Lennox G26Q2-50 Control Board
The control board is made to command the gas valve, the igniter, all the sensors as well as the blower all together. Most systems will not run without the control board in its proper place and configured for your unit. You must be careful when you choose a control board due to variances between heating and cooling systems. The brand of board you choose is supposed to have a part number that matches the brand and the model of HVAC system.
Important clues of an ailing main board
- The system board has to be turned off and back on a lot for it to work
- System has a certain error code being shown somewhere on the circuit board
- Your HVAC unit is unable to do anything at all
