Why Your Kenmore Dryer Takes Too Long
A dryer that requires two or three cycles to dry a normal load is expensive to operate and a sign that something is wrong. Most cases can be resolved with maintenance, but some require component replacement. This guide covers the entire diagnostic process.
Cause 1: Clogged Dryer Vent (Most Common)
A blocked exhaust vent is the leading cause of long dry times. Lint accumulates in the vent duct over months and years, restricting airflow. The dryer cannot remove moisture efficiently without adequate exhaust airflow. Signs of a blocked vent: the dryer runs hot, laundry room becomes humid during operation, and clothes feel hot but damp after a full cycle.
Clean the vent duct from the dryer to the exterior cap using a dryer vent cleaning brush kit. Also check the exterior vent cap — birds sometimes build nests in dryer vents, completely blocking them.
Cause 2: Lint Screen Not Cleaned
The lint screen should be cleaned before every single load. A loaded screen significantly reduces airflow. Even after cleaning, residue from dryer sheets can clog the mesh — periodically wash the lint screen with warm soapy water, rinse, and let it dry completely before reinstalling.
Cause 3: Overloading
Overloading a dryer dramatically increases drying time — there is not enough space for hot air to circulate around the laundry. A correctly loaded dryer drum should be about 3/4 full, allowing clothes to tumble freely.
Cause 4: Failed Heating Element
If the dryer tumbles but produces no heat, the heating element has failed. Test: run the dryer for 5 minutes on high heat and carefully feel the laundry — if it is still cold and wet, there is no heat.
Cause 5: Gas Supply (Gas Dryers)
For gas Kenmore dryers, verify the gas supply valve is fully open and the igniter is functioning. A failing igniter causes intermittent or no heating, significantly extending dry times.
