If your dryer gets warm but clothes come out damp — or you're running two and three cycles to dry one load — the problem is almost never the heat. It's airflow. A dryer dries by pushing hot air THROUGH the clothes and out the vent; when that airflow is choked, the moisture has nowhere to go. This is worth fixing fast, and not just for your laundry: a clogged dryer vent is the #1 cause of dryer fires.
Lint builds up in the vent hose and the duct running outside until hot, moist air can't escape — so clothes stay damp and dry times double or triple. It's also the leading cause of dryer fires (the USFA/CSIA recommend service yearly).
Check it: Disconnect and clean the flexible vent hose behind the dryer, and check that the flap on the outside wall opens when the dryer runs. If the run is long or you can't reach it, we clean the full line — we're CSIA C-DET certified.
The lint screen catches lint, but fabric softener and dryer sheets leave an invisible film that blocks airflow through the mesh even when it looks empty.
Check it: Pull the screen, and once a month scrub it under water with a little dish soap and a soft brush — if water pools on the mesh instead of flowing through, it was clogged.
A packed drum leaves no room for air to tumble through the clothes, so nothing dries evenly. Big comforters are the classic offender.
Check it: Dry smaller loads — the drum should be no more than about three-quarters full.
A heating element that's partially failed, or a cycling thermostat that's dropping heat early, produces some warmth but not enough to dry in a normal cycle.
Check it: If the vent and lint screen are clear and it still runs long, the heat side needs a tech to test the element and thermostats.
Auto-dry cycles use a moisture sensor to decide when clothes are dry. A dirty or failed sensor can end the cycle early, leaving clothes damp.
Check it: Try a Timed Dry cycle instead of Auto — if that dries fine, the moisture sensor is the culprit (dryer-sheet residue on the sensor bars can also cause it; wipe them).
Almost always repair — and often the fix is a vent cleaning, not a part at all. Elements and thermostats are affordable when needed. A dryer that takes forever is wasting energy and building fire risk, so it's worth handling promptly.

That's the signature of restricted airflow — almost always a clogged vent or a lint screen with softener film. Clean both; if it still runs long, the heating element or a thermostat is weak and needs a tech.
It can be — the most common cause is a clogged vent, which is the leading cause of dryer fires. If the dryer or laundry room gets very hot or you smell scorching, stop and get the vent cleaned.
Often it's a vent cleaning; if a heating element or thermostat is needed it's an affordable part plus flat labor. Your $50 Quick Check credits toward the repair.
