How to Troubleshoot & Replace Whirlpool AP5983729 / 661570V Dryer Drive Belt

Ordered parts from Appliance Pros, and watch the install videos. I have ordered form appliance pros in the past and was confident they would show me the right parts to ordered. The install videos are an excellent tool. 

Replaced pulley spayed it with w-d40 and works perfect 

Take apart back of dryer and replace parts. Easy fix! 

Ordered new part and googled repair 

I found AppliancePartsPros' video on you tube for the drum roller repair. I first replaced them and it took care of the "clunking sound on startup. Unfortunately the squeeling didn't go away. I followed the first video again and took everything apart. By hand rolling the idler pulley, I could hear the squeeling noise. I ordered the parts and decided to replace the belt while I had intake apart again. Thebparts showed up the next day which was awesome shipping time. I installed them and the dryer sounds like it is brand new again. The website and how-to videos are great. I always buy from this website and will always recommend it. My wife is a big fan too! Happy wife, happy life! 

I have an old Kenmore Elite gas dryer which was extremely noisy. Research brought me to the conclusion to replace the drum support rollers and the idler pulley assembly. Instead of just replacing the idler pulley I decided to purchase the assembly since it had a new shaft which I was concerned was worn too. I found a video for my exact model elsewhere. My model is much older than those included on this site. When replacing the drum support rollers I applied some Super Lube to the shafts. I did the same for the idler pulley shaft too. I bought four Tri-Rings just in case I needed them. I did not since the ones there were fine and did not break. I also bought just the idler pulley just in case I wanted to go that route and replace just it instead of the assembly. Upon inspection of my assembly I did not like how the pulley was spinning so I decided to replace the whole assembly. In my order I also ordered a relay but that was for a different problem with the dryer. My dryer was turning off intermittently before the cycle was done. My specific symptom was that when the dryer quit if I held in the start button the drum would spin but once I released it it would stop. There are two relays used (same part) and one of them is for the motor. Replacing that one solved that problem. 

With a little help from their video and the Right part the first time, my repair was a breeze! And the part in my hand overnight,priceless! 

Removed rear cover, determined idler pulley was not rotating freely, removed pulley, replaced pulley with replacement part, reassembled, test run. Works fine. 

Took whole dryer apart and made repair 

Replaced drum rollers, belt tensioner roller and belt at same time.
