Amana-Goodman B1370189 Limit Switch the red color denotes aThe Amana Goodman B1370189 Limit Switch is a critical safety component designed for specific residential gas furnaces and heat pump systems. This 170 200F auto limit switch functions as a high limit safety control, monitoring the heat exchanger temperature to prevent overheating. When temperatures exceed the 200F threshold, the switch opens the circuit to the gas valve, shutting down combustion until the plenum cools to 170F, at which point it
