The Gas Shutoff Switch is an important switch in your Max-E-Therm or MasterTemp pool heater, and is used to detect when your heat exchanger outlet temperature has exceeded a safe level (140°F) and the switch immediately opens when that happens. Your MasterTemp heater will indicate when it is time to replace the High Limit Switch when the "AGS" LED is displayed.
