Thanks, Steve, for your reply.
I have 2 of the either NT-12L or 16L ( I have not pulled them out yet to see the name plate). One has a screaming fan and the other is going that way. Both have the large yellow flame that is described as "bad" in the Suburban user manuals.
I also have one NT-24M that draws 15 amps on startup, so I am guessing the fan motor is locked up (no fan sound).
The plan is to pull each one and do a dis-assemble and inspection. I am an electrical engineer so the electronics should not be a problem - the mechanical I think I can mange as well.
The real gist of my original question is what does the "L" suffix mean? If I search the web there are no documents for the "L" versions, although I have have the user manuals for them.
I am looking forward to getting these babies out on my bench to see what is going on.
