Correspondingly, what causes a pilot light to go out on a gas fireplace?
If the pilot light on your gas fireplace won't stay lit, a very likely culprit is a component called a thermocouple. The thermocouple is a metal rod that sticks out right in front of the pilot itself. It senses if flame is present or not. If the pilot light is lit, it heats up the thermocouple.
One may also ask, is it OK to leave pilot light on gas fireplace? 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.
Furthermore, 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.
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.
Related Question AnswersWhy does my gas fireplace not turn on?
Pilot light systems are the most common reason gas fireplaces fail to light, so check the main gas valve to make sure the gas is turned on. It should usually run parallel to the gas line when it is on. The pilot lights, but not staying lit, indicates that the thermocouple is worn out or bad.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.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 test a thermocouple?
Steps- 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.
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.Do gas fireplaces need to be serviced?
The initial and foremost guideline of any gas fireplace system is to have it inspected every year. With professional chimney companies, you can usually have your annual chimney cleaning and gas inspection scheduled at the same time. Matter of fact, your whole system should be inspected annually, top to bottom.Will gas leak if the pilot light goes out?
Carbon monoxide is a colorless, odorless gas produced during burning fuel. It doesn't leak from a pilot light that's gone out, but if the light keeps going out even after you relight the pilot, it can indicate that you have other problems.Is it safe to relight a pilot light?
Yes, it is safe to light a pilot light with a gas lighter. If you are trying to relight the pilot light, before turning the knob to the pilot position, wait for some time until the gas smell goes away. If you follow these instructions, it is safe to light a pilot light using gas lighter.What do you do if the pilot light goes out?
How to Relight a Pilot Light- Turn off your appliance at the power switch or thermostat.
- Find the gas valve control knob and turn it to select “pilot.”
- If pilot light controls are sticky, do not apply force or use oil.
- Press the red button while simultaneously holding a match to the pilot burner.
What would cause a 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. 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.How much is a thermocouple?
The No. 1 cause of pilot lights that won't stay lit is a worn-out thermocouple. It's easy to replace and a new one costs $5 to $10. Rather than trying to unfasten the thermocouple inside the water heater's burning chamber, it's easier to remove the whole burner and thermocouple assembly.How do you fix a thermocouple?
A burned out or broken thermocouple should be replaced. To replace a thermocouple: Step 1: Unscrew the copper lead and the connection nut inside the threaded connection to the gas line. Step 2: Under the mounting bracket at the thermocouple tube, unscrew the bracket nut that holds the tube in place.Are thermocouples universal?
Universal Thermocouples. Universal thermocouples, as the name implies work on most water heaters. They are available online and in home supply stores for a reasonable cost. The length and the thread type are the two concerns when purchasing one.Should the flame touch the thermocouple?
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.What causes a weak pilot light?
Some of the reasons your pilot light keeps going out include: High winds or downdraft. A poor pilot flame - low gas pressure or blocked orifice. A flame that is set too small.What color should the pilot light flame be?
blueWhy 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.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.How do you adjust the pilot light flame?
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.
- Rotate the screw on the pilot light clockwise, and the size of the flame will decrease.
