Why Does My Pilot Light Keep Going Out?: 1 Minute to Identify and Fix Common Pilot Light Issues

If your pilot light keeps going out, it’s more than just a minor inconvenience—it’s a signal that something in your gas appliance needs attention. The pilot light is a small flame that ignites the burner in appliances like furnaces, water heaters, and gas fireplaces. When it won’t stay lit, the root causes might range from simple airflow issues to malfunctioning parts. Most commonly, a dirty or faulty thermocouple, drafty areas near the appliance, or an insufficient gas supply are to blame. Carbon buildup can prevent the thermocouple from sensing the flame, causing the gas supply to shut off as a safety measure. Alternatively, a damaged or aging thermocouple may not signal properly even when clean, requiring replacement. Sometimes, adjustments to the gas regulator, fixes to leaks, or sealing up drafts can restore normal operation.

As a designer, I always recommend that homeowners consider not just the function, but also the placement and design of appliances. For example, gas appliances placed near windows or high-traffic areas are more prone to drafts, which can blow out the pilot light. When planning or updating a space, integrating your appliances thoughtfully can prevent ongoing maintenance headaches. For those considering appliance upgrades or new layouts, exploring professional-grade kitchen layout planning tools is an excellent step in achieving both efficiency and a worry-free environment.

Tips 1:

Regularly check and clean the area around your pilot light to remove dust or debris that can affect performance.

FAQ

Q: What is the most common reason a pilot light won’t stay lit?

A: A dirty or malfunctioning thermocouple is usually the main culprit when a pilot light keeps going out.

Q: Can drafts really cause my pilot light to blow out?

A: Yes, drafts from windows, doors, or fans can disrupt the flame and cause the pilot to extinguish.

Q: Should I attempt to fix a faulty thermocouple myself?

A: While cleaning is simple, replacing a thermocouple is best left to a professional for safety reasons.

Q: How often should pilot lights be checked or maintained?

A: It’s good practice to inspect and clean the pilot light annually, or whenever you notice issues.

Q: Does appliance location affect pilot light reliability?

A: Absolutely. Appliances installed in drafty or heavily trafficked locations are more susceptible to pilot light problems.
