The 170F-40 Auto Limit Switch is a critical safety component designed for Goodman and Amana gas furnaces and HVAC systems. This high-limit control switch monitors the temperature within the heat exchanger or blower housing to prevent overheating. If internal temperatures exceed the safe operating threshold of 170 degrees Fahrenheit, the switch automatically breaks the electrical circuit to shut down the heating element or burner, protecting your equipment from damage and ensuring home safety. As an auto-reset fan disc, it restores the circuit once the system cools down to a safe level. This replacement part is ideal for restoring proper furnace cycling and resolving issues where the blower runs continuously or the furnace fails to ignite due to a faulty safety sensor.
