A high-pitched squealing, screeching, or whistling noise coming from a residential clothes dryer during operation is typically caused by severe friction in worn-out drum support rollers, a dry or misaligned idler pulley, a slipping rubber drive belt, or worn felt drum glides. As these mechanical components degrade under heavy rotational loads, metal-on-metal or plastic-on-metal friction generates high-frequency acoustic vibrations. You can troubleshoot noise sources easily by spinning the drum by hand with the power disconnected. You can verify that your corrective action is successful when disassembling the cabinet, lubricating roller shafts with high-temperature grease, or replacing worn support rollers and pulleys eliminates the high-pitched noise entirely.
