Ok, let’s see if we can get this mapped out and fixed:

Your FURNACE has 4 wires, should be 2 blue, and probably a red and yellow.

The 2 blue are the thermostat connections, the other two are 12V positive and ground.

The 2 “sets” of stranded wires: use an OHM meter and test for 12V. That will be your power to the furnace, if the other “set” of stranded wires DONT have 12V, then test for continuity from those to the fridge. If you have continuity there is your 12V power to the fridge.

The 2 “single” wires are the thermostat and hook to the 2 blue wires from the furnace.
