Review on Thetford 618548 Thermistor Assembly by Zack Frazier

This Thetford replacement thermistor fixed my Norcold RV fridge! The temperature in my refrigerator changed dramatically and the cooling fins were still covered with frost. After disconnecting the thermistor, I found that it was bad. Ordered a replacement, after 2 days everything is fine and works like new. When flushing your thermistor, look for something in the 9000 ohm range on most refrigerators. Mine was at 4000 ohms when it even checked in. Installation was easy as the plug was removed right inside the fridge. There is no more ice on the cooling fins and I keep the temperature constant.
