How to Troubleshoot & Replace Samsung AP5325135 / DC97-16782A Dryer Drum Support Roller Assembly

The amazing video on the AppliancePartsPros.com web site, walked me through the process of taking my dryer apart and replacing the rollers. The only problem I had was that I thought it was one defective roller, only 3 years old, but it was two. When I ordered the second roller they held up my order thinking it was a duplicate. Just order two or even four to start with. Lesson learned, if one is bad, two are bad. It isn't that much work to take it apart but I should have ordered two to start with. 

Disassemble dryer per video. Discovered idler pulley(tensioner) melted/bearing seized. Checked drum support roller (no wear or noise present). Vacuumed out dryer and cleared dryer vent pipe (surprisingly little lint present inside dryer cabinet) Installed new idler assembly and belt & reassembled dryer. 

While visiting with my daughter, who lives on the edge of Orlando, she mentioned her dryer would periodically make screeching noise, then quiet down. It's been 30 years since I had a dryer apart, but what a wonderful thing YouTube is. I was pretty sure it was either a belt and/or belt tensioner. I placed an order for those items to be delivered to Daughter #1's house in a rural area of FL and it took 6 business days. I went down to Daughter #2 and dismantled the dryer and discovered one of the rear drum support rollers was completely shot causing the tensioner to dig into axle and belt burnt a couple of grooves on each side of tensioner. Working up order for the support roller and discovered tensioner bracket is not available without a roller, so ordered it, too. I recommend ordering the assembly, not just the tensioner roller. Roller in the assembly has roller bearing, single tensioner roll is a fixed bushing. While checking out I discovered it only cost $3 more for next-day delivery vs standard ($9.95 vs $6.95) and it would be $14.95 to the more rural address. Parts arrived the next day as advertised. The dryer assembled with no extra bits leftover and it's working as it should. 

Replaced all rollers, belt idler, and belt- no more noises. -paid for 2-5 day shipping but parts arrived overnight-was very pleased. 

Took apart dryer, determined that the idler assembly and drum support roller assembly needed repair. Ordered parts from Appliance Parts Pros, installed parts, put the dryer back together and the dryer works. Instead of paying $700 for a new dryer, $90 in parts did the trick. 

Ordered part from appliance parts pros and made repairs. 

Ordered parts online, came in when expected. Replaced roller 

After doing research online, found the parts that lined up with my problem. Also found a GREAT instructional "how-to" video which gave me the confidence to try it myself. I am NOT a mechanical guy. The model in the video was electric, and my dryer is propane gas, but the location of the parts I had to replace were the same for both. The only difficulty I had was that the dryer is stacked on top of the washer (connected), and since I did NOT want to separate the two, it was a little heavier to slide the double-unit around so I could access all the screws, etc.. But it worked fine. 

I disassembled the dryer to get to the failed part. I checked and decided to also replace the belt and a drum support roller. The order arrived on the day specified and within an hour the new parts were installed and the dryer ready for duty. My wife said that the dryer works better then when we first got it. 

Googled symptoms (squealing, finally no drum rotation). Started off with a youtube video to see how complicated the repair is, or whether special tools are required. Videos showed simple repair with common tools. Disassembled and located faulty parts. Ordered parts from AppliancePartsPros.com because overall - especially shipping - *much* less expensive than Samsung. Parts arrived in two days. Installed in less than an hour.
