On Gas cookers, Thermocouples are used as safety switches to control the gas supply.
Cookers fitted with Thermocouples required the user to keep the gas tap depressed during the first 10 to 20 seconds of lighting the cooker. This allows the Thermocouple to heat up and generate an electric current which opens an electromagnet valve. As long as the current flows, the valve is held open allowing the gas to reach the appliance. If the flame fails, the measuring junction cools stopping the flow of current and the electromagnet releases the valve, shutting off the gas.
The typical symptom for a Thermocouple is that the oven will ignite but the flame will extinguish rather than stay lit as you would normally expect after depressing the gas tap.
