A slow-drying dryer is more than just an inconvenience can increase energy costs, wear out fabrics faster, and reduce the lifespan of your appliance. According to the U.S. Department of Energy, dryers account for 5% of total household energy use, and a faulty dryer can consume up to 75% more energy than necessary. In this guide, we’ll troubleshoot the most common causes of a Kenmore dryer taking too long to dry, provide step-by-step fixes, and share safety tips to keep your appliance running efficiently.

Common Causes of a Kenmore Dryer Taking Too Long to Dry
Several factors can lead to longer drying times. Below are the most common reasons:
1. Clogged Lint Filter or Dryer Vent: A blocked lint filter or dryer vent restricts airflow, preventing moisture from escaping. This leads to damp clothes even after a full drying cycle.
Fact: A clogged lint filter can reduce airflow by up to 50%, significantly increasing drying time.
2. Overloaded Dryer: Overloading the dryer reduces airflow within the drum, preventing clothes from drying evenly. The dryer struggles to circulate warm air properly, leading to longer drying cycles.
3. Faulty Heating Element: A Kenmore electric dryer relies on a heating element to generate hot air. If the heating element is damaged or partially burned out, the dryer will produce less heat, causing longer drying times.
4. Malfunctioning Thermostat: The cycling thermostat regulates the dryer’s temperature. A faulty thermostat may prevent the dryer from reaching the correct temperature, leading to extended drying times.
5. Worn-Out Blower Wheel: The blower wheel moves hot air through the drum and out the vent. If the blower wheel is loose, clogged, or damaged, airflow decreases, making drying inefficient.
6. Incorrect Dryer Settings: Modern Kenmore dryers offer multiple settings. If you accidentally use a low-heat or air-dry setting, drying times will naturally be longer.
Now that we’ve identified the potential causes, let’s go over how to fix each issue step by step.
How to Fix a Kenmore Dryer That’s Taking Too Long to Dry
1. Clean the Lint Filter & Dryer Vent
Warning: Lint buildup is a leading cause of dryer fires. The U.S. Fire Administration reports that dryers cause 2,900 fires annually, resulting in $35 million in property damage.
How to Clean the Lint Filter:
- Remove the lint screen and wash it with warm, soapy water to remove residue buildup.
- Let it dry completely before reinserting it.
How to Clean the Dryer Vent:
- Unplug the dryer and disconnect the vent hose from the back.
- Use a vacuum cleaner or vent cleaning brush to remove built-up lint.
- Check the exterior vent (outside your home) to ensure it’s not blocked.
- Reattach the vent hose securely and run a test cycle.
Recommended Frequency: Clean the lint filter after every load. Clean the dryer vent every 6-12 months.
2. Avoid Overloading the Dryer
Overloading prevents proper air circulation , causing clothes to dry unevenly.
How to Load Your Dryer Correctly:
- Small loads: No more than 1/3 full
- Medium loads: Fill about 1/2 of the drum
- Large loads: No more than 2/3 full
Pro Tip: Use wool dryer balls to improve airflow and reduce drying time by up to 25% .
3. Check & Replace the Heating Element
A faulty heating element results in low heat output , causing longer drying cycles.
How to Test the Heating Element:
- Unplug the dryer for safety.
- Remove the back panel to locate the heating element (usually near the bottom).
- Use a multimeter to test for continuity. If there’s no continuity, the element is faulty and needs replacement.
Replacement Tip: Always buy a Kenmore-compatible heating element to ensure proper performance.
4. Test & Replace the Cycling Thermostat
A defective thermostat prevents the dryer from reaching the correct temperature, extending drying time.
How to Test the Thermostat:
- Unplug the dryer and locate the thermostat (usually near the blower housing).
- Remove the wires and test for continuity with a multimeter.
- If there’s no continuity, replace the thermostat with a new one.
5. Inspect & Fix the Blower Wheel
A loose or obstructed blower wheel reduces airflow, making drying inefficient.
How to Check the Blower Wheel:
- Unplug the dryer and remove the front or back panel.
- Manually spin the blower wheel-it should rotate smoothly.
- If it's loose or clogged, remove lint buildup or replace the wheel if necessary.
When to Replace: If the wheel is cracked or makes rattling noises.
6. Adjust Dryer Settings for Optimal Drying
If you accidentally set the dryer to low heat, air fluff, or delicate, drying time will increase.
Best Dryer Settings for Faster Drying:
- High Heat - Best for towels, jeans, and heavy fabrics.
- Medium Heat - Ideal for synthetics and casual wear.
- Low Heat or Delicate - For lingerie, activewear, and delicate fabrics.
Pro Tip: Use the "Sensor Dry" function (if available) to automatically adjust drying time based on moisture levels.
Safety Tips for Using Your Kenmore Dryer
- Clean the lint trap before every load to prevent fire hazards.
- Never leave the dryer running overnight or when leaving home.
- Use only metal dryer vents - plastic or foil vents can overheat and catch fire.
- Keep the area around the dryer clear of flammable materials.
- Check for burning smells-this could indicate overheating or a failing component.
When to Call a Professional
If you’ve tried these fixes and your Kenmore dryer is still taking too long to dry, it may have a more serious issue, such as:
- A faulty control board (which regulates heating and timing).
- A damaged moisture sensor (which detects when clothes are dry).
- Electrical issues affecting heating elements or thermostats.
If your dryer is still under warranty, contact Kenmore customer support or hire a certified technician for repairs.
Final Thoughts
If your Kenmore electric dryer is taking too long to dry, don’t ignore it - this issue wastes time, energy, and money. By following these troubleshooting steps, you can restore efficiency, prevent costly repairs, and extend the life of your dryer.
