What to do if…
your clothes dryer smells unusually hot or burnt and you suspect a venting problem

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Stop the cycle, switch the dryer off, and unplug it if you can do that without going near heat, smoke, sparks, or flames. If there is smoke, fire, crackling, sparks, or the smell is getting worse, leave, close the room door if safe, and call 999.

Do not do these things

  • Don’t run the dryer again to see if the smell goes away.
  • Don’t ignore a burning or unusual smell, smoke, sparks, scorch marks, or a dryer that feels unusually hot.
  • Don’t pull the dryer out, touch the plug, or handle the vent hose while anything is hot, smoking, sparking, or unsafe.
  • Don’t keep using the dryer just because you cleaned the lint filter; the blockage or fault may be elsewhere.
  • Don’t dismantle the dryer or remove panels yourself.
  • Don’t try to put out an appliance fire yourself; get out, stay out, and call 999.

What to do now

  1. Stop the dryer. Turn it off at the control panel.
  2. Switch off at the socket and unplug it only if you can do so without reaching past heat, smoke, sparks, or flames.
  3. If there is smoke, fire, sparks, crackling, or a worsening burnt smell, leave the room, close the door if safe, get everyone out, and call 999.
  4. If there are no danger signs and the dryer is fully cool, clean the lint filter and remove loose lint from around the filter housing and door area if you can reach it safely.
  5. If it is a vented dryer and access is safe, look for an obvious crushed, kinked, disconnected, or blocked vent hose behind the dryer. Do not force the dryer out from a tight space.
  6. If the outside vent is safely reachable, look for obvious lint build-up, debris, or a stuck vent flap. Skip this if it involves ladders, leaning out, moving heavy furniture, or unsafe access.
  7. Do not use the dryer again until the airflow problem and the dryer have been checked. A blocked or crushed vent, lint build-up, or an appliance fault can increase fire risk.
  8. If you rent, report it urgently to your landlord or letting agent in writing. Say the dryer has an unusually hot or burnt smell, you have stopped using it, and you suspect a venting or appliance safety problem.
  9. If you own the appliance, arrange a qualified appliance professional to check the dryer, and arrange competent help to inspect or clear the vent run if it is long, hidden, blocked, crushed, or hard to reach.
  10. Find the model and serial number, usually near the door or on the rating plate, and check the manufacturer’s safety notice page and the GOV.UK product safety alerts, reports and recalls service. If the appliance is affected, do not use it until the manufacturer’s remedy is complete.

What can wait

  • You do not need to decide now whether to replace the dryer.
  • You do not need to dismantle the dryer, open panels, or push cleaning tools into hidden ducting.
  • You do not need to solve the whole ventilation route tonight if the dryer is switched off, not being used, and there are no emergency signs.
  • Routine prevention, such as improving duct routing or setting a cleaning schedule, can wait until the immediate safety concern has been checked.

Important reassurance

A burnt or unusually hot smell from a dryer is a reasonable reason to stop using it. Pausing, keeping clear of anything hot or smoking, and getting it checked is a sensible first step, not an overreaction.

Scope note

These are first steps to reduce immediate fire risk and buy time. Repairs, fault-finding, concealed vent checks, and decisions about continued use may need help from a qualified appliance professional, a competent vent-cleaning service, the manufacturer, your landlord, or your local fire safety service.

Important note

This is general information, not professional fire-safety, electrical, legal, or property advice. If you think there is immediate danger, prioritise getting out and calling 999.
