The thermocouple also contains wiring that goes to the gas valve and makes electricity to light the pilot.
Gas heater pilot light keeps going out.
But if the orifice is dirty or restricted the pilot light won t light properly.
The flame will go out if the tube is clogged with dirt or debris.
Either the thermocouple is going bad or it is dirty and needs to be cleaned.
Which means the thermocouple will shut off the gas flow to your furnace as a safety measure.
If the thermocouple fails to shut off the gas all the gas flowing through the furnace could get into your home.
The water heater pilot light is a small flame that ignites the gas burner on your water heater.
Hold it down for at least 30 seconds in order for the thermocouple to get warmed up.
This is the pilot flame that provides the heat.
When the pilot light goes out the loss of current shuts the valve and stops gas flow.
Gas heaters whether they warm up air or water in a home rely on a pilot light to trigger the flame of the actual heater.
Thorough cleaning should do the trick.
When the water heater pilot light goes out first try relighting it following the directions on the water heater label.
Thermocouples work by producing a small amount of voltage when it is heated.
The number one reason why the pilot light keeps going out is the thermocouple.
Repair technicians will need to replace the thermocouple.
To find out if you need a new one turn the gas valve to pilot and then depress the override button.
The pilot light needs a strong flow of gas to make a strong steady blue flame that the thermocouple can sense.
Sometimes it s referred to as the flame sensor it s a safety mechanism that shuts the gas off should the pilot go out.
The thermocouple is the copper rod the pilot flame directly hits.
If this pilot light ever goes out the heater has no way of actually.
The pilot tube supplies gas to the pilot light for combustion.
