Haier CPN12XH9-E Control Board
Heating and cooling systems will not even run at all lest the circuit board is correctly installed. The control board is designed to operate everything including the gas valve, the igniter, all the sensors as well as the air circulator all at once. The correct control board must be compatible with both the brand and specific model of the unit in question. It is of utmost importance while selecting a replacement because of the wide variety of particular brands and their models.
