Can Wind Blow Out Pilot Light Furnace? Good To Know

Can wind blow out a pilot light furnace? Yes, it can! Strong gusts or bad ventilation systems can create backdrafts that extinguish the flame. To avoid this, check your furnace has proper ventilation and chimney caps to keep out drafts.

Can Wind Blow Out Pilot Light Furnace

If the pilot light keeps blowing out, it could be due to a dirty or faulty thermocouple, gas leak, draft in the room, or insufficient gas pressure. If so, turn off the gas supply at the main control valve and call a professional.

I once had a draft issue near my water heater that kept blowing out the pilot light. I solved the problem by covering the opening with a firebox cover and sealing any gaps and holes with furnace sealant. Since then, my pilot light has stayed lit! 

Knowing how the pilot light works is like having a CPR course for your heating system.

Understanding The Pilot Light in Your Furnace

To understand the pilot light in your furnace’s heating system with components of a pilot light and how a pilot light works. Let’s explore what a pilot light is and how it functions. We’ll discuss the various components of a pilot light and how they work together to ignite the main burner. You will also learn about the process of how a pilot light works, including step-by-step instructions on how to manually relight the pilot light if it goes out.

Components of a Pilot Light in the Furnace

If the pilot light keeps blowing out, it could be due to a dirty or faulty thermocouple, gas leak, draft in the room, or insufficient gas pressure. 

The components include

  1. Thermocouple: Detects the pilot flame and prevents gas leakage by cutting off the flow if the flame goes out.
  2. Pilot burner: This creates a small flame to ignite the main burner.
  3. Pilot orifice: Regulates the flow of gas to the pilot burner and must be clean for proper functioning.
  4. Gas supply pipeline: Delivers fuel to the system and must be without leaks or obstructions.
  5. Control valve: Adjusts the flow of gas to both the pilot and main burners.
  6. Ignition mechanism: Some newer models use electric spark devices instead of standing pilots for ignition.

Note that while most modern appliances don’t have a visible flame, older ones may use a standing pilot light. Plus, some models have more complex systems with extra components. Maintaining and cleaning properly can prevent issues with a pilot light. 

My neighbor once shared a story with me.  They had ignored a flickering pilot light in their furnace for weeks before it went out in the winter cold. They had to spend a lot of money to fix their furnace and call an emergency heating service during one of their busiest days which could all have been avoided if they had paid attention to minor faults. 

Always monitor the performance of your gas-powered appliances. Knowing how a pilot light works isn’t rocket science – but it does involve a flame and some gas.

How a Pilot Light Works in A Furnace?

A pilot light is an important part of gas-powered appliances. It consists of a small gas burner, called a thermocouple or flame sensor, and a control valve. 

  • When you turn on an appliance, like a gas furnace or water heater, the pilot light will light up automatically.
  • The thermocouple detects the heat from the pilot light and sends an electric signal to the control valve. 
  • This opens to releasing gas into the burner assembly. This gas mixes with air and produces a steady flame. 
  • This flame heats up a metal rod in the thermocouple. 
  • This generates an electric current that keeps the control valve open and allows for continuous fuel flow.

Pilot lights are made to stay lit at all times. This can be helpful and risky. A constantly burning flame ensures quick ignition and reliable operation. But, it also poses a fire hazard if not properly maintained. 

Dust buildup or faulty parts can cause pilot lights to flicker or go out. This increases the risk of gas leaks and explosions. Regular inspection and cleaning of gas equipment by licensed technicians is recommended. 

Keeping your surroundings clean and well-ventilated, avoiding storing flammable items near gas appliances, and replacing outdated equipment with newer models are ways to help prevent these dangers. 

Newer models feature electronic ignition instead of traditional pilot lights. This eliminates potential sources of ignition while improving energy efficiency and performance. 

Even the smallest breeze can blow out a pilot light, just like a sneeze can ruin a first date.

Factors Affecting The Pilot Light Of Your Furnace

To troubleshoot issues with your furnace’s pilot light, you must consider various factors affecting its efficiency. I found that there are four different sub-sections you’ll need to examine to address your Pilot Light problems. These include insufficient gas supply, dirty or blocked components, drafts or wind, and malfunctioning thermocouples. By checking for these potential issues, you’ll be able to determine the proper solution and keep your furnace running smoothly.

