Tumble Dryer Smells Burning

Blocked Lint Filter or Lint Build-Up

The most common cause. A heavily blocked filter causes the machine to overheat, which can cause lint to scorch and produce a burning smell. The filter must be cleaned after every single cycle. Lint can also accumulate inside the machine over time.

Blocked Exhaust Duct (vented dryers only)

A blocked or kinked exhaust duct traps hot air inside the machine, causing overheating and a burning smell. Check and clean the duct regularly and ensure it has no sharp bends.

Item Touching the Heating Element

A small item of clothing or foreign object that has escaped the drum and come into contact with the heating element will produce a burning smell. Check inside the drum and the lint filter housing carefully.

Worn Drive Belt

A worn or slipping drive belt can produce a burning rubber smell as it slips against the drum or motor pulley. Requires professional inspection and replacement.

Worn Drum Glides or Bearings

Worn drum glides or rear bearings can produce a burning or acrid smell as they overheat from friction during the cycle. Requires professional diagnosis and replacement.

Electrical Fault

A sharp or acrid burning smell can indicate a fault with the motor, control board or wiring. Do not use the machine again until it has been inspected by a qualified engineer. This is a potential fire risk.

New Machine Smell

A mild burning smell during the first one or two cycles of a brand new dryer is normal — it is caused by manufacturing residues burning off. This should clear quickly and not persist beyond the first couple of uses.

Clean the Lint Filter Thoroughly

Remove the lint filter and clean it completely. Check inside the filter housing for any build-up of lint that may have accumulated around the heating element area.

Check the Drum for Foreign Objects

Remove all laundry and check inside the drum for any items that should not be there — particularly near the drum seal and at the back of the drum.

Check the Exhaust Duct

Inspect the exhaust duct for any blockages or kinks. Clean out any lint accumulation inside the duct and ensure it is routed as directly as possible to the outside.
