Lennox OF24-105 Control Board
The HVAC system will be unable to operate lest the main control board is properly connected to the unit. The control board is made to oversee everything including the gas valve, the ignition igniter, all the sensors as well as the blower all at once. Be very careful when you decide to replace your control board due to differences in systems. The board you select should be compatible with both the brand and specific model of the system you have installed.
Easy warnings your main board will eventually need to be replaced
- Could be an a strange code lit up somewhere on the circuit board
- The entire system refuses to run whatsoever
- The system board has to be reset all the time in order to operate
