Direct answer: If your dryer takes multiple cycles to dry, the most common cause is restricted airflow through the lint path or vent, not a bad part inside the dryer.
Most likely: Packed lint in the lint screen housing, a crushed or long vent run, or an outside hood that is stuck partly shut can leave clothes warm but still damp after one cycle.
Start with the easy airflow checks and watch what the dryer is actually doing: are clothes hot but damp, barely warm, or cool at the end? That one detail separates a vent problem from a heating problem fast. Reality check: most "bad dryer" calls on this symptom end up being vent restriction. Common wrong move: running cycle after cycle without fixing airflow, which bakes lint harder into the vent and overheats the dryer.
Don’t start with: Do not start by ordering a dryer heating element or gas ignition parts just because the drum turns. A dryer can still make some heat and dry poorly when the real problem is air not moving.
The dryer finishes a full cycle, towels feel hot or steamy, but heavier items are still wet in the middle.
Start here: Start with airflow restriction. Warm, damp loads usually mean heat is present but moisture is not leaving the drum fast enough.
Loads that used to dry in 40 to 60 minutes now need 90 minutes or more, especially jeans and towels.
Start here: Check the full vent path, outside hood, and lint screen housing before suspecting internal parts.
A few shirts dry fine, but bedding or towels need two or three cycles.
Start here: Look for marginal airflow or a partially weak heat source. Bigger loads expose a vent problem quickly.
The drum tumbles normally, but clothes stay cool or only slightly warm even on a high-heat cycle.
Start here: After basic airflow checks, move to the heating circuit branch. This points more toward a failed dryer heating component than a vent alone.
This is the top cause when the dryer still heats some but needs extra time. Moist air stays trapped in the drum, so clothes feel warm yet stay damp.
Quick check: Run the dryer on a heat cycle and check outside. The exhaust should push a strong, steady stream of warm air and fully open the hood flap.
Fabric softener and detergent residue can coat the dryer lint screen so air slips around it instead of through it.
Quick check: Hold the clean screen under running water. If water pools on top instead of flowing through, the screen needs washing with warm water and mild soap.
An electric dryer with a partially failed heating circuit or a gas dryer with ignition trouble may still warm clothes a little, but not enough to finish a normal load.
Quick check: Mid-cycle, open the door carefully. The drum air should feel clearly hot on a high-heat setting, not just lukewarm.
If airflow is decent but heat cuts out too early or does not return properly, drying times stretch out even though the dryer seems to run normally.
Quick check: After ruling out vent restriction, note whether heat starts strong and then fades, or never gets fully hot at all.
Most long dry times come from air restriction outside the drum, and these checks cost nothing.
Next move: If airflow improves and the next load dries normally, the problem was vent or lint-path restriction. If airflow outside is still weak or the vent run is clearly packed with lint, treat the vent as the main problem before suspecting internal dryer parts.
What to conclude: A dryer that heats but cannot move moist air will act underpowered even when the heater is fine.
You need to know whether the dryer is making enough heat and whether that heat changes when the vent is removed.
Next move: If the dryer blows strongly and heats much better with the vent disconnected, the dryer itself is usually fine and the house vent path is restricted. If airflow at the dryer outlet is decent but heat is still weak or missing, move to the internal heating branch.
What to conclude: This quick split test keeps you from replacing dryer parts when the real choke point is the vent run in the wall or outside hood.
A dryer with marginal airflow or heat often shows up first on bulky loads and low-heat settings.
Next move: If a normal test load dries in one cycle after correcting settings or load size, the dryer may be okay and the issue was operating conditions. If even a medium load on timed high heat still needs extra time, keep going. That points back to airflow or a heating component problem.
Once the vent path is ruled out, long dry times usually come from a heater that is weak, intermittent, or not cycling correctly.
Next move: If you identify a clear weak-heat pattern, you can narrow parts to the heating circuit instead of guessing. If the heat behavior is inconsistent, the dryer overheats, or diagnosis is still muddy, stop before replacing multiple parts blindly.
By now you should know whether the dryer is being choked by airflow or failing to make proper heat.
A good result: If the load dries in one normal cycle and outside airflow stays strong, the repair path was correct.
If not: If drying is still slow after a confirmed vent cleaning or heating-part repair, the dryer needs deeper diagnosis for wiring, sensor, or control issues.
What to conclude: You have either fixed the main restriction or reached the point where further part swapping is more likely to waste money than solve the problem.

Because heat alone is not enough. The dryer has to move moist air out of the drum. If the vent or lint path is restricted, clothes get warm and steamy but the moisture stays trapped, so drying time stretches out.
Yes. That is the most common real-world cause. A partially blocked vent often shows up first as longer dry times, especially with towels, jeans, and bedding.
That usually means the dryer is right on the edge. Marginal airflow or weak heat can handle a small load but not the moisture from a full load. Check the vent first, then the heating pattern.
Not until you have ruled out airflow. A restricted vent can make a perfectly good heater look weak. If airflow is strong and the dryer still never gets properly hot, then the heating element becomes a reasonable suspect on an electric dryer.
Not for long. Extra cycles can overheat lint buildup, stress heating parts, and raise fire risk. If drying time suddenly jumps, fix the airflow or heat problem before making it your new normal.
