Lennox 13ACD-018 Control Board
The Lennox 13ACD-018 control board is made to control the gas valve, the igniter, all the various sensors as well as the air circulator all in one unit. The HVAC system will be unable to operate lest this board is correctly installed. The chosen circuit board must have a matching part number consistent with both the brand and specific model of HVAC system. You must be sure upon picking a replacement board because of the diversity of HVAC systems.
Easy warnings to watch for in a failing Lennox control board
- The furnace or AC refuses to go well
- Power to the circuit board has to be turned off and back on all the time for the thermostat to kick in
- System has some sort of error code indicated on the front of the control board
