Lennox 13ACD-048 Control Board
The control board is constructed to regulate everything including the gas valve, the ignition igniter, the flame sensor as well as the blower all in one unit. It is impossible for your furnace or air handler to even be able to function lest this board is configured and seated properly. Any control board you choose will need to pair with the part number from both the brand and model of your heating and cooling system. It is of utmost importance when you choose a control board because of the many variances of models within certain brands.
Signals your primary control board has little life left
- The entire system is unwilling to start well
- Could be an a strange type of error code indicated on the board
- The entire system has to be reset all the time for it to run correctly
