Product review (5 stars): If this is what you need, it's perfect
I have to love this because it fixed the dryer. ;)
This "lever" is really better described as an actuator for the door switch. If it breaks during a cycle the dryer will shut off and then won't turn on again since it "thinks" the door is open.
The actuator is not terribly difficult to replace (just watch for sharp metal edges as you would working in any appliance and be sure to unplug the dryer!) and the price on Amazon is terrific.
