Lennox OF25-120R Control Board
The control board is designed to direct the gas valve, the igniter, all the sensors as well as the air circulator all at once. HVAC systems will not operate whatsoever unless this important circuit board is installed. The chosen circuit board must have a matching part number consistent with both the make and model of HVAC system. You should always be careful upon picking a replacement board due to variances between HVAC systems.
Simple warnings that your main circuit board is crapping out?
- The power to the system has to be reset often for the furnace or AC to kick on
- The HVAC system refuses to work at all
- There seems to be a fault code shown on the board
