Sub zero 550 refrigerator light not working

My Sub Zero refrigerator light is not working. I checked the owners manual and it says the possible problem is the door was not shut properly, which may have been the problem, however I followed their instruction, waited the 1/2 hour & still no light. I also replaced 2 of the 4 bulbs...still no light

    I have the same problem--and when I replaced the bulbs, the light worked intermittently for a while. I think it is the door switch--how to repair/replace? There is no Sub-Zero repair person in my state, apparently.

    i had the same problem , remove the top cover where the compressor is housed . you will see two door switches the one on the left is the light switch , unplug the two wires going into the switch and place the 2 wire ends together if your light goes on its the switch . It cost me 12 $ canadian for one and its a easy repair anyone can do

First try to tightin the bulb, it has a seal and it's hard to drive it home. otherwise it could be the door switch.

I had the same problem with my sub-zero and finally resolved it (much to my wife's delight) by just replacing it. R&R was a lot simpler than having to work on it every time my wife had a problem.

We replaced all of the light bulbs in our 550 and the lights still do not work, any ideas?


Most likely light switch is bad. Could be light limit t-stat (prevents from overheating) and wiring problem too.

You probably have some food on the way. Unload the freezer and see if the door would close better. Looks like you have a warm air leak.
