Observation-led dryer troubleshooting
Dryer not drying clothes?
Use two observations first: does the dryer make heat, and is strong air leaving the outside vent? Those clues separate most airflow, loading, cycle, and power problems without opening the appliance.
Direct answer
Match the behavior before checking parts
- Hot + still damp
- Prioritize the lint screen, load size, connector, exterior hood, and concealed vent.
- Turns + no heat
- Check cycle settings and, for an electric dryer, both linked breaker handles once.
- Very hot or stops
- End the test. Restricted airflow or temperature control may be unsafe.
- Will not start
- This guide is not the right path; preserve any displayed code and diagnose the start condition.
Decision table
What the dryer’s behavior suggests
A symptom is not a parts diagnosis. Use the safest observation that distinguishes the next branch.
| What you observe | What it suggests | Safest next move |
|---|---|---|
| Dryer is hot, clothes are damp, outside airflow is weak | Moist air is probably trapped by a restricted exhaust path | Stop and serviceClean accessible points, then arrange complete vent cleaning before more drying. |
| Airflow is strong, but a large mixed load remains damp | Overloading, tangled items, or a sensor cycle ending early may be involved | Owner checkSeparate heavy from light items and test a smaller load on the correct cycle. |
| Electric dryer tumbles normally but produces no heat | One side of the paired supply may be interrupted, or the heating circuit may need service | Owner checkCheck both linked breaker handles once; use qualified help if heat does not return. |
| Gas odor, repeated ignition attempts, or no heat on a gas dryer | A gas supply or ignition problem may be present | Stop and serviceDo not keep testing, operate valves, or seek a spark. Leave the area and follow local gas-safety guidance. |
| Dryer or laundry becomes unusually hot | Airflow or temperature regulation may be unsafe | Stop and serviceEnd the cycle, disconnect power if safe, and arrange inspection. |
Safe diagnostic path
Check these five things in order
- 01
Clean the lint screen. Remove lint and any residue coating the mesh. A clean-looking screen can still be blocked by film.
- 02
Correct the load and cycle. Separate dense towels from light clothing, untangle large items, avoid overfilling, and choose a cycle intended for the fabric.
- 03
Inspect the visible connector. Stop the dryer first. Look for crushing, a sharp kink, excess length, or damage behind it without moving a gas connection.
- 04
Check the exterior exhaust. From a safe ground-level location, confirm strong airflow after five to ten minutes. Weak flow calls for a complete vent inspection.
- 05
Check electric-dryer power once. If the drum turns with no heat, confirm both linked breaker handles are fully on. Never open a panel or measure live voltage.
Know when to stop
Do not continue a test cycle when safety changes
Turn the dryer off and seek qualified help when any of these conditions appears.
- Smoke, burning odor, scorching, or a gas smell
- An unusually hot cabinet, plug, cord, receptacle, or load
- A breaker that trips again after one reset
- A damaged, detached, or inaccessible exhaust connection
- Weak exterior airflow after the accessible points are clean
Primary source
Why airflow comes first
Whirlpool’s current AF and Check Vent guidance identifies a clogged lint screen or vent, a crushed or kinked connector, a blocked exterior hood, and excessive vent turns as causes of restricted airflow. Faultwise uses that official inspection order and adds conservative safety boundaries.

Dryer not drying FAQ
Why is my dryer running but not drying clothes?
If the drum turns but clothes stay damp, first separate an airflow problem from a heat problem. A hot dryer with weak exhaust points toward a restricted vent or loading issue; a normally turning electric dryer with no heat can still have one side of its paired supply interrupted.
Can a clogged dryer vent make clothes stay wet?
Yes. A restricted exhaust cannot remove humid air efficiently, so loads can remain damp while the cabinet and laundry become unusually hot. Stop and arrange complete vent cleaning if exterior airflow is weak after the accessible checks.
Why does an electric dryer spin but not heat?
The motor can sometimes run while the heater does not receive the full supply. Check the correctly identified paired breaker handles once, without opening the dryer or measuring live voltage. Repeated trips, heat, damage, or a continuing no-heat condition require qualified help.
When should I stop using a dryer that is not drying?
Stop immediately for smoke, a burning or gas odor, scorching, abnormal heat, repeated breaker trips, a damaged vent, or a hot or discolored plug, cord, or receptacle.
