International Comfort Products PGAD24B1K4 Control Board
The control board is designed to control everything including the gas valve, the igniter, most sensors as well as the blower all in one unit. HVAC systems will not run at all without the main control board properly connected to the unit. A replacement board will have a matching part number that will fit in the brand and the model of the system you have installed. You should always be careful upon choosing a board as a replacement because of the wide variety of systems.
Signals your control board will eventually need to be replaced
- Your HVAC unit is unwilling to start at all
- Could be an a certain error code indicated directly on the board
- The HVAC system has to be reset many times a week for the system to continue working
