Safety First: Immediately stop the dryer, unplug it, and for gas models, shut off the gas. Allow the dryer to cool completely before opening.

Step 1 – Inspect lint filter and housing: Remove the lint screen and clean it thoroughly. Vacuum inside the lint housing.
Step 2 – Open cabinet: Remove the rear panel (and front, if needed) to inspect inside the cabinet. Vacuum all lint from around the heater, motor, and wiring.
Step 3 – Check heating element area: On electric models, inspect the heating element housing for lint or foreign objects touching the element. Clean carefully.
Step 4 – Clean vent system: A restricted vent can cause overheating and burning smells. Clean the entire vent run and exterior hood.
Step 5 – Test cautiously: Reassemble, restore power, and run the dryer on air-only for several minutes. If no smell is present, test with heat while monitoring closely. If the burning smell persists, have a technician inspect for internal electrical issues.

Dryer has a burning smell during operation, sometimes with visible lint inside the cabinet.
