Why Replace Your Fan Gasket?
Over time, fan gaskets can degrade due to heat cycling, condensation, and normal wear. A compromised gasket can allow flue gases to escape into the equipment cabinet, reduce combustion efficiency, and trigger safety lockouts. Replacing the fan gasket with a genuine OEM part ensures the appliance continues to operate safely and at peak performance.
