Hoover carpet cleaner emits a burning smell during use

Safety first: Unplug the unit immediately if you smell burning. Do not continue to operate until the cause is found.

• Check brushes and belt: Remove the brushes and inspect the brush drive belt. Replace if melted, glazed, or cracked. Clear any debris jamming the brushes.
• Inspect for blockages: Check the suction path, filters, and vents for clogs that could cause the motor to overheat.
• Look for scorch marks: Open the housing and inspect wiring and connectors for burnt insulation or discoloration. Any burnt wiring should be repaired or replaced by a professional.
• Test cautiously: After resolving visible issues, run the unit briefly while monitoring for smell. If burning odor returns, discontinue use and have the motor and wiring professionally inspected.
