Having a problem with the controls on my circa '97 12v Norcold DC-340D. I discovered items were freezing up in the fridge & when I tried to use the temp controls, the compressor would not shut off even when the knob was turned to off! I switched off the external power to the fridge & waited 10-15 mins with the door open until it warmed up a bit. It then started to operate normally.
Further troubleshooting finds that when this problem occurs, the clicking sound the temp control normally makes when adjusting the temp does not occur until I let the fridge defrost for a little while. Since it is the old style control inside the fridge (newer models the knob is external) I can't really tell what the mechanism is for switching power on & off thru the adjustment. I'm guessing it might be some piece of bi-metal that is freezing up or something.
Just wondering if anyone has had a similar problem or knows how the mechanism works so I can troubleshoot. Thanks!
