Why Won't Your Pilot Light Stay Lit?: 1 Minute to Understand Common Issues and SolutionsSarah ThompsonSep 06, 2025Table of ContentsTips 1:FAQTable of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeIf your pilot light won't stay lit, it’s more than just a frustrating inconvenience—it can signal underlying issues with your heating appliance, whether it’s a furnace, water heater, or fireplace. The problem usually boils down to three main factors: a faulty thermocouple, a dirty pilot orifice, or gas supply complications.The thermocouple is a safety device that senses when the pilot light is on. If it’s malfunctioning, it won’t sense the flame, causing the gas valve to shut off. Over time, thermocouples can get dirty or wear out, so replacing or cleaning it often solves the problem. A clogged pilot orifice—where dust or soot blocks the small opening—can also prevent a steady flame, leading to repeated outages. Regular maintenance can prevent this issue.Gas supply interruptions—whether due to closed valves, leaks, or flow issues—are another common culprit. Ensure the gas supply is consistent and that all valves are open. If you suspect a gas leak, contact professionals immediately for safety. As a designer, I always recommend integrating accessible utility panels and easy-to-service components into room layouts for HVAC or water heaters. This ensures that routine checks, cleaning, and part replacements are simple and non-disruptive to your living space.Tips 1:Regularly schedule inspections and cleanings even if your pilot light is working.
