Is it dangerous if pilot light goes out on gas fireplace?

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.

.

Similarly, you may ask, 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.

Subsequently, question is, will gas shut off if pilot light goes out? It should be turned off, and must be turned off to allow the pilot to be relighted, but there is a safety feature in gas appliances that if the pilot light goes out, a heat operated valve cools off and shuts the gas supply to the pilot light and the main burner.

Keeping this in consideration, why would a pilot light go out on a gas fireplace?

If the thermocouple doesn't get enough heat, the electromagnet inside the valve won't be strong enough to hold the pilot gas open. The coil in the valve releases and the pilot goes out. It is also possible that the thermocouple is getting old and isn't producing as much voltage anymore.

Does gas leak if pilot light goes out?

When the pilot light goes out, it does not leak carbon monoxide gas. However, if the light goes out frequently there could be other issues.

Related Question Answers

Can you get carbon monoxide poisoning from a pilot light?

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.

Does the gas shut off when pilot light goes out?

Use of a pilot generator or a thermocouple in the flame provides heating appliance safety as it generates enough electric current from the burning flame to hold the gas valve open. If the pilot light goes out, the pilot generator cools off and the current stops, closing the gas valve.

Should the pilot light always be on in a gas fireplace?

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.

How do you troubleshoot a gas fireplace?

To do this, hold the pilot button down for about one to three minutes while the air bleeds out. Step 3. If gas is coming out of the pilot, but it still won't light, the spark igniter could be the problem. Alleyne says to look for and clear out any debris between the igniter and thermocouple.

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 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.

Is it dangerous to light a pilot light?

Yes, it is safe to light a pilot light with a gas lighter. First of all, make sure that your hands or clothes are not in contact with the burner. Then, turn the burner knob to the 'pilot' position. If you follow these instructions, it is safe to light a pilot light using gas lighter.

How do you know if your pilot light is out?

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.

How much does it cost to replace a thermocouple?

Thermocouple Replacement - $20-$150 Calling a professional plumber to install a new thermocouple should only be up to $150. If you do the work yourself, you will only pay the price of the part which is about $20.

How do you relight a pilot light?

Relight the pilot light. Turn the knob to “Pilot,” and let gas to flow to the pilot. Light a lighter or match, then push in the reset button. Hold your flame to the pilot light's opening. Keep the reset switch depressed until the pilot light is burning steadily.

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 is my gas fireplace not turning on?

1. 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. If gas is coming out of the pilot, but it still won't light, the spark igniter could be the problem. Look for and clear out any debris between the igniter and thermocouple.

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.

How do you test a thermocouple?

Steps

1. Locate the pilot light controls on the gas valve.
2. Turn the pilot light on for 30 seconds.
3. Release the button to see if the pilot light goes out.
4. Turn off the gas supply to test the thermocouple again.
5. Count to 20 and wait for the pilot light to go out.
6. Listen for clicking near the gas valve.

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.

Why would a gas fireplace suddenly go out?

If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a "lazy" flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.

How do I know if my gas fireplace is working?

You should:

1. Inspect the glass doors for cracks or latch issues.
2. Check that gas logs are in the proper position.
3. Turn gas off at the shut-off valve and test the igniter.
4. Ignite the fire and look for clogged burner holes. If present, turn off gas and clear obstructions with a pin or needle.

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.

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.
