Sarah S Van Buren , AR August 01, 2014 Appliance: Whirlpool Dryer LER5636KT1 Whirlpool Dryer Ler5636kt1: The timer would not advance during dry cycle so would not turn off unless i turned it to the off position. How to replace Dryer Timer Control. I ordered a timer from Appliance Parts Pro, I watched the video on how to install it, I installed the timer and it works fantastic! I am now so glad that I can be busy and hear the buzzer go off to let me know that the clothes are now dry. Thank you so much Appliance Parts Pro! 11 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
