This premium 230F manual reset limit switch is a vital safety component designed for high-efficiency gas furnaces and HVAC systems. Functioning as a high-limit control, this thermal disc monitors the temperature within the heat exchanger cabinet. If the internal temperature exceeds the safe threshold of 230 degrees Fahrenheit, the switch trips and breaks the electrical circuit, instantly shutting down the heating process to prevent equipment damage or fire hazards. The manual reset feature ensures that the system cannot restart until a technician or homeowner has inspected the unit and manually cleared the fault, providing an extra layer of protection against persistent overheating issues caused by restricted airflow or mechanical failure. Engineered for durability and precision, this switch is a direct replacement for heating units requiring a 230-degree thermal cutout.
