WebJan 17, 2010 · A thermocouple or flame sensor is a device used to control gas flow in gas water heaters. On older heaters with standing pilot … WebSep 24, 2024 · A standing pilot is one that is always burning, and the job of a thermocouple is to shut off the gas if the pilot goes out. A gas furnace has an electronic igniter instead of a standing pilot, so it doesn't need a thermocouple. Instead, the flame sensor is positioned directly over the burner, and its job is to detect the burner flame.

WebThermocouple flame detection [ edit] Thermocouples are used extensively for monitoring flame presence in combustion heating systems and gas cookers. A common use in … WebFeb 17, 2006 · Its purpose is to provide the flame needed to light the gas coming out of the main burner. When the furnace "turns on", a valve releases gas into the burner and the pilot light ignites that gas. The way that a pilot light is created is also simple. It is made by allowing a small amount of gas to come from the gas pipe through a small tube.
WebA thermocouple, on a gas appliance, signals the gas valve that the pilot is lit so it will remain open. The thermocouple is positioned in the middle of the pilot flame. It detects the heat of the flame and generates the voltage that keeps the gas flowing. If the flame goes out, the thermocouple voltage disappears and closes the gas valve.
WebMay 16, 2024 · Because the thermocouple shuts off the gas supply when it doesn’t sense a flame, it prevents your furnace from receiving any gas when the pilot light is out. This restricts gas from building up in your furnace and makes your system much safer because it will prevent explosions and carbon monoxide leaks (discussed above). how many dollars are 500 eurosWebNov 14, 2009 · Flame sensors and thermocouples are simple parts that wear out and fail over time, and most are easy to replace. … how many dollars are hilton points worthWebIf the pilot flame ignites but goes out after you release the gas control knob, the cause may be a dirty or defective thermocouple.
