The L155-22 High Limit Switch is a vital safety component designed for HVAC systems, including furnaces and heat pumps. This fan disc-style thermostat acts as a thermal safeguard, monitoring the internal temperature of the appliance to prevent overheating. When the air temperature exceeds the safe operating threshold of 155 degrees Fahrenheit, the switch automatically interrupts the electrical circuit to shut down the heating element or burner, protecting the system from damage and ensuring home safety. This replacement limit control is essential for restoring proper heating cycles and resolving issues where a furnace may be short-cycling or failing to provide heat due to a faulty thermal sensor.
