When performing maintenance on your bottom hinged trash or laundry chute, one of the main things you want to check is the chute closure. You want to make sure that this particular gas closure is free of dents or cracks that could impede proper movement. Often called a gas piston or gas spring, it looks exactly like a piston and should be easy to locate. You should note the following during the inspection: The gas piston, the piston chamber tube, and the ball joints on both ends. The mechanism when opened fully is about 17” and around 10” when closed and the gas piston should open and close completely as the extended function opens and closes your chute door. Aside from a physical inspection, you should also listen to the chute closure while attempting to close the chute door. What you are listening for is any excessive leaking air or sticking points in the closure which could mean the part is broken and needs replaced.
