Haier HSU-12C03 Control Board
Most systems will not be able to function unless this important circuit board is in its proper place and configured for your unit. The control board is constructed to oversee everything including the gas valve, the igniter, most sensors as well as the air circulator all together. The selected board will have a matching part number that will fit in the brand and the model of your heating and cooling system. You should always be careful when choosing a control board due to the many differences between models and types.
Clues your main board will need to be replaced
- There seems to be an error code showing up on the front of the control board
- Entire unit ceases to initialize at all
- The power to the system has to be powered down and back up all the time for the furnace or AC to kick on
