A defective Thermister will still OHM (test) correctly. Are you positive you replaced with the correct Thermister? There are 2 Thermisters for the 1200 series. Make sure you get the one for your Model/Serial number. Thermisters rarely fail. I would try one more thermistor and if the refer fails again then replace the Control board. What work has been done on the refer? Have you had the rear fans and fan tstat ever replaced? IF the fans are more than 4 years old, I would replace them and the fan tstat and run a jumper bypass from the fan tstat at this point. IF the fan tstat and/or the fans are not operating WHEN they should THAT will cause a NO CO. I have rarely had a thermistor cause a NO CO trip. Doug
