Rick K Richton Park , IL May 23, 2023 Appliance: Model WHIRLPOOL After 20 years of running great, the dryer started to take forever to dry and timer would not advance in auto mode. Took apart, ran tests, cleaned years of lint buildup in the entire dryer, and replaced gaskets and venting. Thanks to your videos and parts availability, this would not have happened.
