Application
This limit switch is a critical safety component in forced-air furnace systems. When airflow is restricted or the heat exchanger overheats, the limit switch opens the burner control circuit to prevent damage or hazardous conditions. The automatic reset feature means the system will resume normal operation once temperatures normalize — no manual intervention required. Always verify compatibility with your specific model before installation.
