PROBLEM
Blower motor won’t start or won’t stay
running.
Dust emissions from clean air dis-
charge.
Insufficient airflow.
POSSIBLE CAUSES
Input power circuit is not operational.
Improper electrical wiring.
Starter overloads are tripped.
Blower rotation is running in reverse.
Hopper discharge is open to
atmosphere.
Ductwork volume control damper is
not properly adjusted.
Filter(s) is not installed properly.
Filter(s) is damaged.
Filter(s) is not seasoned or pre-seeded.
Dust particles are too fine to form
proper dust cake.
Blower rotation is running in reverse.
Loose or open bolt-on blower
compartment access door.
Open or leaking filter compartment door.
Ductwork volume control damper is
not properly adjusted.
POSSIBLE SOLUTIONS
Check input power to motor circuits for

Check and correct internal motor wiring
for proper connections based on the
incoming line voltage.
Check for proper motor starter overload
rating against full load amps on the
motor nameplate. Adjust or replace
overloads as required.
Check for proper blower rotation. Swap
