Review on Thetford 618548 Thermistor Assembly by Matt Larsen

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.
