💡 10 Steps to Fix a Persistent Pilot Light Problem

Experiencing issues with your furnace pilot light can be incredibly inconvenient, especially during the colder months. This section offers a comprehensive, step-by-step guide to troubleshoot and fix a persistent pilot light problem, ensuring your home stays warm and cozy. Follow these 10 easy steps to get your furnace back in working order.

1. Check for a Draft

One of the simplest and most common reasons for a pilot light going out is a draft. A strong gust of wind or a persistent draft can blow out the flame.

What to do:

  • Inspect the area around the appliance for any drafts. Check windows, doors, and vents that may be allowing air to enter.
  • If you find any drafts, try to seal them off. This could involve closing doors, adding weather stripping to windows, or using draft stoppers.
  • If the pilot light is located in a basement or other area prone to drafts, consider installing a draft shield around the pilot light.
2. Clean the Pilot Orifice

The pilot orifice can become clogged with dirt, dust, or debris over time, which can impede the gas flow to the pilot light and cause it to go out.

What to do:

  • Turn off the gas and the appliance before attempting any cleaning.
  • Locate the pilot orifice. This is a small hole where the gas comes out to feed the pilot light.
  • Use a thin wire or a needle to gently clear any debris from the orifice.
  • You can also use compressed air to blow out any dirt or dust.
3. Inspect the Thermocouple

The thermocouple is a safety device that senses if the pilot light is lit and signals the gas valve to stay open. If it’s malfunctioning, it can shut off the gas supply, causing the pilot light to go out.

What to do:

  • Inspect the thermocouple to ensure it’s properly positioned in the pilot flame. It should be directly in the flame.
  • If the thermocouple looks dirty, clean it gently with steel wool or sandpaper.
  • Check the connections to ensure they are tight and secure.
  • If the thermocouple appears damaged or worn out, it may need to be replaced.
4. Check the Gas Pressure

Incorrect gas pressure can affect the pilot light’s ability to stay lit. Too high or too low pressure can cause the flame to go out.

What to do:

  • If you suspect a gas pressure issue, it’s best to contact a professional. They can check the gas pressure and adjust it if necessary.
  • Ensure that the gas valve is fully open.
  • If you have multiple gas appliances running, try turning off some of them to see if that affects the pilot light.
5. Examine the Gas Valve

The gas valve controls the flow of gas to the pilot light and burner. If it’s faulty, it can cut off the gas supply to the pilot light.

What to do:

  • Ensure the gas valve is in the correct position. It should be fully open.
  • Inspect the gas valve for any signs of wear, damage, or corrosion.
  • If you suspect the gas valve is malfunctioning, it’s best to have a professional replace it.
6. Test for a Faulty Thermostat

In appliances like furnaces, the thermostat controls when the gas valve opens and closes. A faulty thermostat can lead to the pilot light going out.

What to do:

  • Check the thermostat settings to ensure they are correct.
  • Replace the batteries in the thermostat if it’s battery-operated.
  • If the thermostat is old or malfunctioning, consider replacing it.
7. Look for Blockages in the Flue

The flue allows exhaust gases to escape from your appliance. If it’s blocked, the buildup of gases can extinguish the pilot light.

What to do:

  • Inspect the flue for any blockages, such as debris, bird nests, or soot buildup.
  • Clear any obstructions you find.
  • If the flue is damaged or needs cleaning beyond your ability, contact a professional for assistance.
8. Check for Ventilation Issues

Proper ventilation is crucial for gas appliances to function correctly. Poor ventilation can cause the pilot light to go out due to a lack of oxygen.

What to do:

  • Ensure there is adequate ventilation around the appliance.
  • If the appliance is in a confined space, consider installing a vent to allow fresh air to enter.
  • Make sure vents and air intake grilles are not blocked.
9. Ensure Regular Maintenance

Regular maintenance can prevent many of the issues that cause pilot lights to go out. Scheduled inspections and cleanings can keep your appliances running smoothly.

What to do:

  • Schedule annual maintenance checks with a professional technician.
  • During these checks, the technician can clean components, inspect for wear and tear, and make necessary adjustments.
  • Regular maintenance can extend the life of your appliances and improve their efficiency.
10. Consult a Professional

If you’ve tried all the above steps and your pilot light still won’t stay lit, it’s time to call in a professional. There may be underlying issues that require expert attention.

What to do:

  • Contact a licensed technician or plumber who specializes in gas appliances.
  • Describe the problem in detail, including any steps you’ve already taken to fix it.
  • Follow the professional’s advice and recommendations.
