A dryer that used to finish a load in 45 minutes and now needs two full cycles isn't just annoying — it's usually a clear sign something specific has gone wrong. The good news is that most causes are easy to identify once you know what to check.
The most common causes, starting with the easiest fix
A clogged lint screen or exhaust vent
This is the single most common cause, and the easiest to check yourself. A lint screen packed with residue, or a vent line clogged further down, blocks airflow and traps moisture inside the drum. See our guide on dryer vent cleaning for how often to clear it.
A failing heating element or igniter
If the drum is turning and tumbling normally but the air inside feels barely warm, the heating element (electric dryers) or igniter (gas dryers) is likely wearing out. This is a repair, not a cleaning fix.
A faulty thermostat or thermal fuse
These parts regulate and protect against overheating. When one starts failing, the dryer may run cooler than it should as a safety response, extending dry time even though everything else seems fine.
Overloading the drum
Cramming in a large or bulky load restricts airflow around the clothes themselves, even if the machine is working perfectly. Smaller, better-separated loads often dry noticeably faster.
A worn drum seal or belt
If the drum isn't tumbling smoothly, clothes bunch together and dry unevenly. A worn belt or seal is a mechanical fix, and it's often accompanied by a squeaking or thumping noise.
Touch the outside of the dryer cabinet mid-cycle. If it feels unusually hot, airflow is likely blocked somewhere (vent or lint screen). If the drum feels barely warm at all, it's more likely a heating element or igniter issue.
Why this is worth fixing, not just working around
Running extra cycles to compensate for slow drying does more than waste time and electricity — it puts additional wear on the belt, motor, and heating components, since they're running far more than they were designed for. A quick fix now is almost always cheaper than the repair that follows a few more months of overuse.
When it's a bigger safety concern
If slow drying is paired with a burning smell, visible lint around the machine, or a vent that feels hot to the touch on the outside wall, stop using the dryer and have the vent system checked. A blocked vent isn't just an efficiency problem — it's a well-documented fire risk.
Still taking two cycles to dry a single load?
