Lennox 90UGF Series Control Board
The control board is constructed to direct the gas valve, the igniter, all the sensors as well as the air circulator all together. Your system definitely will not be able to function unless the control board is in its proper place and configured for your unit. The brand of board you choose should be compatible with both the make and model of air handler system you have. It is of utmost importance when choosing a control board due to differences in heating and cooling systems.
What are the clues to watch out for to know my Lennox control board is about to go out?
- Everything has to be reset often in order to run
- There seems to be an error code shown directly on the circuit board
- AC or heating system cannot initialize well
