A burning smell from a tumble dryer should never be ignored. Even if the machine is still working, the smell is a warning. It usually means something is overheating, rubbing, or failing electrically.
This is one of the few dryer faults that can become dangerous if left unresolved.
What the smell usually means
Different smells point to different problems. Engineers pay close attention to how the smell is described.
- Burnt rubber smell often means a slipping belt
- Sharp electrical smell can indicate wiring damage
- Hot plastic smell may come from overheating components
- Musty burnt lint smell can come from blocked airflow
All of these require inspection.
Common causes of burning smells
- Blocked lint filters and vents
- Worn or slipping drive belt
- Overheating motor
- Faulty heating element
- Damaged wiring
- Seized drum rollers
Lint is extremely flammable. When airflow is restricted, heat builds up rapidly.
Typical UK repair costs
- Full internal clean and service: £60 to £110
- Drive belt replacement: £60 to £110
- Drum roller replacement: £90 to £160
- Motor replacement: £160 to £280
- Heating element replacement: £110 to £190
- Wiring repair: £70 to £140
- Call-out fee: £40 to £70
Most burning smell faults are resolved for between £90 and £180.
Why this fault escalates quickly
Heat damages nearby parts. Rubber hardens. Plastic warps. Wiring insulation cracks. What begins as friction can turn into electrical failure.
That is why burning smells should be treated urgently.
Is it safe to use the dryer
No. If you smell burning, stop using the machine. Unplug it. Do not run another cycle.
Continuing to use it risks fire, motor burnout, or severe electrical damage.
Is repair usually worth it
In most cases, yes. Burning smells are often caused by mechanical friction or lint buildup, not catastrophic electrical failure.
Only if the control board and motor are both damaged does replacement become likely.
How engineers find the source
Engineers inspect all moving parts, check belt tension, test motor temperatures, and examine wiring. They also clean internal lint deposits that are not accessible without disassembly.
This is why professional diagnosis matters.
