Is It Dangerous If The Pilot Light Goes Out On Furnace?

by | Last updated on January 24, 2024

, , , ,

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.

Do I need to turn gas off if pilot light goes out?

Since the thermocouple regulates gas going to the pilot,

it should cut off on its own if the pilot ever goes out

, but that’s only if it’s functioning correctly. If the thermocouple isn’t working properly, then it’s possible that it’s allowing gas to leak into the very room where the heater is located.

Is it dangerous for pilot light to be out?

A pilot light may need to be re-lit from time to time after being extinguished on purpose or by accident. If it is accidentally extinguished,

there exists a danger that the gas used to keep the flame lit will continue to vent

, possibly into the living space.

What happens if the pilot light goes out on furnace?

If your pilot light goes out,

your furnace will not be able to produce heat because its burners will not ignite

. Often, homeowners can relight the pilot themselves.

Can you get carbon monoxide poisoning from a pilot light?


A yellow or orange pilot light will produce carbon monoxide

– an odourless, colourless gas that can fill your home and cause carbon monoxide poisoning. Symptoms of this condition include dizziness, headache, fatigue, nausea, unconsciousness, brain damage and death.

Why would pilot light go out?

Some of the possible serious reasons for pilot lights to go out include

loose or broken gas valves, thermocouples or heat exchangers

, faulty venting, low gas pressure, or high winds. If you believe there is a serious problem, don’t hesitate to contact a professional.

What do you do when the pilot light goes out on a gas fireplace?

If you notice your pilot light has gone out, the first thing you should do is

shut off the gas feed and wait a few minutes

.

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

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.

Can you smell gas from a pilot light?

Note that

it is totally normal on automatic pilots

(pilots that do NOT stay lit all the time) to smell a little natural gas when the are first turned on. A little gas will escape as the pilot and burners light on your heat or appliance.

How much carbon monoxide does a pilot light produce?

Also, a typical pilot light can generate

450 pounds of carbon dioxide

– a greenhouse gas — over a six-month period. If an appliance isn’t needed for a long period of time, its pilot light may be extinguished to save energy, reduce greenhouse gas emissions, and reduce the risk of fire or explosion.

Does the pilot light always stay on?

A pilot light means heat, and it also means fuel usage. That flame doesn’t stay ignited by magic – it needs gas. Which means as long

as that

light is on, you’re using your fuel supply to maintain it.

How do I stop my furnace pilot from blowing the wind?

You can prevent a faulty pilot light from wind by

fixing your thermocouple, gas release

, protecting against downdrafts, capping your chimney, and checking your firebox cover.

Is it OK to leave pilot light on gas fireplace overnight?

If you leave the pilot light on for long periods without turning on the main burner,

a white film can develop on the glass

. This is a sulfur byproduct of the burning pilot, and if left uncleaned, it can etch the glass.

What does carbon monoxide smell like?

No,

carbon monoxide has no smell

. Carbon monoxide is an odorless, colorless gas that’s a byproduct of combustion. As a homeowner, this means it can leak from your gas furnace, stove, dryer, and water heater as well as wood stove/fireplace.

What are the symptoms of gas leak?

  • Ringing in your ears.
  • A reduced appetite.
  • Pain in the chest.
  • Nosebleeds.
  • Blistering or pale skin.
  • Flu-like symptoms.
  • Dizziness.
  • Breathing difficulties.

Does carbon monoxide detect gas leak?

Will a carbon monoxide detector detect a gas leak? Technically speaking, a carbon monoxide detector

is not designed to detect the presence of gas

. Instead, these devices alert for elevated levels of carbon monoxide in the air that could be the result of toxic gases or air quality issues.

How much heat does a pilot light give off?

Just how much gas does a pilot light consume? Most pilot lights will consume

about 600 BTU’s of gas/hour

. With 24 hours in a day, that’s roughly 14,400/BTU’s each day.

How much does it cost to run a gas pilot light?

The average fuel consumption of your standing Pilot light is: Natural gas is $0.60 a day =

$219 a year

. Liquid Propane is $1.80 a day = $657 a year.

Can you get carbon monoxide poisoning from a gas fireplace?


Yes, gas fireplaces are one potential cause of carbon monoxide poisoning

. … An improperly maintained or ventilated gas fireplace can create incomplete combustion, creating carbon monoxide, and causing this toxic gas to linger—putting those inside at risk of carbon monoxide poisoning.

Should the pilot light always be on 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. But if the pilot flame goes out, then the gas would still be released. After a while, the gas could collect in your home and become a health hazard.

Why does my pilot light go out on windy days?

If the water heater pilot blows out when windy, then

the thermocouple

is might be responsible for that. It is the flame sensor and maintaining the flame is its responsibility. Due to excessive use, the device can be dirty, broken, or misaligned. … A faulty thermocouple doesn’t see the flame and cut off the gas supply.

How long do thermocouples last?

How to Tell if You Have a Bad Thermocouple? Thermocouples can last

up to 10 years

if properly installed and maintained, while furnaces can last 15-20 years, although either may wear out sooner in multifamily units.

Can opening a window stop carbon monoxide poisoning?

If it’s in your bedroom, you’ve got problems, whether you have a window slightly open or not. Rule Number 1. If the CO detector alarms, evacuate the home! Just because you have a

window open does NOT mean

that carbon monoxide will head for the window and leave your bedroom.

How do you check for carbon monoxide without a detector?


Sooty or brownish-yellow stains around the leaking appliance

.

Stale

, stuffy, or smelly air, like the smell of something burning or overheating. Soot, smoke, fumes, or back-draft in the house from a chimney, fireplace, or other fuel burning equipment. The lack of an upward draft in chimney flue.

How long does it take to get carbon monoxide poisoning?

If the carbon monoxide concentration in the air is much higher, signs of poisoning may occur

within 1-2 hours

. A very high carbon monoxide concentration can even kill an exposed individual within 5 minutes.
