Lennox OF25-105 Control Board
The Lennox OF25-105 control board is created to regulate the gas valve, the ignition igniter, most sensors as well as the air circulator all together. Your system definitely will not operate lest the main control board is properly connected to the unit. You should always be careful upon picking a replacement board due to variances between models within certain brands. The board you select should match the model number with both the brand and specific model of your Lennox OF25-105 unit.
What you should see if the primary control board is not working properly?
- The system has to be powered down and back up often for it to work
- The AC or furnace is unwilling to run well
- System has lit up error code instantly appearing on the board
