Samsung AQB18J6WC Control Board
Your air handler will be unable to operate whatsoever lest this board is properly connected to the unit. The control board is made to direct the gas valve, the igniter, all the various sensors as well as the blower all in one unit. The board you choose is supposed to have a part number that matches both the brand and specific model of air handler system you have. You must be sure upon choosing a board as a replacement due to so many small differences in particular brands and their models.
Key clues of an unhealthy control board
- Entire unit declines to work at all
- The control board has to be turned off and back on many times a week for the system to operate once again
- There may be a certain error code appearing on the circuit board
