• 8" FAN/LIMIT CONTROL

The Bard 8402-045 8 inch fan/limit control is an OEM temperature-sensing control used in Bard heating and gas/electric wall mounted equipment to manage indoor blower fan operation while also providing a high limit safety shutdown if the supply air temperature climbs too high. With its 8 inch insertion element, it mounts in the airstream where it can accurately respond to heat rise, helping prevent short cycling, overheating, and nuisance lockouts caused by a drifting or failed limit. When replacing Bard 8402-045, confirm insertion length, temperature setpoints, and terminal wiring match your existing control and the unit wiring diagram to restore proper fan timing and safe heat operation.
