Dryer emits a burning smell during operation, with or without visible smoke.

Safety first: Immediately stop the dryer, unplug it, and do not continue using it until the cause is found. Have a fire extinguisher nearby.

• Inspect lint and heater area: Remove rear panel and check for heavy lint accumulation on or near the heater housing. Vacuum carefully.
• Look for burnt fabric: Check inside the drum and around the heater inlet for pieces of fabric that may have contacted hot surfaces.
• Clean exhaust system: Ensure all ducts and vents are clear to prevent overheating.
• Check motor: Smell near the motor area; if the odor is strongest there and the motor is very hot or noisy, it may be failing and should be replaced.
• If any wiring or plastic parts appear melted or charred, discontinue use and contact a qualified technician.
