Perhaps the pilot light is out and the gas has been turned off at the valve.
No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
When pilot light goes out, gas flows out of the pilot light nozzle. If out has continued for a long time, a gas cloud can develop around the furnace. When you go to light the pilot light, you'll ignite this gas cloud and make a big fire ball. If your basement is drafty, you might never get a huge cloud of gas hovering around your furnace. When you notice that your pilot light is out, you should shut off the gas to the furnace and allow any stray gas to dissipate before you turn the gas back on and light the pilot light. alliedallcityinc.com
You may mean a 'thermocouple' - this is a small metal bulb that sends a signal to the gas regulator that the pilot light is on or off. This is a safety feature that will not allow the gas regulator to open if the pilot light is off.
It is supposed to quit burning.
You can but it just has to be done manually..
If you smell gas when the pilot light is lit on a gas heater, it could indicate a potential gas leak. The gas might not be burning completely due to a blocked pilot light or faulty burner, leading to the release of unburned gas. It's important to turn off the gas supply immediately, ventilate the area, and have a professional inspect and repair the heater to prevent any safety hazards.
Same as any hot water heater. Turn the gas valve to off.
No, electric water heaters do not need a pilot light. The heating element is heated by an electric current (similar to the 'eye' on an electric stove or the heaters in a toaster). When the circuit is completed, electric current flows through the element, and it gets hot, and when the electricity is turned off, the element starts cooling. In a gas water heater, the pilot light is a flame, which is always burning. When it's time to heat up the water, the main gas valve is opened, and the pilot light ignites the gas, so that the main burner heats up.
A gas furnace pilot flame stays burning by receiving a constant flow of gas from the pilot light assembly. The pilot light assembly contains a thermocouple that detects the presence of the pilot flame. If the flame goes out, the thermocouple signals the gas valve to shut off, preventing any gas leaks.
Ovens are a great fire risk if the pilot light dies. Immediately turn off the gas if this happens.
No it shouldn't, There is a sensor that turns off the gas if the pilot flame goes out, The only way it would leak gas is if it as a faulty sensor, or a peice of depree gets in the gas line