Insufficient Gas Supply Can Affect Your Furnace

Pilot lights are essential for gas-powered appliances.  Gas lines may become clogged or depleted, meaning no natural gas reaches the pilot light and it goes out. Follow maintenance procedures to ensure your appliance has a consistent gas supply.

Furthermore, seasonal changes in demand can affect the natural gas supply in some areas. During periods of peak demand, there might not be enough natural gas for all devices. This doesn’t necessarily lead to the pilot light going out. Still, it is something to keep in mind.

For example, a family in rural Iowa decided to go off-grid and use propane for heating and cooking. But, they didn’t consider the increase in propane consumption during winter. Consequently, their pilot lights and heating system go out. This shows that an inadequate gas supply can be a problem, even with seemingly plentiful fuel sources.

Ensure that your appliances have a steady gas supply, be it natural gas or propane. Keep up with maintenance, and stay conscious of any issues that could disrupt the pilot light’s ability to ignite. 

Don’t let your pilot light get blocked – stay on top of it!

Dirty or Blocked Components that Can Affect Your Furnace

When it comes to pilot lights, dirt, and blocked parts can have a major effect on their performance. This can happen for several reasons. 

  1. For example, dirty burners can block the flow of gas, making the pilot light go out.
  2. Blockages in the gas line can also stop enough gas from reaching the pilot light. 
  3. Additionally, dirt and grime on the thermocouple can make it not get enough heat to stay lit. 
  4. Blockages in the air intake or exhaust flue can disrupt airflow, which could put out the pilot light. 
  5. Lastly, if the furnace filter is clogged, it can stop the proper airflow, resulting in overheating that shuts off the pilot light.

Therefore, it is important to keep these components clean and maintained. Not doing so could lead to inefficient fuel use and higher bills. Also, drafts or wind can blow out a pilot light quickly. 

HomeServe USA HVAC professionals state that 25% of furnace failure cases are due to dirt buildup on the pilots and burners.

Drafts or Wind that Can Affect Your Furnace Performance

The pilot light is a key part of gas appliances. It gives a continuous flame that lights up the gas when needed. But wind and drafts can put out the pilot light, affecting appliance use.

To avoid this, make sure all windows and doors are closed while using it. Also, you can put draft guards on windows and doors to reduce airflow. Sometimes even these steps won’t be enough. Then, think about getting a pilot light safety guard. This device can protect the flame from wind and keep it lit in bad weather.

Not paying attention to drafts and wind can lead to more energy being used up – and frequent relighting of the pilot light. Taking action can help your home appliances work properly – and save energy too! 

Take steps now to prevent power outages due to drafty windows and doors! And if your thermocouple isn’t working correctly – just remember: it’s not you, it’s them.

Malfunctioning Thermocouple of Furnace

A malfunctioning thermocouple can be the source of pilot light issues. This is a critical safety feature to prevent gas leaks and fires.

6 steps to troubleshoot and resolve:

  1. Find the thermocouple on your furnace or water heater.
  2. Clean the pilot light and thermocouple with compressed air.
  3. Detach the old thermocouple with a wrench or pliers.
  4. Replace it with the same length and specs.
  5. Screw in by hand, then secure with pliers. Don’t over-tighten.
  6. Relight the pilot light. Hold the reset button down for 30 secs, and release it after seeing the light stay lit.

Additional issues may exist, like dirty burners, low gas pressure, or failing controls. These need to be ruled out before replacing the thermocouple.

Steps to Restart Pilot Light In Your Furnace

To restart the pilot light on your furnace or water heater, you need to follow a few simple steps. In order to restore the heat to your home or apartment, you need to turn off the gas valve, remove the access panel, locate the pilot light, light the pilot light, and hold the reset button. This blog post will guide you through each of these sub-sections to ensure that you can safely and easily restart your pilot light on your own without having to call a professional.

Turn off the Gas Valve of the Furnace

Need to restart your pilot light? First, turn off the gas valve. This is essential for safety when dealing with gas appliances. Here’s how:

Also, make sure the furnace is installed in a well-ventilated spot. Clear any objects that might be obstructing its operation. By following these tips, you can save money on repairs and have an efficient home heating system. 

To keep Santa safe, install a cap on your chimney!

Installing a Chimney Cap

A chimney cap is a must-have to stop debris, leaves, and critters from entering your flue. Here’s a five-step guide on how to install it:

  1. Measure the dimensions of your flue to know the proper size for the cap.
  2. Select a tough material like stainless steel or copper.
  3. Attach anchor bolts to the flue to hold the cap in place.
  4. Securely attach the cap to the anchor bolts.
  5. Seal the edges with silicone caulk to stop any debris or animals from getting in.

