Application
This limit switch is a critical safety component in York forced-air furnaces. It is mounted on or near the heat exchanger and continuously monitors operating temperatures. If airflow is restricted, a filter becomes clogged, or another fault causes temperatures to rise beyond the safe threshold, the switch opens the burner circuit to prevent equipment damage or fire hazard. The auto-reset feature allows the system to resume normal operation once conditions normalize, reducing service calls and downtime.
