Whirlpool Dryer: long drying time
What is this symptom?
Experiencing long drying times with your Whirlpool dryer? This common issue often leads to clothes remaining damp even after a full cycle. Typical causes include airflow restrictions or insufficient heat production. Understanding these factors can help you troubleshoot effectively.
Important Tips for Whirlpool Models
- Whirlpool dryers may display AF or Check Vent error codes indicating restricted airflow; EcoBoost option on some models increases drying time by design.
Possible Causes
Restricted airflow due to clogged venting or lint build-up
How to Identify: Dryer vent exits to outside are blocked; AF/Check Vent error codes on some Whirlpool models; little airflow from lint trap; steam or moisture inside dryer at end of cycle. (Product Help | Whirlpool
Part: Dryer vent system, lint filter
Insufficient heat production (faulty heating element or thermostat)
How to Identify: Dryer feels warm but not hot enough; clothes remain damp; multimeter shows open circuit on heating element or thermostat. (授æƒå®¶ç”µ
Part: Heating element, cycling thermostat
Faulty moisture sensor
How to Identify: Dryer runs longer than necessary and may misreport dryness; cleaning sensor may improve. (授æƒå®¶ç”µ
Part: Moisture sensor bars
Overloading drum or improper load sizes
How to Identify: Drying times reduce when smaller loads are used. (授æƒå®¶ç”µ
Part: Drum load practice
Blower wheel obstruction or damage
How to Identify: Poor airflow even with clean vents; possible noise; drum failing to tumble freely.
Part: Blower wheel
DIY Solutions
Clean lint filter and airflow paths
- Remove lint filter and clear all lint by hand.
- Rinse the filter with warm soapy water if residue from softener is present; dry and reinstall.
- Check near lint trap housing for trapped lint and clear with soft brush.
Inspect and clean dryer vent and ducting
- Unplug the dryer and pull it away from the wall.
- Disconnect the vent hose from the dryer and exterior vent.
- Use a vacuum and/or vent brush kit to remove lint and debris from both ends of the vent and hose.
- Reattach vent, ensure no kinks or crushes in duct, and push dryer back into place.
Reduce load size and separate heavy fabrics
- Remove excess items from the dryer so it’s no more than ~¾ full.
- Separate heavy fabrics (jeans, towels) into smaller loads.
- Restart drying cycle with adjusted load.
