"If the thermister were not connected back to the control board, would the board somehow be able to sense the outdoor temperature?"
Geez would you stay out of my head! :) That is another exact thing that I asked and could not get an answer.
Some of the answers I have gotten for the problem:
From Dometic:
1. fridge not installed properly in the cabinet
2. the cooling solution gels/freezes in cold weather
From a tech:
1. thermister should be located next to the fins, not where it currently is (Dometic disagrees)
2. bad control board
As I said, no answers yet to the same questions you ask.
1.GEL only happens is sub 15 to 20 degree ambient temps. You then use a 60 watt light bulb at the rear cooling unit area to help the ammonia solution to not gel.
2. Thermister should ne ON the fins
3. in 37 years as a tech, I have NEVER had or heard of a refer NOT running in temps above 20 degrees ambient, but will when warmer than that.
4. Uninformed people think control boards always go bad. In the past 20 years(dometic), control boards rarely go bad. It is the other electronic items that fail, that the board relies on. Control boards will not cause a failure to run when cold and run when warmer.
5. A Temp Thermister can OHM out good but still be defective. SO, The temp Thermister is a cheap way to replace a suspect part. OR dunk the Thermister is a very warm glass of water and see if the refer starts in sub 30 degree weather. Doug
