Dryer takes too long to dry
30 minutes · Easy · Estimated materials $0–$25
Airflow problems are common, expensive and a fire risk. Start at the lint path and exterior vent.
Likely cause
A clogged lint screen, crushed transition duct or blocked exterior flap is restricting airflow.
First safe check
Clean the lint screen and run a timed cycle while checking whether the exterior vent opens strongly.

When to call a professional
Any job
Nothing here says you can't do it. These are simply the moments where a professional is the cheaper answer.
- The same problem comes back after a correct repair.
- The next step needs a tool or permit you don't have.
- You'd be working alone on something that could pin or fall.
- You've lost confidence — that feeling is information, not failure.
