Lennox G26Q4-75 Control Board
The Lennox G26Q4-75 control board is constructed to regulate the gas valve, the ignition igniter, all the sensors as well as the blower all at once. Heating and cooling systems will not even be able to function lest the circuit board is accurately installed and configured. The control board you choose will have to be compatible with both the make and model of air handler system you have. It is of utmost importance when you choose a control board because of the many variances of certain brands.
What are the clues to watch out for to know my main board is failing?
- Could be an some sort of code instantly appearing somewhere on the circuit board
- System is not able to operate well
- The entire system has to be turned off and back on rather frequently for it to kick in
