8402-074 OBSOLETE
- Limit Control L170-7.0
Bard part number 8402-074 is an OEM limit control used as a temperature safety switch in Bard HVAC equipment. This control is commonly referenced as an L170-7.0 limit, meaning it opens on temperature rise around 170 degrees F to help protect the unit from overheating, then resets after the condition is corrected. It is a critical electrical safety component that helps keep the heating circuit operating within design limits, making it a smart replacement anytime you are troubleshooting a nuisance trip, airflow issue, or a confirmed out-of-range limit reading. For proper fit and safe operation, match the part number to your Bard model and verify the wiring and mounting style during installation.
