Once the gas has had time to dissipate, turn the knob to "Pilot." Then, hold down the "Reset" button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button..
Simply so, how do I know if my pilot light is out on my furnace?
The pilot gas line is a small metal tube below the burner assembly and distinctive by the slight upturn at the end. It will be apparent, if the pilot is lit, by the small blue flame burning at the end. If you do not see a small blue flame burning, the pilot light is out.

- Check Your Circuit Breakers. Even if you use a gas or propane furnace, some of the components run on.
- Check Your Thermostat.
- Check the Drain Pan.
- Check Your Air Filter.
- Check the Pilot Light.
- Check Your Natural Gas or Oil Supply.
Also, how do you light a gas furnace with electronic ignition?
The pilot light has a separate small gas line running to it with its own valve. When the furnace comes on, this valve opens, and then the electric spark ignites the pilot. A flame sensor detects that the pilot is lit, opens the valve to the burners, and the pilot light ignites the burners.

Should the pilot light always be on in a gas furnace?
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. Since the pilot light needs to remain active, your furnace is always consuming some gas.How do you know if you have a bad thermocouple?
If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.Can a pilot light flame be adjusted?
Adjusting the Pilot Flame If the pilot flame is too small, you may be able to make it larger by turning the pilot adjustment screw on the valve control counterclockwise with a screwdriver to open it. The cause of a weak flame may also be an obstruction in the pilot tube.Why won t my pilot light light on my furnace?
The pilot light on a gas furnace can go out because of drafts. To relight the pilot, follow the manufacturer's instructions exactly; they are usually fastened to the furnace. Turn gas valve off, and clean opening with piece of fine wire. If it won't stay lit after several attempts, you may have faulty thermocouple.Is it dangerous if your pilot light goes out?
Can a Pilot Light Outage Be Dangerous? The worry here is that when a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be pumping gas. This can mean a buildup of gas, and when the pilot is relit or relights itself it could result in a very serious explosion.Is it dangerous if the pilot light goes out on furnace?
Faulty thermocouple. If your pilot light repeatedly goes out, this is a likely culprit. If this flame sensor should fail, gas will continue to flow even after the pilot light has been extinguished, causing a safety hazard, and requiring immediate repair.Do I need to turn gas off if pilot light goes out?
This system will allow a small amount of gas to leak through the pilot tubing. If the pilot light is out, the gas must be shut off at the appliance isolation valve, normally located in close proximity to the appliance. Then you can follow the manufacturer's instructions to relight the pilot.Why is my boiler not igniting?
Burner won't ignite: This is the most common cause of a boiler failing to provide heat. If the gas jets on the burner will not ignite, no heat will warm up the water in the tank.

Once the gas has had time to dissipate, turn the knob to "Pilot." Then, hold down the "Reset" button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button.What causes the pilot light to go out?
Usually, a problem with the thermocouple causes the pilot light to go out. The thermocouple is the small copper rod that the pilot light hits. That's important because gas is always being supplied to the pilot to keep the flame lit. But if the pilot flame goes out, then the gas would still be released.How do I reset my electronic ignition furnace?
On an electronic-ignition furnace, turn down the thermostat or turn the power switch off and then on again to reset the ignition control module. Listen for the sound of the spark or watch for the hot surface ignitor to glow (see your owner's manual). Next check and clean the furnace's flame sensor.
