A GE GTD84 that thumps, squeals or rumbles is giving you a diagnosis in the sound, because the noises of a dryer map neatly on to its wear parts. The GTD84 is a 7.4 cubic foot top-control electric dryer with an aluminised alloy drum. The drum rests on rollers or glides at the back and the front and is turned by a belt that runs round the drum, an idler pulley and the motor pulley. Almost every noise comes from one of these parts wearing out, and a few come from objects that have fallen into the cabinet.
The checks in more detail
Listen to the pattern. A thump that repeats once per turn of the drum, getting faster as the drum speeds up, is the signature of a flat spot on a drum roller or a worn glide, and it is often louder when the drum is full. A squeal or a chirp that begins as soon as the drum starts and continues is typically the idler pulley bearing or a dry roller; a high-pitched squeal that comes and goes may be the belt slipping.
A scraping sound, especially with a smell of hot rubber, can be the drum rubbing against a worn felt or seal at the front. A deep rumble that rises when the motor starts points to a failing motor bearing, and a rattle that comes and goes can be a coin in the lint trap housing or between the drum and the cabinet. Do the safe checks. Unplug the dryer, pull out the lint screen and look down the lint housing for a coin or a button;
clean the lint screen and the vent, since a restricted vent adds heat and strain. Turn the drum by hand: it should rotate smoothly with a little resistance and no roughness or catching. If it thumps as you turn it, the roller or glide is the cause. Replacement of rollers, an idler or a belt is a routine repair, but it needs the cabinet opened, so book a technician or follow the model's repair guide with the part numbers for GTD84ECPNDG.
