Dana J E San Marcos , CA March 17, 2015 Appliance: Whirlpool Laundry Centers LT7100XVW0 Whirlpool Washer Dryer Combo Lt7100xvw0: Dryer drum was beginning to stall occasionally. How to replace Dryer Idler Pulley. After shopping for a new Whirlpool Thin Twin Stack, Found appliance parts pros online and decided to take it apart to see if repair was a possibility. APPro's online instructions were easy to follow, in a couple hours it was apart, and I placed the order. Reg ground took a week from NY, so the laundry piled up that week. The parts arrived on Monday morrning, by afternoon the machine was running like new! The cause was the belt tensioner pulley had frozen. Replaced it, drum wheels,snap rings,drum belt. New cogs and seals for the Washing machine agitator were easy to replace and all worked great. $160 with shipping, saved us $1300 for a new machine. Also disabled annoying loud endcycle buzzer. Thanks APPro;s. we'll be back! Orig 1991 model. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
