Sorry you're dealing with that after putting in a new unit and board. A few things to check:
1. Let it run on AC for a few hours, then feel the boiler area and the top condenser fins. If the heater side is hot but the condenser stays cool, the cooling unit isn't circulating, and that points back to the unit itself. 2. Make sure the heaters are fully seated in the boiler tube and the fridge is level. Absorption units are picky about level. 3. Check that the insulation and foam seal around the cooling unit went back in tight.
The 634747 has been replaced by the Nordic 6610 cooling unit for the 1200/1210. If you want a second set of eyes, our tech service can walk through it with you.
