Hearing a loud, rhythmic thumping, chopping, or whirring noise from inside a residential clothes dryer during operation that resembles a helicopter is typically caused by a flat spot on one of the rubber support rollers, a loose drum baffle striking the inner basket, or a torn drive belt with a damaged section slapping against the lower cabinet housing. As the drum rotates, the deformed roller wheel or flapping belt creates a cyclical, rhythmic impact noise that echoes loudly. You can troubleshoot mechanical noises easily by turning the drum slowly by hand. You can verify that your corrective action is successful when inspecting the interior drum baffles, replacing flat-spotted support rollers, or installing a new drive belt stops the helicopter-like thumping noise entirely and restores smooth rotation.