While installing a chimney cap, don’t forget the details. Make sure it fits snugly and there are no openings for anything to get inside.

Don’t take chances! Protect your home and family by installing a chimney cap – you won’t regret it! Keep your firebox covered better than your ex’s restraining order.

Covering the Firebox

Covering the firebox is a key fire safety measure. Here’s a 4-Step Guide that can help:

  1. Get rid of dirt and debris from the area around the firebox.
  2. Place non-combustible materials around the opening.
  3. Cover the area with sheet metal or tiles.
  4. Seal the opening with heat-resistant caulk.

To stay safe, keep combustible materials away from the firebox. You can also use stainless steel chimney liners as an extra layer of protection. Additionally, make sure your house has working smoke detectors in each room and on every level. 

The NFPA states that 3 out of 5 home-fire fatalities result from faulty detectors. Check for drafts and downdrafts to ensure your house is safe.

Checking for Drafts or Downdrafts

Check for weak spots in insulation to prevent drafts and downdrafts. Hold a lit candle or incense near windows, doors, and other spots where air might leak in. If the flame flickers or the smoke blows away, seal the gap with caulk or weatherstripping.

Storm windows and doors act as a barrier between the inside and outside, reducing cold air entering. Cover windows with plastic in colder months to trap heat and reduce cold air seeping through small cracks.

By regularly checking for drafts and taking these prevention steps, you’ll keep warm air in and reduce energy costs. 

Don’t try to fix things yourself if it makes things worse – call a professional!

When to Call a Professional

To determine whether you need to call a professional for gas furnace repairs, look out for certain signs in your heating system. Gas leaks, malfunctioning gas control valves, and burner or igniter issues are the three sub-sections to explore in this section. If you experience any of these problems, it’s best to contact a professional for a solution.

Gas Leaks

Gas is a part of everyday life, but it can be dangerous if there’s a leak. Call a professional right away if you suspect one. Warning signs include a gas smell, hissing, or appliances not working properly. Don’t try to fix it yourself – it could make things worse.

A trained technician knows how to find and fix the leak safely. They’ll check the severity and decide what to do. It could be turning off appliances or valves connected to the gas. Shut off all gas-using appliances and pipes. Then, turn on all valves one by one, and look for smells or hissing.

If there is a leak or you think there might be, leave the area quickly and don’t turn on any lights or create sparks. Get help from outside the area.

Regular maintenance is the best way to avoid an emergency. If you have a faulty gas control valve, call a pro – unless you want to be a firework.

Malfunctioning Gas Control Valve of the Furnace

Gas control valve malfunction can be deadly. If you see signs of gas leakage or inadequate heating, get help right away! Maintenance is critical for safe operation. Neglect can lead to costly repairs or harm lives. 

The National Fire Protection Association says gas leaks caused 9% of home fires and 18% of fire deaths from home fires (NFPA). Don’t risk it with gas appliances always call in a pro if something looks off.

When your burner is more stubborn than a teen and your igniter is more unpredictable than the weather report, it’s time to consult an expert.

Burner or Igniter Issues of the Furnace

It’s annoying and risky when your burner or igniter isn’t working properly. Immediately call a specialist to prevent extra troubles. They’ll identify the matter – be it a broken part or a gas leak – and repair or switch it securely.

Never try to mend it by yourself as it may bring about costly harm and even put you and others in danger. 

Don’t postpone till your system totally stops functioning, get help from an expert the instant you detect any troubles with your burner or igniter.  Investing in your safety and peace of mind is worth it.

Remember the old saying: ‘Just because you can, doesn’t mean you should.’ Don’t attempt to DIY!


Wind can sometimes be the cause of a pilot light extinguishing on gas furnaces, water heaters, or other appliances. But, it’s also important to consider other possible causes, such as dirty thermocouples and gas leaks. To prevent issues from happening, regularly clean and maintain the components and ventilation system. If the wind is suspected, look for proper exterior venting and install a chimney cap.  According to Bob Vila’s website, dirty burners can lead to furnace sealant completely shutting down, causing costly damage in the long run. In conclusion, address pilot light problems by carefully inspecting and troubleshooting multiple components. Regular maintenance and cleaning can prevent major issues.
