Rheem-Ruud 47-20045-03 Limit Switch this HVAC safety switch is

this HVAC safety switch is calibrated to provide high-limit protection by breaking the electrical circuit to the gas valve or ignition control if internal temperatures exceed factory safety thresholds

This switch is designed to trip (open) at 160°F and automatically reset (close) once the temperature drops by 30°F

verifying the underlying cause of a trip—such as restricted airflow or burner malfunction—is essential before utilizing the manual reset button to restore operation

This Fenwal ignition cable utilizes industrial-grade insulation capable of withstanding the extreme temperatures associated with commercial combustion chambers
