After unsuccessfully trying to change the blown light bulb I discovered that the plastic light socket had gotten so hot that it melted and permanently fused with the blown bulb. After my new socket arrived in the mail I just popped the temp control assembly out with a screw driver and removed the old socket and placed the new one in. Whole operation to 5 minutes.
The BIG problem was getting the old drip pan off. The bolt on top of the compressor was too long to allow the removal of the old drip pan. I removed the old drip pan by cutting most of it away with tin shears then cutting the remaining part of the pan around the bolt with a hack saw (taking care not to damage freon lines and raising the pan above the threads of the bolt so as not to damage the threads). I still had to cut half the bolt away with a hack saw by replacing the nut and cutting a third of the bolt away (above the nut), so the new pan would fit. Putting the new pan on was a breeze after that. It may be easier to just cut the bolt off altogether on top of the compressor and use the wire clips per the instructions supplied with the kit to install the new one.
Simple switch repair: Unplug fridge, pull down to remove switch assembly, slip contacts off. Reverse with replacement switch. HOWEVER, check first to see if the bulb filament might be broken, as this could cause the same symptom. OR in my case, the light socket connection was the culprit. Check that too before ordering a replacement switch.
