Norcold 838EG2 sporadic wide temperature fluctuation.The fridge temp ranges between 32F -48F, regardless
I have a Norcold 838EG2 that for the past several months has been experiencing wide temperature range in the fridge (32F-48F), regardless of time of day or outside temperatures. The refrigerator has been stationary since 2010, it is spot on level, the Lpg source is correct, the back of the unit has been cleaned, there is plenty of airflow, the flame is good and strong, and it has had the power supply board recall performed. The temperature sensor is NOT the clip-on thermistor, but a tube, which appears to be in good condition. Any suggestions as to how to fix this fridge? Or is it time to put it out to pasture?
