Ventless dryer not drying: cleaning the filters, condenser and heat exchanger

Ventless dryers depend on clean air passages. Lint that gets past the door filter settles on the condenser or heat exchanger and drying time climbs. Clean every filter stage first, then the condenser or exchanger, then check the water path.

Dryer squeaks, squeals or thumps: drum rollers, idler pulley, glides and rear bearing

Drum noise usually comes from four wear parts: the drum support rollers (thump, squeak), the idler pulley (squeal or whine), the front glides or bearing slides (scraping) and, on some designs, a rear drum bearing (squeal, drum moves front to back). Take the belt off and turn the drum by hand to find which one it is. Replace rollers as a set.

Replacing a broken or slipping dryer drum belt

A broken belt leaves the motor spinning with no drum movement. Open the cabinet, put the new belt around the drum with the ribbed side against the drum, then route it through the idler and onto the motor pulley. Inspect the idler and rollers while you are in there.

How to test a dryer thermal fuse

A thermal fuse is a one-time safety link that opens permanently when the exhaust gets too hot. It is a simple continuity test, but a blown fuse is a symptom: the real cause is almost always a restricted vent or a failed cycling thermostat.
