a common problem because the woman told me i have two options. Have a technician go there (pricey) or fix the switch myself. She was kind enough to send me directions via email as well. Reading other Amazon reviews i thought this was going to be pretty easy. It was if you have the "star" screwdriver. I had no problem unscrewing the panel or the cover, it was just the flap covering both of the switches. In addition, it was a bit hard to pull the wires out (bluish white and red) but once you do its smooth sailing from there. I popped the new one back in. Screwed everything back on and guess what? My refrigerator is glowing. :) The panel and the inside light up. I am very thankful as its been years since it has been working (don't ask). Thank you to all the reviewers here that offered their advice as well.

PS - For my refrigerator it was the left switch that controls the light. The right one controls the fan.
