Customer Questions and Answers for Dryer Drum Support Roller by Whirlpool

Hello Gary, You either have a drum roller 12001541 failing or the idler pulley WP6-3700340 is failing. I normally try to replace all of the above at the same time. Since they all last about the same amount of time, the others are not long before failure. Be sure not to use any wet lubricant inside the dryer. If you want to lubricate anything in there use corn starch or baby powder. Also, be sure to remove and trash any metal washers used on the drum rollers. The fiber washers come with the drum rollers for the purpose of eliminating the metal ones that contribute to normal operating noise.
