Dometic Fridge Question - just curious
I have a Dometic 3 way fridge which, despite its vintage, 1995, works wonderfully well in all 3 modes, but I have a question, mostly out of curiosity.
In Indiana last month with temperatures in the high 30's (C) and overnight lows in the mid 20's, I had the thermostat cranked to 6 to maintain a reasonably cool fridge temperature, and the frozen stuff frozen. In the Alberta Rockies this week with highs in the mid 20's and lows perhaps 10, I had to turn the thermostat way down to 2 or 3 to avoid freezing temps in the fridge. I generally need to adjust the setting accordion to the outside temperature. The thermostat seems to function more as a power, be it electric or propane, input controller than an actual thermostat (which would set and attempt to maintain a given temperature regardless of the ambient temp.
So, no operational problems at all, but does anyone know if the dial is really a thermostat, or does it modify the power input?
