Haier HC30D2VAR Control Board
The control board is constructed to direct everything including the gas valve, the ignition igniter, all the various sensors as well as the blower all at once. It is impossible for your furnace or air handler to even run without the main control board accurately installed and configured. You should always be careful upon choosing a board as a replacement due to the many differences between HVAC systems. The selected board will have a matching part number that will fit in both the brand and specific model of HVAC system.
Hints your Haier control board is in need of replacing
- Your HVAC unit declines to work period
- Power to the control board has to be reset habitually for it to work
- There is numbered code lit up on the front of the control board
