visibilityHow to check airflow at the vent
- Start a normal (or air-fluff) cycle so the dryer is pushing air, then go outside and find the vent hood on the wall — the flap should swing open and blow a strong stream of warm air.
- Hold your hand a few centimetres from the flap. Strong, warm airflow means the run is clear; a flap that barely lifts, or weak or cool air, means lint is choking the duct or the hood.
- Check the hood itself for a matted plug of lint, and look for lint fuzz built up on the wall around it — a common sign the whole run needs cleaning.

With the dryer unplugged (and gas shut off on a gas model), disconnect the duct, clear the transition hose, the rigid wall duct, and the outside hood with a dryer-vent brush and a vacuum, then reconnect and confirm strong airflow at the hood.
- Unplug the dryer (or switch off its breaker; on a gas dryer, close the gas shutoff valve). Pull the dryer far enough out to reach the duct connection.
- Loosen the clamp and slide the transition hose off both the dryer and the wall. Vacuum out the packed lint you'll find at each end.
- Feed a dryer-vent brush through the rigid wall duct from inside and again from the outside hood, working the lint loose, then vacuum it out.
- Clear the outside vent hood so the flap swings freely, reconnect the hose with the clamps snug, restore power/gas, and run a cycle to confirm strong warm airflow at the hood.
Cleaning the lint filter, transition hose, exhaust duct, and outside vent hood is routine homeowner maintenance in every province. Internal repairs — replacing an electric heating element or thermostat, or a gas dryer's igniter/burner — route to a licensed appliance technician, and gas-dryer work adds a gas-fitting concern.
