What Should I Do If My Pilot Light Keeps Going Out?

January 31, 2025

Does your furnace keep shutting off unexpectedly? If so, it may be an ignition issue.

When your pilot light keeps going out, it can leave you feeling frustrated and cold during chilly San Diego nights. This common heating issue often signals underlying problems that need professional attention. 

Understanding Your Furnace’s Pilot Light System

Your furnace’s pilot light plays a crucial role in heating your home. When functioning correctly, it ignites the main burner to produce warm air. A properly working indicator flame shows a steady blue flame about two inches tall.

Common Causes of Pilot Light Problems

Several factors can cause your gas flame to extinguish repeatedly. Understanding these issues helps you determine when to call a professional.

A faulty thermocouple often causes burner failures. This safety device monitors the flame and stops gas flow if it detects problems. When the thermocouple wears out or becomes covered in dirt, it may shut off the gas unnecessarily.

A malfunctioning flame sensor can also trigger shutdowns. This component ensures safe operation by verifying the flame’s presence. When it gets dirty or damaged, it may falsely signal that no flame exists.

Environmental Factors That Affect Your Pilot Light

Your furnace’s environment may be why your pilot light keeps going out. A strong draft near your furnace can blow out the flame. Check for air leaks around windows, doors, or ductwork that might create unwanted airflow.

A blockage in the gas line or venting system restricts proper fuel delivery, preventing the torch from receiving enough fuel to stay lit. Regular maintenance keeps excessive debris from building up in these crucial areas.

Safety Considerations for Pilot Light Issues

Your furnace includes a safety switch that cuts off gas flow when problems occur. While this may seem inconvenient, it protects your home from potential gas leaks. Never attempt to override these important safety features.

If you smell gas or notice unusual sounds when your indicator flame goes out, leave your home immediately and contact emergency services. These signs could indicate serious safety concerns that require immediate professional attention.

Your Next Steps When the Pilot Light Fails

When your torch keeps going out, first ensure the gas valve is fully open. Check for obvious drafts or debris around the furnace. If these simple fixes don’t work, don’t continue relighting the flame repeatedly.

Gas-powered appliances require specialized knowledge and training to repair safely. Working with an experienced HVAC professional ensures the problem gets fixed correctly while protecting your family from gas-related hazards.
