How to replace Dryer Drum Support Roller Assembly. There are 4 rollers that support the dryer drum while the belt is running. One of the rollers had frozen. I found AppliancePartsPros on the internet. They were reasonably priced on the replacement roller. What was exceptional with the site is that there are videos that show you how to replace the part, very informative videos. I had never taken a dryer apart but it was easy after viewing the instructions. The repair took 45 minutes to disassemble and assemble back after replacing the part, which was very simple. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
