My Whirlpool dryer timer will not advance in the automatic drying mode. The dryer continues to run and get very hot. I thought the problem was the timer so I replaced it . The problem still exists. The dryer works fine in the timed cycles.

(With no load in the dryer)
Disconnect the vent from the back of the
dryer (make sure the lint filter is clean) then
run it on automatic cycle for awhile.
Does the timer still stay in one place?

remove the little board and clean the contacts on it with a q tip and alchohol. shove it back in and see if that fixes it. This particular dryer(model number not located by the way just guessing from question) if I am right it has a small board mounted near the timer that powers the motor on the timer to advance it towards shut off only after no more moisture is sense inside the rear wall of the dryer by those sensors that mount on a black hump on back wall of the dryer. Just a guess.
