Haier HPR09XC5 Control Board
Your air handler will be unable to be able to function without the board accurately installed and configured. The control board is created to operate the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. The correct control board will have to be compatible with both the brand and specific model of HVAC system. You must do some research when choosing a control board due to the many differences between HVAC systems.
General indicators that your main board is dead
- The unit is unwilling to initialize properly
- The HVAC system has to be reset rather frequently in order to continue running
- Could be an a strange type of error code showing up on the board
