After having replaced the drum support rollers twice in a roughly 3yr period, I realized something wasn't quite right, and indeed it wasn't. I had been ordering the wrong parts - I did use the online parts locator after checking, & double checking my model number. Apparently my older Whirlpool dryer has a somewhat ambiguous model number because the rollers that were shipped each time looked nothing like the originals. I realize that is not particularily uncommon - manufacturers often modify replacement parts. This time I decided to chat with Applliance Parts Pro's customer service department, and had a good picture of the actual model number label ready to attach to an email. The rep I spoke with was very accomodating, friendly and efficient. She had no problem giving me an email address to send the picture to. With in a few minutes she messaged me back with a part number for the rollers (which was different from my previous orders), part numbers for the front & rear seal assemblies, and the lint screen. I gotta tell ya, she was fast ! That means a lot to a 62yr young man who was born w/out the patience gene. At any rate, I received the parts, got the job done in a few hours, and I now have a dryer that runs every bit as smooth & efficient as it did when it was new.
I'd be remiss in my moral responsibilties if I didn't recommend always making sure you have provided as much accurate model, stock, run, or whatever else is on the manufacturers ID label BEFORE making a parts purchase.
Great company to deal with ! - just remember, as I was taught as a rookie electronics tech, "Always suspect yourself first, and if it's a really tough dog, walk away from it for a day or two" That line has served me well over the years.
