Lennox G40DF-48C-090 Control Board
The HVAC system will be unable to be able to function without the main control board configured and seated properly. The Lennox G40DF-48C-090 control board is made to control the gas valve, the igniter, most sensors and the blower all together. You must do some research when choosing a control board due to variances between models and types. The selected board must be compatible with both the brand and specific model of furnace or air handler you have.
Signals your control board should need replacing
- The entire system ceases to work well
- The board has to be turned off and back on habitually for the system to operate once again
- When turned on, there is some sort of error code being shown somewhere on the circuit board
