Even on the minimum setting (Electrical), it freezes everything solid. I using an Infrared thermometer, I have found the coolest spot on the fins, and moved the bulb on the thermistor to that point. Doesn't seem any better. I'm willing to bet that the thermistor is dead (open). I cannot for the life of me find the part number for a replacement thermistor... It's a hard metal wire thermistor, not a flexible wire. I have looked through the service manual, but do not see a part listed... RV is Level. Have the fridge set to "1" right now. Have not tried the battery powered fan thing yet. Highly doubtful that the Snip-The-Tip replacement thermistor will work. If anyone knows the part number for this, I would be very grateful! Cheers!
