My Whirlpool Duet dryer started making a rattling noise. It's coming from the back of the dryer around where the duct attaches. It is not constant but pretty frequent. We stuck something under the duct at the connection point which has minimized the noise a little, but has not stopped it. I'd hate to pay $100 for the service call for them to take the duct off and put it back on, but I'm also a little nervous about doing it myself. Any thoughts of what it might be? Thanks.

Remove the vent hose from babk of dryer and look inside and see if anything is in there to cause this noise. Can't be much causing this noise. Bet we can figure it out. Post back
