Yes, a persistently squeaky residential clothes dryer can indirectly create a serious fire hazard over time if the squeaking is caused by severe friction in worn-out drum support rollers, dry bearing shafts, or a binding idler pulley. When metal and plastic components grind together under heavy loads, they generate extreme localized heat that can ignite flammable lint dust accumulating nearby in the lower cabinet housing. You can troubleshoot friction noises easily by listening to the drum rotation. You can verify that your corrective action is successful when shutting down the appliance, disassembling the cabinet, and lubricating or replacing worn rollers, bearings, and pulleys eliminates the squeaking friction entirely and prevents dangerous overheating.
