The smoke unit on my Lionel Legacy 6-85021 SW7 had been working fine. Now, however, when I turn the smoke on, the fan starts but then quickly stops as the cab light flashes two blinks, which the owner's manual says is the diagnostic code for a smoke element problem.
Everything looks fine inside the smoke unit--for whatever that's worth--other than a small amount of charring on the batting. I cut the charring off, repacked the batting, and, I'm not sure why, the smoke unit began to work for a minute or two--but then went back to the two blinks.
Would the problem definitely be the element, as indicated by the diagnostic code? How would I test that to be sure? Could the issue possibly be with the fan motor instead of the element?
