Lennox XC14-030 Control Board
Heating and cooling systems will not even activate unless the control board is installed. The control board is made to command everything including the gas valve, the ignition igniter, all the sensors and the blower all together. The board you choose should have part numbers that match both the make and model of HVAC system. Be very careful upon picking a replacement board due to the vast differences in brands, models and types of systems.
Simple signals your Lennox control board has little life left
- Entire unit is unable to do anything at all
- Power to the control board needs to be reset quite a lot for it to run
- Could be an error code being shown somewhere on the circuit board
