FURNACE PILOT LIGHT OUT
A furnace pilot light that has gone out is a common yet concerning issue for homeowners, especially during the chilly months in the South Bay area of Los Angeles. The pilot light is a small flame that ignites the gas burner in your furnace. When it goes out, your heating system cannot function, leaving your home cold and uncomfortable. This problem can manifest suddenly, often without warning, and can be particularly alarming for families who rely on their heating systems for warmth. Understanding the causes and solutions can help you address the issue quickly, ensuring the comfort and safety of your household.
If you smell gas when attempting to relight, stop and call your gas company. Do not use matches or lighters if gas smell is present.

Symptoms
- 1No heat from furnace
- 2Pilot light won't ignite
- 3Pilot lights but goes out
- 4Clicking but no ignition
Common Causes
- 1. Drafts: Strong drafts can extinguish the pilot light. Open windows, doors, or gaps in insulation can create airflow that disrupts the flame.
- 2. Clogged Pilot Orifice: Dust and debris can block the pilot orifice, preventing gas from flowing properly and leading to an extinguished flame.
- 3. Thermocouple Failure: The thermocouple, a safety device that detects the pilot light's flame, may fail, leading to an automatic shut-off of gas flow.
- 4. Gas Supply Issues: If there are interruptions in the gas supply or low gas pressure, the pilot light may go out.
- 5. Faulty Gas Valve: A malfunctioning gas valve can prevent gas from reaching the pilot light, causing it to extinguish.
- 6. High Winds: For outdoor vented furnaces, high winds can blow out the pilot light, especially if the vent is not properly shielded.
- 7. Age and Wear: Older furnaces may have components that wear out over time, increasing the likelihood of pilot light issues.
BEFORE YOU CALL: DIY CHECKS
1. Check for Drafts: Inspect the area around the furnace for any drafts or open windows that might be affecting the pilot light.
2. Examine the Pilot Light: Look at the pilot light to see if it's completely out or just flickering. If it's out, proceed to the next steps.
3. Clean the Pilot Orifice: If you feel comfortable, gently clean the pilot orifice with a soft brush to remove any debris.
4. Inspect the Thermocouple: Ensure the thermocouple is properly positioned and not damaged. If it's loose or faulty, it may need replacement.
5. Verify Gas Supply: Make sure the gas supply to the furnace is turned on. Check other gas appliances to see if they are working.
6. Observe Weather Conditions: Consider whether recent high winds or severe weather could have affected the pilot light.
Homeowners can safely perform initial diagnostic steps such as checking for drafts, inspecting the pilot light, and verifying that the gas supply is on. Cleaning the pilot orifice may also be feasible for those comfortable with basic maintenance tasks. However, if the issue persists after these checks, or if you are unsure about handling components like the thermocouple or gas valve, it’s crucial to call a professional. Gas-related issues can be hazardous, and a qualified technician can ensure that repairs are done safely and effectively.
PREVENTION TIPS
WHEN TO CALL A PROFESSIONAL
If your pilot light goes out repeatedly or if you notice any unusual smells, such as gas, it is vital to call a professional HVAC technician immediately. Additionally, if you are uncomfortable performing any checks or repairs yourself, do not hesitate to seek professional help. Safety should always be the top priority when dealing with gas appliances.
