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

Short answer

Stop the cycle, switch the dryer off and unplug it (if safe). If there’s smoke, flames, or the smell is rapidly worsening, get everyone out and call 999 (or 112).

Do not do these things

  • Don’t “run it a bit longer” to see if the smell goes away.
  • Don’t try to investigate if there’s smoke/heat—prioritise getting out and calling 999/112.
  • Don’t open the door if you suspect smoke/heat inside; leave it closed while you power down and evacuate if needed.
  • Don’t keep using the dryer after only emptying the lint filter if the smell was unusually hot/burnt (the restriction may be deeper).
  • Don’t pull the dryer out or disconnect ducting if anything is hot, smoking, or you feel unsafe.
  • Don’t use water on a suspected electrical appliance fire or attempt to fight a fire unless you’re trained and it’s clearly safe.

What to do now

  1. Stop and power down. Turn the dryer off. Switch off at the socket and unplug if you can do so without reaching through heat or smoke.
  2. Decide if this is an emergency right now. If you see smoke, hear crackling, see flames, or the smell is rapidly intensifying: leave the room, close the door, evacuate, call 999/112.
  3. Let it cool completely. Give it time to cool before touching the back, the plug, or any venting.
  4. Do a quick, no-restart check once fully cool (do not run the dryer).
    • Clean the lint filter thoroughly (and remove any lint around the filter housing you can safely reach).
    • If your dryer vents outside, look behind for an obviously crushed/kinked vent hose (don’t force it straight if access is awkward).
    • If you can safely access the outside vent, visually check for obvious blockage (lint build-up, a stuck flap, debris). If it’s not safely reachable, skip this step.
  5. Do not use the dryer again until it’s checked/cleared. Vent restrictions can cause overheating and increase fire risk.
  6. Arrange the right help (and document it).
    • If you rent: report it as urgent to your landlord/letting agent in writing. Say you’ve stopped using the dryer due to an overheating/burnt smell and suspected vent restriction.
    • If you own: arrange a qualified appliance repair engineer and, if applicable, professional help to inspect/clear the vent run (especially if it’s long, concealed, or hard to access).
  7. Check for safety notices/recalls. Find the model and serial number (often inside/around the door area) and check the manufacturer and UK product safety recall/alert listings. If affected, do not use until remedied as directed.

What can wait

  • You don’t need to dismantle the dryer, open panels, or run cleaning tools through hidden ducting right now.
  • You don’t need to decide today whether to replace the appliance—first confirm whether venting and the dryer are safe.
  • You can handle longer-term prevention (routine vent cleaning, improving duct routing/materials) after the immediate risk is under control.

Important reassurance

A sudden “hot/burnt” smell is a valid reason to stop immediately. Many people second-guess themselves—pausing use and getting it checked is a sensible safety-first step.

Scope note

This is first-steps guidance to reduce immediate fire risk and buy time. Fault-finding and repairs should be done by a qualified professional, especially where venting runs through walls/ceilings or the appliance may be faulty.

Important note

This is general information, not professional fire-safety or electrical advice. If you think there is any immediate danger (smoke, flames, or you feel unsafe), prioritise evacuation and call 999/112.
