Unit showing a 91 fault code which is main blower fault. I have limited experience working on lennox and was hoping you guys could shed some light. Could anybody tell me the diagnostic process for this fault or give me a link to a service manual for this unit?
Thanks, nick

One of the best ways of getting manuals is to start with the manufacturers.

There is a manual on the Lennox website which you can download. (it's the wonder of Google ;))
