down to the OFF position.

POSSIBLE CAUSE
TO CORRECT
Inoperative idler spring.
• Remove lower access panel. Set dryer to normal cycle and
allow it to heat to operating temperature. If the belt
vibrates as it rotates around the cylinder, the idler arm is
making the noise. Replace the idler spring. Refer to
Figure 41.
POSSIBLE CAUSE
TO CORRECT
Inoperative blower housing.
• If the abnormal operating noise is loudest at the vent exit,
the problem is originating from the blower housing.
Replace the current housing and cover. Refer to Figure 42.
