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 ...

1. Norcolds have a "defrost" cycle built in for the bottom part of the refer. What Norcolds do is, every 48 to 54 hours the refer shuts OFF for about 2 hours to allow the evap fins to defrost any ice build up
2. ICE is NEVER a good thing on Evap fins. ICE is a insulator and will yield warmer temps in the lower section.
3. There is NO reason to attempt to move the Thermister probe end around. It does not make any difference at all
4. AS to hanging in the air. Remember I told you when you DISCONNECT a Norcold Thermister it puts the refer in BOS mode. As I stated, I am not sure how the refer sensor system would react with the Sensor OFF the fins. I suspected with out a normal OHM return signal it would go into BOS mode. Your testing seems to confirm that.
5. At this point if I had your refer in the shop. I would verify the 2 cooling fans operate and would hot wire both 120 elements for 24 hours. After 24 hours with the fans running, if the refer failed to get below 36 to 38 degrees-----Your CU is bad. Doug
PS, The defrost cycle only happens when the refer is left ON continously. If you turn the refer OFF and ON before the first 48 hours is reached the timer resets. Some fulltimers(that know the defrost cycle) get in the habit of turning the refer OFF and ON every day to prevent that defrost cycle.
