TM
Operations
and Maintenance Manual.)
a) Turn off the main power supply to the furnace.
b) Loosen and remove the two thumb nuts securing the blower / flipper assembly to
the large air tube, and remove the blower / flipper assembly.
c) With a small brush, scrape any dust or residue that has accumulated on the fins
of the blower.
d) With a scraper or brush, remove any residue built up on the flipper assembly.

perhaps there is dust or soot built up on the flipper, or some other obstruction not
allowing it to close tightly.
f) Securely fasten the blower / flipper assembly back to the large air tube ensuring
there are no air leaks.
