The pilot light needs air to burn, but not too much nor too little. Too much air, in the form of a draft, will cause the pilot to flicker and may blow it out. The draft may be coming from under a door or through a poorly-sealed window, or the draft may be intermittent, occurring only when a door or window is open.
Why is my gas heater flickering?
Flickering Yellow Flame This could be caused by a loose connection or damaged tube. As the air flows into the line, the flame is not able to burn enough gas to burn hot and steady. Second, the furnace’s thermocouple may be broken. This part of your furnace regulates the amount of gas that feeds the pilot.
What causes a weak pilot flame?
Some of the reasons your pilot light keeps going out include: … A poor pilot flame – low gas pressure or blocked orifice. A flame that is set too small. An insufficient supply of gas.
Should a pilot light be orange?
The flames from traditional pilot lights should burn a bright blue color. If your pilot light’s flame is orange or yellow, it is burning inefficiently due to a lack of oxygen. The thermocouple should sense when this happens because the heat from the flame will not be as hot as it should be.Is my pilot light too high?
Next to the “Pilot” indicator on the furnace’s control switch, there is a small screw located near the pilot light-thermocouple assembly. … If it extends well above the thermocouple, it’s too strong. If the flame covers the top of the thermocouple and burns steadily with a yellow tip, that’s just about right.
Should the pilot light always be on in a gas heater?
Leaving the gas on keeps this compound moving out of the tubes. Keeping the pilot light on will also keep moisture out of the unit and in turn, help prevent corrosion. … As you can see, it’s probably best in most cases to extinguish the pilot light in your gas fireplace during the months when you don’t need heat.
What color should a pilot light be?
The color of the pilot light should be blue because that means that only natural gas—without any other condensates—is reaching the pilot light through the gas main. The principal chemical compound found in natural gas is methane, and methane burns blue.

How do you fix a weak pilot flame?
The cause of a weak flame may also be an obstruction in the pilot tube. You can often remove such obstructions by turning off the gas, unscrewing the pilot tube from the valve control and blowing compressed air from a can through the tube. You can also poke the aperture of the pilot tube with a needle.
What are the symptoms of 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.
How can you tell if a thermocouple is bad?
Place one test lead on the side of the thermocouple and the other to the end that screws into the gas valve. If the thermocouple has proper continuity, a small resistance reading should be visible on the multimeter. Many multimeters also indicate continuity with an audio alert.

Why is my pilot light so loud?
A – All control valves have a pilot adjustment screw. Turning it clockwise will reduce the flow of gas to the pilot. The optimum adjustment is just before the point it makes noise. … Another cause of excessive pilot noise is that the inlet pressure of the gas supply is too high.
Should the pilot light always be on in a water heater?
The thermocouple’s job is to shut a gas safety valve if the pilot light goes out. That’s important because gas is always being supplied to the pilot to keep the flame lit.
