If the dryer hasn't been used for a while,
there may be a thumping sound during the
first few minutes of operation.
• Is a coin, button or paper clip caught
between the drum and front or rear of the
dryer?
Check the front and rear felt seals for small
objects.
• Is it a gas dryer?
The gas valve clicking is a normal operating
sound.
• Are the 4 legs installed, and is the dryer
level front to back and side to side?
The dryer may vibrate if not properly
installed. See installation instructions.
Excessive vibration can also be due to
missing vibration pad under the motor
bracket. (See page 4-34).
• Is the clothing knotted or balled up?
When balled up, the load will bounce,
causing the dryer to vibrate. Separate the
load items and restart the dryer.
• Is the noise from the blower?
Lint balls in the blower wheel causes noise.
A cracked blower wheel will cause excess
noise.
• Is the vent connected to the dryer?
Dryer makes more noise with the vent off.
