This premium auto-reset limit switch is an essential safety component for HVAC systems and gas-fired unit heaters. Functioning as a high-limit control, it prevents equipment damage and fire hazards by automatically interrupting the electrical circuit if the heater's internal temperature reaches a critical 175°F threshold. Once the temperature drops by the 30°F differential, the switch resets automatically to restore normal operation. Featuring a 3-inch insert for accurate temperature sensing within the air stream or heat exchanger, this component is a common solution for troubleshooting heating units that are overheating or cycling incorrectly. It is built for reliability in both residential and commercial furnace applications.
