Lennox OF24-120 Control Board
Most systems will not activate lest this board is configured and seated properly. The Lennox OF24-120 control board is constructed to regulate the gas valve, the igniter, most sensors as well as the air circulator all at once. The board you select will have to be compatible with the brand and the model of your heating and cooling system. You must be sure upon picking a replacement board due to so many small differences in models and types.
How do you know when your control board is crapping out?
- Could be an a type of code indicated somewhere on the circuit board
- Entire unit ceases to run well
- The board has to be powered down and back up habitually for the system to operate once again
