Since it works great on AC, the new cooling unit is fine, and the problem is on the LP side. Make sure the flue baffle got reinstalled in the new unit, the burner is centered under the flue, and the burner and orifice are clean. A missing or misplaced baffle is a common cause after a cooling unit swap. The original 1200 burner (629013) is discontinued. See our 1200/1210 burners and orifices for current options.
