My husband had an idea what it might be I googled whirlpool parts and your website came up, typed in dryer info easy-peasy ordered the pulley-Ldr ( and an extra belt) it was here in a couple days! The really great thing was my husband is pretty knowledgeable about appliances but I put the video on any way ?? Boy was he happy that saved him a lot of time he would have opened the back of the dryer to install part and the video showed it went in the front! Thank you for the video and all around good service
