Greetings,
Both my wife and my gas dryer make a squealing sound when it runs. She is very sensitive to sound. If I can fix the dryer, I think that’ll take care of the other source. 
Is there a type of tensioner that adjusts belt tightness? Or what causes it to squeal? Everything else runs perfectly.
Thanks,
Dave
I cannot get your model number to come up, but if it is a basic Whirlpool built Kit Aid then changing out the belt, roller supports and tensioner should fix things.
