Dryer taking too long to dry
Soon Long dry times most often mean restricted airflow, and a lint-restricted vent is a fire risk as well as an energy cost; treat it as high if the cabinet is hot to the touch or you smell anything burning.
What this symptom might mean
A dryer that heats but needs two cycles to finish a load is usually moving too little air, not too little heat. Warm, moist air has to leave through the lint screen, the duct behind the machine and the wall cap outside. Lint in any of those, a crushed foil hose behind the dryer, or a wall flap frozen or painted shut will hold the moisture in the drum. Manufacturers list poor venting as the leading cause, and Ottawa winters add one more: an outside flap iced over after a snowfall.
Other possibilities are on the dryer side. A heating element that has partly failed (electric) or a gas valve coil that drops out mid-cycle can give lukewarm air. A moisture sensor coated with softener residue can end sensor cycles early or run them long. And sometimes the dryer is fine and the washer is leaving clothes soaked because it is not spinning properly. The checks below separate those cases.
Safe checks you can do first
- Lint screen. Pull the screen and clean it. If water beads on it instead of running through, wash it with warm soapy water and a soft brush to remove softener-sheet film, then dry it before refitting.
- Duct behind the dryer. Pull the dryer forward and look at the transition duct. Foil or plastic hose that is crushed, kinked or sagging traps lint; a short, smooth run of rigid or semi-rigid metal duct is what manufacturers specify. Do not run the dryer with the duct disconnected indoors.
- Outside wall cap. Run the dryer on air fluff and go outside. The flap should lift with a steady stream of warm air. If it barely moves, the duct is restricted somewhere; if it is frozen or clogged with lint, clear it.
- Load size and sorting. Fill the drum one-half to three-quarters. Towels and jeans mixed with light synthetics leave the heavy items damp when the sensor decides the load is done.
- Cycle choice. Air fluff, delicate and some eco options add little or no heat. Use a sensor cycle such as Normal for everyday loads.
- Washer spin. If clothes come out of the washer dripping, the dryer is doing extra work. A washer that is not spinning is a separate call; see washer not spinning.
- Power (electric dryers). A dryer that tumbles but is barely warm may be on one leg of its 240 V supply. Check for a half-tripped double breaker and reset it fully off, then on. Do not open the terminal block.
Nothing above involves gas, wiring, refrigerant or removing panels. Those are technician-only: Opening the cabinet to reach the blower, thermostats or heating element; Any test on the 240 V terminal block or the gas valve; Work on the gas supply or connector.
Repairs a technician may recommend
After inspection, not from the symptom alone.
- Full vent cleaning and duct replacement. When the outside airflow test fails and lint is found in the duct run. Often the whole fix, and worth doing on any age of dryer.
- Heating element or gas valve coil replacement. When air is lukewarm despite good airflow. Gas-side work is done only by our certified technicians.
- Thermal fuse, cycling thermostat or high-limit thermostat replacement. When a fuse has opened after overheating; the technician also finds the restriction that caused it.
- Moisture sensor cleaning or replacement. When sensor cycles end early with damp clothes but timed cycles dry normally.
- Blower wheel cleaning or replacement. When airflow at the outlet is weak even with a clear duct; lint and socks can lodge in the blower housing.
- Drum seal replacement. When air is leaking around the drum instead of being drawn through the load.
When to book
Book when the outside airflow is weak after you have cleared the lint screen and straightened the duct, when the air in the drum is only lukewarm, or when sensor cycles keep stopping with damp clothes. Tell us whether the dryer is electric or gas and roughly how long the vent run is; a long run through a basement or up to a roof cap takes different tools. The diagnostic visit is $89, waived if you proceed with the repair, and the finding says whether the problem is the dryer, the venting or both. Dryer repair covers the full service.
Questions
How often should a dryer vent be cleaned?
Manufacturers suggest cleaning the full duct every one to two years, more often if the run is long or you dry a lot of towels and bedding. The lint screen should be cleaned before every load.
The dryer is hot but the clothes are still damp. Why?
That pattern usually points to airflow, not heat. Moist air that cannot leave the drum keeps the load wet no matter how hot the element is.
Can a long dry time be the washer's fault?
Yes. If loads come out of the washer heavier than usual, the washer's spin may be the problem. Run a spin-only cycle and see whether the clothes are wrung out properly.
Is foil duct really a problem?
Manufacturers say to use rigid or semi-rigid metal duct. Foil and plastic hose sag, trap lint in their ridges and crush easily when the dryer is pushed back against the wall.
