Samsung AD18B1C09 Control Board
Your furnace or AC will not run lest this board is configured and seated properly. The Samsung AD18B1C09 control board is created to control everything including the gas valve, the igniter, most sensors as well as the blower all at once. Be very careful when you choose a replacement due to the vast differences in systems. A matching board should be compatible with the brand and the model of the unit in question.
Major signs of an ineffective main circuit board
- There may be lit up error code shown on the board
- The unit refuses to initialize well
- The HVAC system has to be reset frequently for everything to run again
