WRT108FFDM00 Whirlpool Refrigerator - Instructions

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.

unplugged the fridge removed the shelf, remove the rear wall to access the motor removed the 2 screws holding the motor and unplugged motor from harness, then unplugged the groung wire .then put it back together up and running in 15 mins.

After plugging in the new relay to no avail. I replaced the thermostat. That fixed the problem.
