8402-078 OBSOLETE
- Limit Control L175-30 7" Standoff
The Bard 8402-078 limit control is an OEM temperature safety switch used in Bard heating sections to monitor supply air temperature and help prevent overheating conditions that can damage components or trip nuisance shutdowns. This is the L175-30 style limit with a 7 inch standoff, commonly used where the sensing element must reach into the airstream while the switch body mounts to the furnace or heater panel. When replacing, match the original mounting depth and temperature rating so your Bard unit cycles safely and consistently, and verify application by model and serial using the unit wiring diagram or parts list before ordering.
