Tumble dryer smells of burning (all brands)
⚠️ This needs a qualified professional
This fault involves gas or mains electrical work. Don't attempt a DIY repair — UK law requires gas work to be carried out by a Gas Safe registered engineer. Below is what to check and describe to them, not step-by-step repair instructions.
A burning smell from a tumble dryer is a genuine safety matter, given that tumble dryer fires are a recognised UK product safety issue with documented past recalls — this is one to take seriously rather than something to keep testing yourself.
What’s safe to check first
- Stop the dryer and let it cool, then check the lint filter thoroughly — a severely neglected, tightly packed filter sitting right against the heating element is one of the most common causes of overheating and burning smells.
- For vented dryers, check the external vent hose isn’t crushed or blocked along its full length.
- Check nothing flammable was left in a pocket (a lighter, a receipt) that could be scorching against the drum.
- Check the load wasn’t left running for far longer than needed on a small load, which can sometimes cause fabric to overheat even in a working machine.
⚠️ Stop using it if the smell persists
If the filter is clean, venting is clear, and the smell continues — or if you ever see smoke or scorch marks — stop using the appliance immediately and don’t run it again until a qualified engineer has inspected it. Never leave a tumble dryer running unattended or overnight, and check your specific model against UK safety recall lists if it’s an older machine, since several tumble dryer models have been subject to genuine safety recalls in past years.
