Lennox 13ACD-036 Control Board
Heating and cooling systems will not even activate lest the circuit board is accurately installed and configured. The Lennox 13ACD-036 control board is made to control everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. You must be careful while picking a new replacement board due to the many differences between particular brands and their models. The board you choose must have a matching part number consistent with the brand and the model of your Lennox 13ACD-036 unit.
Warnings to watch for in a failing primary control board
- Could be an numbered code lit up somewhere on the board
- Your HVAC unit will not function well
- The system board has to be turned off and back on frequently for it to run
