SPT WA-1230H Control Board
The SPT WA-1230H control board is made to operate everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all at once. HVAC systems will not run unless this board is in place and connected. The chosen circuit board must have a matching part number consistent with both the brand and specific model of the unit you have installed. You must be careful while searching to pick up a replacement control board due to so many small differences in brand and air handler types.
Some warnings of an ineffective primary control board
- There may be a fault code shown on the circuit board
- AC unit or heating unit cannot do anything period
- The HVAC system has to be turned off and back on often in order to continue running
