This 3/4-inch high limit control switch is a vital safety component for residential furnaces and heating systems. Designed as a disc-style thermal sensor, it monitors internal temperatures to protect your HVAC equipment from overheating. The L160-20F specification signifies a 160°F opening point, where the switch will automatically break the electrical circuit if the temperature exceeds safe limits, and a 20°F differential for resetting. Replacing a malfunctioning limit switch is essential for restoring proper furnace cycles and ensuring the safe operation of your home heating appliance. It is a common repair part for central gas and electric furnaces that are short-cycling or failing to blow warm air.
