International Comfort Products PGAA42C1K1 Control Board
The International Comfort Products PGAA42C1K1 control board is designed to command the gas valve, the ignition igniter, all the various sensors as well as the air circulator all together. Your furnace or AC will not run at all unless the control board is properly connected to the unit. You must be careful when you decide to replace your control board because of the wide variety of systems. The control board picked will have a part number that will match the brand and the model of HVAC system.
Key clues of a poorly working main board
- The system has to be turned off and back on all the time in order to run
- The heating and cooling system will not start at all
- Could be an numbered code indicated directly on the board
