Samsung AM18A1C09 Control Board
HVAC systems will not be able to function lest this board is properly connected to the unit. The control board is constructed to control everything including the gas valve, the ignition igniter, most sensors and the blower all in one unit. It is of utmost importance when you are deciding on a replacement because of the diversity of models within certain brands. The brand of board you choose is supposed to have a part number that matches both the make and model of HVAC system.
Red flags of a deteriorating control board
- The HVAC system has to be powered down and back up many times a day for it to work
- System has a flashing error code shown directly on the board
- Heat or AC unit is unwilling to function well
