Moving fridge thermistor up = warmer??
Came across this link where the guy explains how moving the thermistor higher on the cooling fins actually creates a warmer fridge temperature. Which is the opposite of what the little sticker inside ...

Possibly, Some Control boards react differently. There is a resistance/Ohm signal from the Thermister and if out of normal range may cause malfunction of the Cooling cycle. On Norcolds, if you disconnect(unplug) the Thermister, it will cause a BOS cooling cycle. This causes the refer to alternate between cooling and shutting off at timed intervals. But, for a lot letting it hang down will cause 24/7 operation, until the refer Thermister gets cold enough if that is possible. Remember, The Thermister senses the FIN temp, not the air temp. The fin temp will be 10 degrees colder than the actual refer temp. No harm in trying, post what happens. Doug
Ive tried pulling the thermistor off the fins several times. I was hoping that would cause 24/7 cooling, since the probe would be reading air temp. But that doesnt seem to be the case, as my graph of the temps show it cycling off and on.
In desperation i installed a larger computer fan into my center ductwork. Im still fiddling around with the speed control to see if there is such a thing as "too much air". Im guessing that running it full blast would blow out the propane. Im on electric.
Also put a larger fan inside the fridge. I have 2 fans now that are double sided tape to the roof. With the probe laying in the drip tray im finally cycling between 36-38F.
That part im confused about is why isnt my fridge iceing up with the probe completely off? I was just gone for a few days and worried i was going to come back to frozen stuff. That happened weeks ago when i first pulled the thermistor off the fins. It did a big long cooling cycle down to 36F. But then rose into the 40s and cycled there. With the thermistor hanging in the air. Just didnt make sense.
