Thetford 618548 Thermistor Assembly Review

Well I can't comment on the durability of this item but it was fully operational, fit perfectly works perfectly. A third of the price of the website I first found this on. Many Thanks. Edit: The above was written on 4 Aug 19. Today is May 3rd, 2021 and we have been living in this RV the whole time. Everything with this part works great, no problems, has been running almost 24/7 for a year and a half. Very satisfied.

Problem solved for my 8 year old Norcold N611RT fridge which came OEM in my caravan. The freezer worked at -20 and the fridge at 25 degrees with severe frost on the ribs and frozen liquids. Before replacing the thermistor unit, turn off and defrost the unit. Now the money is in order: the freezer works from -10 to 0 degrees, and the refrigerator on average around 36. Very easy and quick installation - no tools required.

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…
