The Thorn Thermo couple also known as the thermocoupling, when you start the pilot, you need to manually depress the gas valve for 10 to 20 seconds to provide the thermocouple a period of time to heat up and begin generating enough current to keep the gas valve open. If the pilot won't stay lit regardless of how long you depress the gas valve, the thermocouple could possibly be broken. You can test the thermocouple by disconnecting it from the gas valve and measuring the voltage between the conductors. You should get a reading of around 40 millivolts when the pilot flame is on. A reading of less than 25 millivolts signifies that the thermocouple is usually defective and needs to be changed., Main Thermocouples Are Dispatched Same Day, For Next Working Day Delivery
