Furnace Pilot Light Out? What Greater Vancouver Homeowners Should Know
A furnace pilot light that has gone out is one of the most common heating emergencies we encounter at BC Wide. While older furnaces with standing pilot lights are becoming less common, many homes in Greater Vancouver still use these systems, and newer electronic ignition systems can also fail in similar ways. When your pilot light is out, your furnace cannot produce heat, and the problem is often accompanied by a gas smell as the safety valve may not be fully sealing. Understanding the difference between a simple pilot outage and a more serious gas control valve issue can help you decide whether to relight it yourself or call a licensed professional. BC Wide serves all of Metro Vancouver with prompt and reliable furnace service.
How to Safely Relight a Standing Pilot Light
If you have an older furnace with a standing pilot light and know what you are doing, relighting it is a straightforward process. Start by locating the gas control valve on your furnace and turning it to the off position. Wait at least five minutes for any accumulated gas to dissipate before attempting to relight. Switch the valve to pilot setting, depress the reset button, and hold a long-reach lighter or BBQ igniter to the pilot opening. Keep the reset button depressed for about thirty seconds after the pilot ignites to allow the thermocouple to heat up. Release the button and turn the valve to the on position. If the pilot does not stay lit, the thermocouple may need replacement.
Common Causes of Pilot Light and Ignition Failures
Standing pilot lights can fail for several reasons, many of which point to larger mechanical issues. A faulty thermocouple is the most common culprit, as this safety device senses whether the pilot flame is present and will shut off gas flow if it does not detect heat. Drafts from open doors, windows, or ductwork can blow out a pilot flame, especially in older furnaces located in basements or utility rooms. A dirty pilot orifice can produce a weak yellow flame that fails to properly heat the thermocouple. In electronic ignition systems, failed ignitors, faulty flame sensors, and control board issues are more likely culprits. Each of these problems requires professional diagnosis and repair to restore reliable operation.
When to Skip DIY and Call a Licensed Gas Fitter
If the pilot light repeatedly goes out after you relight it, or if you smell gas at any point during the process, stop and call a licensed professional immediately. Attempting multiple relights without addressing the underlying cause can be dangerous, especially if the gas control valve is faulty. BC Wide's Red Seal certified technicians carry replacement thermocouples, gas valves, ignitors, and control boards in their vans for same-day repair. In Vancouver and surrounding areas, call (604) 330-3953 for prompt service. We serve all of Metro Vancouver including Burnaby, Coquitlam, Surrey, Richmond, Delta, Langley, and the North Shore.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
