Please help us solve our problem. The blower on our gas dryer (#41759012890) makes a loud whining sound when in use. Is there any way to quiet this? Can we substitute a different (quieter) blower and if so, which one? Is there any type of padding or quiet housing we can put around so the sound won't come through the dryer exhaust? We've already replaced the motor and the blower once. Thanks for your help.
