Lennox XP19-030 Control Board
HVAC systems will not be able to function lest the circuit board is correctly installed. The control board is made to oversee the gas valve, the ignition igniter, all the various sensors as well as the blower all together. You must be careful while searching to pick up a replacement control board due to the vast differences in models within certain brands. The board you choose will need to pair with the part number from both the brand and specific model of air handler system you have.
What are the signs that the Lennox control board is almost dead?
- There may be some sort of code randomly appearing somewhere on the circuit board
- Everything needs to be reset all the time for it to run correctly
- System declines to operate at all
