This green-coded safety control helps protect heating systems by monitoring supply air temperature and automatically interrupting operation if dangerous overheating conditions occur.

• Automatic reset design eliminates need for manual intervention after temperature returns to safe levels
• Green color designation for easy identification during service and replacement
• OEM Bard part ensuring proper fit and function in Bard heating equipment

This limit switch is a critical safety component that protects the heat exchanger and cabinet from excessive temperatures caused by restricted airflow, blower failure, or other system issues. When troubleshooting short cycling on heat or high limit trips, replacing a worn or out-of-calibration limit switch with the genuine Bard 8402-145BX ensures reliable safety operation and proper equipment protection. The BX suffix indicates this part comes packaged in a box for aftermarket service use.
