Haier HR18D2VAR Control Board
Your furnace or AC will not be able to function without the board installed as it should be according to the manufacturer. The control board is created to command everything including the gas valve, the igniter, all the various sensors and the blower all in one unit. You must be sure when choosing a control board due to differences in systems. The correct control board will have a matching part number that will fit in both the brand and specific model of the system you have installed.
What are the indications that my primary control board is failing?
- The unit declines to start period
- Power to the control board has to be reset quite often for everything to run again
- There seems to be a fault code suddenly appearing somewhere on the board
