Where is the pilot light on my heater?
Near the bottom of your furnace is a switch that normally says “Pilot,” “On” and “Off.” Find this switch and turn it to the “Off” position.
Do heaters use a pilot light?
If you have an older gas furnace, your heating unit relies on a little blue flame known as a pilot light to ensure ignition of the burners. Water heaters, gas fireplaces and old gas stoves also often have similar pilot lights. Pilot lights can develop problems that cause them to burn inefficiently.
How do I know if my pilot light is out on my furnace?
Remove the front cover panel on your furnace. This should expose the pilot, which simply looks like a small single burner, kind of like a candle or if you only had a single flame lit on a gas stove. If there is no flame, then the pilot is out.
What happens when pilot light goes out?
The pilot light is a small gas flame that stays lit all the time. When the thermocouple senses a lit pilot, it leaves the main gas valve open. If the pilot light is out, or isn’t burning hot enough, it closes the valve, cutting off gas flow so it won’t build up inside your house.
Why is my pilot light not staying lit on my furnace?
Some common causes include issues with the thermocouple and pilot tube. The thermocouple detects the pilot light via sensors. A dirty pilot tube can also prevent the pilot from staying lit. If the pilot tube is dirty, let the furnace cool down and turn off the gas.
Why is my furnace blowing cold air?
Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off so that the heat exchanger does not crack.
Should the pilot light always be on in a gas heater?
Should the pilot light always be on in a gas fireplace? Most gas fireplaces rely on a “continuous pilot light,” a type of pilot that remains lit so long as gas is flowing to the unit. If you have a continuous pilot light system, you should always see a pilot flame unless you have manually turned the system off.
Do I need to turn gas off if pilot light goes out?
If the pilot light goes out, you can relight it after the gas is shut off using a match or the unit’s electronic ignitor if it has one, following the proper safety precautions. If your gas is shut off, turn the gas shutoff valves on all gas appliances to the “off” position until the gas service is restored.
Does gas turn off when pilot goes out?
Your pilot light relies on your natural gas to stay aflame, so if your gas is shut off, your pilot light will go out. Simply turn your gas back on and either relight your pilot light yourself or call a professional.
Is it safe to relight a pilot light?
But first, some words of caution: –Don’t relight the pilot light if there is a strong gas odor. Close the main gas shut-off valve for your house or for the appliance with the leak and call the gas company immediately. Get everyone out of the house until the problem is corrected by gas company technicians.
