If your dryer smells like burning, act quickly but stay calm — that odor usually points to a mechanical issue rather than a house fire. The most common cause is excessive lint build-up in the lint trap or venting; clogged ducts or a full lint filter will overheat the element or burner and create a burning smell. Next most likely is a stretched, frayed, or slipping drive belt that rubs on pulleys and smells like it is burning; check that the drum and idler pulley turn freely. A shorted main control board can also emit a hot, electrical odor, so inspect the board for burn marks or damaged components. Less often the blower belt or blower wheel is stuck or slipping, and a seized idler pulley or idler assembly will let the belt slip and overheat. You can fix many of these issues yourself with basic parts and tools, and you can enter your model number on RepairClinic.com to find the exact replacement part for your specific dryer.
