Furnace emits a chemical or metallic odor when heating

Safety: Turn off the furnace and ventilate the area if you notice strong chemical odors.

• 1. Remove chemicals: Do not store paints, solvents, or cleaners near the furnace. Fumes can be drawn into the combustion air.
• 2. Clear furnace area: Remove any plastic or combustible items from on or around the furnace cabinet.
• 3. Motor check: Listen for unusual motor noises that may indicate overheating. If suspected, have a technician inspect and replace the motor if necessary.
