But not there for that. It's got AL fault on control . I cnt find a thing about AL fault , dose any one know what it is .

if its a packaged unit- check the unit - if its an l box, theres a eng friendly pcb,if its a linea unit u need a kp02 controller to reset fault codes
what controller is it?

Have you checked gas pressure?? I recall this fault code many years ago and the only faults I have had is LP and no control supply which was down to a transformer with a little trip switch on the side which had tripped down to a faulty solenoid on 4 way valve

Hi Paul.
Have you any reference details for the package unit?
If it can be identified, I may be able to help further?

For a start pull that Lennox bubble sticker off it , I'll be you a pound to a pinch of sh1t it say's Carel under it..
Usually...
AL alarm active it should give the actual code beneath
But depending on Lennox parameters could be generic code
Check the filters, probably icing up.

We won't split hairs on this one Grizzly,
But knowing lennox it will probably be swings and roundabouts to reset the fooker.
