How does thermocouple work on gas valve
WebThermocouples for boilers, hot water systems, heating sensors and ovens work in much the same way as they would for a thermostat, as outlined above. Gas varieties of these appliances in particular often incorporate thermocouples as safety features, preventing gas valves from opening if the heat from a lit pilot light isn’t generating the ... WebFeb 17, 2006 · The electricity that is created runs to a small electromagnetic valve and holds it open. If the pilot light blows out, the thermocouple quickly cools off. It stops generating electricity and the valve closes. To relight the pilot light, you have to push a button that opens the value manually.
