Stops blowing warm 20 minutes before cycle ends
Have an old Kenmore dryer that stopped blowing warm but would still tumble and blow cool air. Recently ordered and replaced the heating element which did start the machine blowing warm again, but it starts going cold air 20 minutes before the cycle ends leaving the clothes damp.
In my case the problem was the dryer timer which I purchased online from Amazon for $89.99 from Repairwares. Received it in two days and installed it in under 10 minutes. Helped reduce the cool down cycle from 20 minutes to 5 allowing the clothing to fully dry and even improved the fluff cycle which was not working properly prior to changing this part.
