Haier HC36D2VAR Control Board
The HVAC system will be unable to be able to function lest the circuit board is in its proper place and configured for your unit. The control board is created to control everything including the gas valve, the ignition igniter, the flame sensor and the blower all together. The board you select will have to match part numbers both the brand and specific model of furnace or air handler you have. It is of utmost importance while picking a new replacement board due to so many small differences in certain brands.
Elements of a poorly working main circuit board
- There seems to be flashing code shown on the board
- System is not able to do anything well
- The HVAC system needs to be reset often for the thermostat to kick in
