This 5-inch high limit switch is an essential safety component for forced-air heating systems and furnaces. Designed to monitor the internal temperature of the heat exchanger, this thermal limit control prevents the appliance from overheating by automatically breaking the electrical circuit if the temperature exceeds safe operating limits. Featuring a 145-degree Fahrenheit cut-out and a 30-degree differential for a reset at 115-degrees, this switch ensures reliable furnace performance and protects against equipment damage. If your HVAC system is experiencing short-cycling or the blower fan is running continuously, a replacement high-limit sensor may be necessary to restore proper heating cycles and home safety.
