Product review (5 stars): Perfect fit replacement for Maytag dryer
So far so good!
We had the idler pulley wheel fail on our Maytag dryer model number SDG3606AWW.  For those unaware Whirlpool has purchased Maytag animana and is now manufacturing the replacement parts for these units so you will find multiple part numbers weather there are a Whirlpool number a Maytag number or an Amana number that are all the exact same part. For example, this part was sold under Whirlpool part wpy 54414 but it's also listed as part# AP6024203(likely the AP stands for Amana even though the product is a Maytag).
This machine is over a decade old and the only repairs it's required so far was a new belt a few year back and now this pully wheel. We decided to replace the belt (part# wp40111201 AKA part #  AP6009126) while we were in there as it had some cracks starting and we might as well save ourselves the hassle.
The pully did NOT come with either the washer or microscopic retaining clip but that's okay as our old ones were still in great condition.
It also doesn't come with installation instructions (super simple, washer threaded onto post of idler arm, add pully wheel, second washer, and then retaining clip) for the pulley itself or how the belt should be rethreaded onto the pulley wheel or the motor mount. YouTube will be your friend for putting the belt on properly, check multiple videos to find the one that works best for you.
This repair was relatively quick (for a gas unit you will be doing the threading blind, check youtube to see what I mean) and seems to have resolved the issues.
Just remember, always unplug your electrical connections and in the case of gas dryers like ours, simply shut off the natural gas valve at the back of the until as well until the repair is completed.
