Lennox OF25-120 Control Board
The HVAC system will be unable to activate without the main control board installed. The control board is created to direct the gas valve, the ignition igniter, the flame sensor as well as the air circulator all together. Be very careful when you are deciding on a replacement because of the diversity of models within certain brands. The control board you choose will need to pair with the part number from both the brand and model of furnace or air handler you have.
What are the clues to watch out for to know my HVAC circuit board really needs to be replaced?
- The control board has to be turned off and back on often for the furnace or AC to kick on
- There may be lit up error code being shown on the board
- System is unable to function whatsoever
