Dryer overheating

The cabinet, clothes, or room becomes unusually hot, or the dryer stops on a temperature warning.

Start hereStop the dryer and let it cool before checking anything.

Narrow it down

What this symptom can tell you

The cabinet and laundry are much hotter than usual

Restricted airflow or a temperature-control problem may be allowing heat to build.

The dryer stops and restarts only after cooling

Over-temperature protection may be interrupting operation because airflow is poor or an internal issue is present.

The room becomes hot or humid

The exhaust may be disconnected, crushed, blocked, or venting indoors.

These patterns narrow the next check; they do not confirm a failed part. Use the exact model number and any displayed code before ordering parts or authorizing repair.

Try these checks in order

Exact controls and access points differ by model. Stop when a step does not match your appliance or manual.

  1. 1

    Clean the lint screen

    Remove lint and reinstall the screen. Do not run the dryer without it.

    What you want: The screen is fully clear.
  2. 2

    Check the load

    Remove an oversized or tightly packed load. Items must tumble for air to circulate.

    What you want: The drum is no more than loosely filled.
  3. 3

    Check the exterior vent

    After cooling, inspect the outside hood for lint, nests, ice, or a stuck flap.

    What you want: The hood opens freely and is not blocked.
  4. 4

    Confirm the cycle

    High Heat is not suitable for every fabric. Choose the recommended setting.

    What you want: The cycle matches the fabric label.
  5. 5

    Arrange vent cleaning

    If airflow is weak, stop using the dryer until the full vent path is professionally inspected and cleaned.

    What you want: The complete vent path is confirmed clear.

Most common categories

Possible causes to consider

  • A clogged lint screen or restricted exhaust duct.
  • A crushed or disconnected transition duct behind the dryer.
  • An overloaded drum that limits air movement.
  • An exterior vent flap that does not open freely.
  • A thermostat, sensor, heater, burner, blower, wiring, or control issue requiring service.

Stop and arrange help when

  • There is a burning smell, smoke, glowing material, or scorched lint.
  • The plug, cord, outlet, or breaker is hot.
  • You smell gas. Leave the area and contact the gas utility or emergency service.
  • The dryer remains unusually hot after airflow is restored.

If the problem remains

Find the full model number. Open the official manual, check for a recall, and describe which checks you completed before contacting service.

Common questions

Dryer overheating: FAQs

How hot is too hot for a dryer?

Dryers normally become warm, but scorching laundry, a cabinet too hot to approach safely, burning odor, smoke, or repeated shutdowns are stop-use conditions.

Can a blocked dryer vent cause a fire?

Lint and restricted airflow can contribute to excessive heat and fire risk. Stop using the dryer until the exhaust path is corrected.

Can I test the dryer with the vent disconnected?

Do not vent a dryer indoors or operate it in a configuration not approved by the manufacturer. Have the exhaust system inspected safely.
