I'm trying to work out what the "Compartment Heater" and "Compensating Thermo" are. Following the colors, the compensating thermo is inside a terminal box which is subjected to external room temperature. The back cover is not removable from the fridge without damaging the rear cover so I'm uable to find out where the Orange and Gray wires go.
It's definitely not part of the cyclic defrost system (which I plan on keeping). My intention is to cut a vent between fridge and freezer compartments and fan force the air (so the entire unit is at one temperature) and use a digital temp controller, am I right in assuming I should isolate/disconnect this heater regardless of where it is and what it does?
Edit: The cooling coil is in the freezer (fan forced) and the thermostat is in the fridge. The "Compensating Thermo" says "JP3 17" on it.
