How to Adjust the Pilot Light Flame on a Gas Furnace Locate the access plate on the front of your furnace, and unscrew the screws that are connecting the access plate to your furnace. Observe the flame. Turn that screw counter-clockwise, and the flame should grow.
Can you adjust the pilot light on a furnace?
Adjusting the Flame There is usually a small screw on the pilot valve body that will adjust the standing pilot flame. You may have to refer to the furnace manufacturer’s instructions to find the screw. Turn the screw as needed to adjust the flame throw. A flickering or wavering flame is usually caused by a draft.
Can you adjust the pilot light flame?
On some fireplaces, there will be a “Lo-Hi” button that allows you to adjust the flame upward or downward. On others, there will be a screw that you can easily adjust with a screwdriver. Turning the screw clockwise will lower the flame, while a counterclockwise motion will turn it up.
Where is the pilot light adjustment screw?
The adjustment screw is behind the cap screw. The screw should be turned to decrease the pilot flame.
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.
Why is my pilot light orange?
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.
Should a pilot light make noise?
It is similar to how a gas stove works. If your fireplace’s pilot light is not set the right way, it will produce a whistling sound while working. You must keep your pilot light on a low setting when you first turn it on. After that, slowly increase the light to increase the flame.
How do you fix a yellow pilot light?
If you notice that you pilot light is burning yellow instead of blue, contact Jerry Kelly. The issue can typically be fixed by cleaning out the air intake valve to the pilot light, which should only be done by a professional who knows how to access and repair the part.
How do I make my pilot light higher?
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. If this screw isn’t labeled, consult the appliance owner’s manual to identify it.
What does the pilot screw adjust?
An air screw adjusts how much air is being delivered thru the pilot circuit: in is rich (less air) and out is lean (more air). A fuel screw adjust how much fuel (or air/fuel mixture) is being delivered from the pilot circuit. In is lean (less fuel) and out is rich (more fuel).
Should the pilot light always be on in a gas furnace?
Most furnaces with electronic ignition have a device called a hot surface igniter. The difference is that the flame is only lit (by an electronic spark) when your furnace is ready for a heating cycle. When the pilot light is not needed, it is completely off, saving you money on gas.
How do you set a pilot light?
Turn the gas regulator valve to the “pilot” position. If the water heater has a manual “ignite” button, press that to light the pilot. If it doesn’t have the button, or the button fails, press the regulator valve and hold a grill lighter or long match to the pilot light valve until the pilot ignites.
Why does my pilot light keep going out?
A faulty, misaligned, dirty, or damaged thermocouple is often the culprit behind your pilot light going out. The thermocouple is an automatic safety shutoff device that prevents the gas valve from opening if the pilot light is out.
What does a normal pilot light look like?
Inspecting a Gas Furnace Pilot Light Flame A natural gas flame should be a bright blue color with a small amount of yellow at the very tip. A propane flame will have more of a bluish-green flame with a tinge of yellow at the tip. The flame should strong enough to cover about 1/2 inch at the end of the thermocouple tip.
How do you reset the pilot light on a furnace?
Turn the knob to “Pilot” and hold down the “Reset” button. Using a long lighter, bring the flame close to the pilot opening. This should ignite the pilot light. Once the pilot is lit, you can release the reset button. The pilot should stay lit at this point.
Where should the pilot light hit the thermocouple?
Remove the pilot tube from the gas valve and spray compressed air to clear it. When working properly in most gas appliances, the pilot flame should hit the upper 1/2 to 3/8 of the thermocouple. If the pilot has a weak, orange-yellow flame or barely reaches the thermocouple, it’s too low.
Does gas still flow when pilot light goes out?
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.
What color should the furnace 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.
