Differential
Likely causes of “Dryer has a burning smell”, and how to tell them apart
- 1
Lint has built up around the heater or in the exhaust
What separates it A hot lint smell that grows with use, and dry times are long.
How to confirm With power off and the dryer cool, remove visible lint from customer-accessible areas and the lint trap housing.
- 2
A coin, tissue or garment is caught against a hot part
What separates it A smell of burnt paper or fabric after a load, and an item is stuck near the drum edge.
How to confirm Check the drum and the gap around it for trapped items.
- 3
A damaged cord, plug or outlet is overheating
What separates it A plastic or electrical smell, and the plug or the outlet is warm or discolored.
How to confirm Look at the cord and plug without touching hot parts.
- 4
An internal wiring or motor fault
What separates it An electrical smell from the cabinet or with smoke, and the dryer trips the breaker.
How to confirm This is a stop condition; do not run another test cycle.
Before you touch a setting
Record this first — changing settings destroys the evidence
- Where the smell came from: the drum, the exhaust, the cord or the cabinet.
- Whether there was smoke or unusual heat.
- What the load was and how long the dryer had been running.
