Wind Keeps Blowing Out Pilot Light : Solutions And Prevention Tips

Wind Keeps Blowing Out Pilot Light

Key Take Away:

This guide addresses the common problem of pilot lights in gas appliances being extinguished by strong winds. Explaining the dual role of pilot lights in ignition and safety, it provides troubleshooting steps such as checking for leaks, installing wind guards, adjusting ventilation, and relocating appliances. Suggestions include regular maintenance, checking gas pressure, and upgrading to wind-resistant pilot lights. The importance of safety, FAQs, and seeking professional assistance for persistent issues are emphasized. The goal is to ensure reliable and safe appliance performance in all weather conditions.


A pilot light is a small, continuously burning flame that initiates the main burner in numerous gas-powered appliances like furnaces, water heaters, and gas stoves. It plays a pivotal role in ensuring the safe and efficient operation of these appliances. Nevertheless, a common issue encountered by many homeowners is that, strong wind keeps blowing out pilot light. In this comprehensive guide, we will explore the causes of this problem and present practical solutions to maintain a consistently burning pilot light, thus ensuring the reliable performance of your appliance.

Understanding The Pilot Light

Before delving into wind-related issues and their solutions, it is imperative to comprehend the functioning and significance of a pilot light. The pilot light serves two primary purposes:

  1. Ignition: The pilot light serves as an ignition source, igniting the main burner when the appliance’s thermostat or control system signals the need for heat. It provides a small, stable flame that is always ready to ignite the gas.
  2.  Safety: Additionally, the pilot light functions as a safety mechanism. If the pilot light goes out, it prevents the flow of gas into the appliance, thus averting the potential hazard of a gas leak.

Common Appliances With Pilot Lights

Several household appliances rely on pilot lights, including:

  1. Gas Furnaces: Pilot lights are commonly found in older gas furnaces, responsible for initiating the main burner to heat the home.
  2. Gas Water Heaters: In gas water heaters, the pilot light is responsible for heating the water within the tank.
  3. Gas Stoves and Ovens: Some older models of gas stoves and ovens employ pilot lights to ignite the burners or the oven.

Why Does Wind Affect Pilot Lights?

Pilot lights are relatively small flames that burn continuously. Due to their size, they are vulnerable to being extinguished by strong wind gusts. When the wind blows across the pilot light, it can disrupt the flame’s stability, leading to its extinguishment. This can be particularly frustrating for homeowners, especially during windy seasons or in regions prone to gusty weather.

Common Scenarios Where Wind Affects Pilot Lights:

  1. Outdoor Appliances: Outdoor gas appliances such as patio heaters and grills are especially susceptible to issues related to pilot lights being affected by the wind.
  2. Ventilation Systems: Pilot lights in appliances connected to ventilation systems, like furnaces, may experience problems if wind enters the venting system and disrupts the pilot.
  3. Leaky Seals and Cracks: In certain cases, wind can infiltrate the appliance housing through seals or cracks, directly affecting the pilot light.
  4. Chimney Draft: In homes equipped with fireplaces and gas logs, wind blowing down the chimney can impact the pilot light, especially when the damper is not correctly closed.

Pilot Light Keeps Blowing Out: Troubleshooting and Solutions

You can follow these troubleshooting steps and solutions to address the issue of the pilot light being blowing by the wind:

1. Check for Leaky Seals and Cracks:

Examine the appliance for any visible leaks, cracks, or openings that allow wind to reach the pilot light. If identified, seal them using appropriate materials, such as high-temperature silicone or gaskets.

2. Install Wind Guards:

For outdoor appliances like grills and patio heaters, consider installing wind guards or shields around the pilot light. These shields serve as a barrier against strong winds.

3. Adjust Ventilation:

If your appliance is connected to a ventilation system, ensure that the venting system is not directing wind directly onto the pilot light. Adjust the vent or install a baffle to redirect the wind away from the flame.

4. Install a Draft Hood:

In some instances, a draft hood on the vent pipe can mitigate the impact of wind on the pilot light. A draft hood establishes a buffer zone that reduces the wind’s effect on the pilot.

5. Chimney Cap:

When dealing with gas fireplaces, contemplate installing a chimney cap. This addition can prevent downdrafts and wind from entering the chimney and affecting the pilot.

6. Relocate Outdoor Appliances:

Whenever possible, relocate outdoor gas appliances to less exposed areas with reduced wind exposure. This step can decrease the likelihood of the pilot light extinguishing.

7. Regular Maintenance:

Ensure your appliance undergoes routine maintenance. Cleaning the pilot assembly, burner, and adjacent components can stabilize the flame.

8. Check Gas Pressure:

Low gas pressure can increase the vulnerability of the pilot flame to wind-induced extinguishment. Engage a qualified technician to assess gas pressure and make any necessary adjustments.

9. Use Wind-Resistant Pilot Lights:

Some modern appliances feature wind-resistant pilot lights designed to withstand adverse weather conditions. If wind-induced pilot light issues persist, contemplate upgrading to an appliance equipped with this feature.

10. Consult a Professional:

If you have exhausted the above steps and continue to face pilot light issues, it is advisable to consult a professional technician or plumber specializing in gas appliances. They can conduct a thorough inspection and propose a customized solution.

Frequently Asked Questions

Q: How can I prevent the wind from blowing out my pilot light?

A: You can utilize a wind guard or shield to safeguard the pilot light or consider relocating the appliance to an area less affected by strong winds.

Q: Is it safe to relight the pilot light after it’s been extinguished by the wind?

A: Yes, relighting the pilot light is safe, but always adhere to the manufacturer’s instructions and safety guidelines.

Q: Can I use a wind-resistant pilot light design?

A: Some newer appliances come equipped with wind-resistant pilot light designs, which can help mitigate this issue.


A pilot light prone to extinguishing due to wind can be a vexing problem, however, it can often be resolve with the appropriate troubleshooting and solutions. By comprehending the root causes of this issue and taking proactive measures to address them, you can ensure that your gas-powered appliances function reliably and safely, regardless of prevailing weather conditions. Always prioritize safety when dealing with gas appliances, and if you have any uncertainties regarding troubleshooting or maintenance, do not hesitate to seek professional assistance.
