[Ken]

By sticking do you mean open or closed. The dexter stack air flow switch flap is actually too far away from the hole when the dryer is at rest and as a result there are times when it may not pull in when you start the dryer. The solution is to slightly bend the bracket that the flap hits when the dryer is at rest. This will cause it to be closer to the hole but not enough to trigger the heat circuit until proper airflow is achieved.
