Payne PH1ZNA042000AAAA Control Board
The Payne PH1ZNA042000AAAA control board is constructed to oversee everything including the gas valve, the ignition igniter, all the various sensors as well as the blower all in one unit. Heating and cooling systems will not even be able to function unless this board is properly connected to the unit. The selected board will need to be a match with your existing board and be compatible with both the make and model of the system you have installed. Be very careful when you choose a control board because of the many variances of certain brands.
