How to Adjust the Pilot Light Flame on a Gas FurnaceLocate 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. Rotate the screw on the pilot light clockwise, and the size of the flame will decrease.
Locate the pilot light controls on the gas valve. Turn the pilot light on for 30 seconds. Release the button to see if the pilot light goes out. Turn off the gas supply to test the thermocouple again. Count to 20 and wait for the pilot light to go out. Listen for clicking near the gas valve.
Regarding this, 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.
Likewise, is my pilot light too high? A: There is a way to control the height of the pilot light flame. The pilot flame should touch the thermocouple at a specific level. If the flame is blue and weak, and barely reaches the thermocouple, it needs to be stronger. If it extends well above the thermocouple, it's too strong.
Keeping this in view, where is the pilot light adjustment screw?
The pilot adjustment screw is located on the gas valve, just “above” the pilot tube (See Figure 3). Remove the cap screw and find the actual adjustment screw behind it. Turn the screw in to decrease pilot flame, out to increase.
How do you turn a pilot light off?
Pilot Light Outage If the pilot light goes out completely, turn the pilot light control knob to the pilot position and push the knob in while lighting the pilot with a match or torch lighter. Continue to hold the knob in until you see that the pilot is staying lit.
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.What causes a weak pilot light?
That can be caused by numerous things, but a few of them are: lint or dirt buildup in the air inlet screen, crud in the gas valve that is preventing the proper amount of gas to get to the pilot, soot accumulation on the thermocouple, a poor connection of the thermocouple to the control, or a bad thermocouple.What color should the pilot light flame be?
blueShould the fireplace pilot light always be on?
Electronic ignition is when the pilot light on a gas fireplace/insert/stove is only running when the fireplace is on, this means that the unit is likely to have a battery backup as well. A standing pilot is always on, always using a small amount of gas to run constantly unless the gas is physically turned off.Are pilot lights supposed to stay on?
At the same time, that pilot light is burning off the gas and preventing the poisonous fumes from entering your home. Some pilot light tubes have automatic shut-offs if the flame goes out, but not all of them do, so each and every pilot light in the home should be routinely checked to make sure it is always on.Why does my pilot light go out when I release the pilot light knob?
The most likely of those is that the thermocouple needs to be replaced. The button you press to light the pilot bypasses the thermocouple. When you release the button, the thermocouple ensures that unburned gas doesn't get released by shutting off the gas when it's not heated by the burning pilot light.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.How do you test a thermocouple?
StepsHow do you adjust a thermocouple?
To adjust the thermocouple, you must tighten the thermocouple nut with a wrench. Take care not to apply too much pressure to the nut -- just tighten it slightly. Then try lighting the pilot. If the pilot won't stay lit, replace the thermocouple with a new one of the same type.Why is my pilot light so loud?
If there is a roaring sound that occurs when the pilot light is on, it is usually because the flame needs to be adjusted. A grinding or shrieking noise is usually caused by a fan or blower. Not all gas fireplaces have this feature.Should a thermocouple be in the flame?
Typically the thermocouple sensor is mounted right in the flame of the pilot light on gas fired heating equipment. But not all of these systems use a thermocouple. Some gas fired heating equipment relies on an electronic ignition to ignite the flame. Those devices generally will not use a thermocouple.How do you clean a gas orifice pilot?
Preparing the Orifice for Cleaning Loosen any nuts that hold the tube or orifice together or attaches it to the appliance. Pliers can work well in small or narrow areas. With an adjustable wrench, gently remove the thermocouple and the pilot tube from the gas supply valve.What is the point of a pilot light?
A pilot light is a small flame that is kept alight constantly in order to serve as an ignition source for a gas burner. They are used on many natural gas and propane appliances, such as water heaters, clothes dryers, central heating systems, fireplaces and stoves.Can a pilot light cause carbon monoxide?
Carbon monoxide is only produced when fuel of any type; oil, gas, wood or coal is burned. And a pilot light out of adjustment can produce carbon monoxide gas. The amount produced by even a badly maladjusted pilot is small because the flame size is also small.What does a thermocouple look like?
The thermocouple looks like a piece of metal tubing smaller than a soda straw. To find it, first locate the gas control box. This is the box that the main gas line enters, where you turn the gas on in the furnace. The other end of the thermocouple sits in the flame of the pilot light.How do I check my pilot light?
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.Can you clean a thermocouple?
If the Thermocouple is faulty it will cause the unit to shut down. How to clean? Remove Thermocouple from pilot assembly, using steel wool or emery cloth to lightly clean the tip removing any soot or build up that might have accorded due to an improper pilot flame.ncG1vNJzZmiemaOxorrYmqWsr5Wne6S7zGifqK9dmbxuxc6uZJqcmqrAtXnAZqeipJ%2Bpeq21xqGr
