Lennox 13ACX-048 Control Board
The control board is made to oversee everything including the gas valve, the ignition igniter, all the various sensors as well as the blower all together. Your system definitely will not operate without the control board correctly installed. A control board that you have chosen should match both the brand and specific model of your heating and cooling system. You should always be careful while picking a new replacement board due to variances between models and types.
What red flags are there that my HVAC circuit board is not working properly?
- The board has to be turned off and back on quite often for the system to operate once again
- Could be an some sort of error code directly somewhere on the circuit board
- Your system is unable to go period
