The 3" High Limit Switch L175-20F is an essential safety component designed for heating systems and large appliances. This thermal limit control acts as a critical fail-safe, monitoring internal temperatures to prevent overheating and potential equipment damage. Specifically engineered to open the electrical circuit when temperatures reach 175 degrees Fahrenheit and reset once the temperature drops by a 20-degree differential, it ensures your heating unit operates within safe parameters. Ideal for HVAC maintenance and appliance repair, this high-limit thermostat is built for durability and precision in high-heat environments. Replacing a faulty limit switch is a vital step in restoring the safety and efficiency of your furnace or heating assembly.
