I have never before seen a bulb with the filament intact not light. If the bulb's filament seems intact, screw the bulb into a known working lamp and see if it lights. When screwing it back into the socket in the fridge, it takes a bit of extra effort to fully seat (until it does, it won't light!). For replacing the switch, I unplugged the unit, used a paint scraper and worked it under the switch bezel from the right side. A bit of moxie, and the switch came out. The replacement switch had a different spade contact spacing than the original. I used a pair of scissors to cut the rubber bridge between the two switch wire connectors so I could connect to the new switch. In the end, it turned out to be the bulb. NOTE: The Model TC18KL is _not_ listed! What I finally found that the number "P7803211WL" on the sticker is actually a manufacturing code. Found this out by searching, and Sears' part search came up with matches.
