How does a pilot light thermocouple work
WebThe thermocouple is a small electrical device, but it is a critical safety component on your furnace. The thermocouple responds to changes in temperature by producing an electrical current that causes the gas valve that supplies the pilot light to open when the temperature is high or to close when there is no direct heat source. WebFeb 12, 2024 · The thermocouple of a gas patio heater is a safety component designed to prevent gas leaks when the pilot goes out. It’s a copper rod that sits next to the pilot tube on the other side of the spark igniter; it allows gas to flow through the pilot tube when it detects heat from the pilot light.

WebReplacing the thermocouple won't solve the problem. You have to be able to light the pilot light first. If you can light the pilot but it doesn't stay lit, after releasing the knob on the gas valve, then try and replace the thermocouple. I've been doing this for over 30 years and I have an idea about how things work WebSep 30, 2024 · Air in the gas line can stop the pilot light from lighting. If you suspect that it’s the cause of the problem, call a professional to expel the air in the gas line. If the thermostat ECO switch is open, replace the thermostat. The gas valve and the internal elements are not working. Replace the entire gas control valve.
WebJan 6, 2024 · A thermocouple fundamentally is an electrical device containing two wires created of various metals joined together. They operated like electrical conductors producing electrical outputs at differing temperatures. The heat comes at one section, circulates, and moves down at each wire. WebStanding Pilot Gas Furnace Sequence of Operation How Gas Furnace Thermocouples Work. with a lit pilot light the thermostat calls for heat and the heating contacts in the thermostat close. the main valve opens and introduces gas to the main burners. The gas touches the pilot flame and is ignited.
WebJan 6, 2024 · When the system is turned on, the pilot in a gas source produces heat, which moves inside the thermocouple. When the heat receives the next junction signal of the thermocouple, it starts to produce the electrical output. The fireplace uses this voltage to run the gas valve section, permitting gas to move and begin a firing process. WebMay 16, 2024 · This rod is connected to your furnace’s gas valve. When your pilot light is lit, the heat from the flame sends a voltage through the thermocouple that keeps the gas line open. If the pilot light goes out, the thermocouple will lose its voltage and the gas line to your furnace will be closed.
WebApr 13, 2024 · The burner rod turns freely, but the pilot rod will only turn when the burner rod is in the off position. All identifying marks have worn off. So I turned the pilot rod in between "off" and "on" and am trying to depress it to light the pilot, but the rod won't depress and the pilot won't light.
