Mitsubishi PCA-A42KA Control Board
The HVAC system will be unable to function without the board properly connected to the unit. The control board is designed to direct the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. The board you select will have a part number that will match both the brand and model of the system you have installed. It is imperative that you select wisely while choosing a new control board because of the wide variety of HVAC systems.
Some warnings your primary control board will need to be replaced
- The whole system needs to be reset many times a week for the thermostat to kick in
- Could be an error code being shown on the front of the control board
- The AC or furnace is unwilling to start well
