Lennox 12CHP036 Control Board
The Lennox 12CHP036 control board is constructed to control the gas valve, the ignition igniter, all the sensors as well as the blower all together. HVAC systems will not run at all unless the control board is hooked up and is correctly configured. The board that you will choose will have to be compatible with both the make and model of furnace or air handler you have. You must be careful while searching to pick up a replacement control board because of the wide variety of heating and cooling systems.
Indications your main board is failing
- There seems to be a strange type of error code lit up on the circuit board
- The HVAC system has to be reset many times a day for the system to operate once again
- The AC or furnace declines to initialize whatsoever
