CAUSE
REMEDY

Accidental damage to the fan blade can change the
dynamic balance. Damaged fans should be replaced.
Adjust basket clearance.
Tighten set screws. Make sure sheaves are in proper
alignment.

other causes that may prevent damper from opening.
Check duct work for lint build-up. Check installa-
tion sheet to insure that duct work and make-up air
openings are adequately sized. Check exhaust
outlet. If a screen has been improperly installed on
the outlet, it may be clogged with lint or frozen over

outlet. Vacuum within dryer drops to .09 inches of

sheet metal screw in the front panel of dryer and
inserting the rubber tube of the vacuum gauge into
screw opening.
