When a residential clothes dryer suddenly starts making loud, aggressive noises like squeaking, scraping, thumping, or roaring out of nowhere, it points to an acute mechanical failure. Common culprits include a worn-out drum support roller binding against its shaft, a failing rear drum bearing, a snapped rubber glide pad allowing metal-on-metal friction, or a foreign object like a coin trapped between the rotating drum and the outer housing. As these components fail under heavy rotational stress, severe acoustic vibrations echo through the cabinet housing. You can troubleshoot noise sources easily by spinning the drum by hand with the power off. You can verify that your corrective action is successful when disassembling the cabinet, removing trapped foreign objects, and replacing worn support rollers or bearings eliminates the loud noises and restores whisper-quiet operation.
