Pilot Light Lifesavers: Quick Fixes for Common Issues

The pilot light in your gas-powered appliances, such as furnaces, water heaters, and stoves, plays a crucial role in their operation. When the pilot light goes out or encounters problems, it can disrupt the functioning of these appliances. In this blog post, we’ll explore common pilot light issues and provide quick fixes to get them up and running again.

1. Pilot Light Won’t Stay Lit

Issue: The pilot light ignites but won’t stay lit.

Quick Fix: Check for a dirty or clogged pilot orifice. Turn off the gas supply, wait a few minutes for any lingering gas to dissipate, and then use a thin wire to gently clean the orifice opening. Relight the pilot.

2. Weak or Flickering Pilot Flame

Issue: The pilot flame is weak, flickering, or appears yellow.

Quick Fix: This could be a sign of insufficient gas flow or a dirty pilot tube. Turn off the gas supply, clean the pilot tube using compressed air or a fine wire, and ensure that the pilot flame envelops the thermocouple properly.

3. Pilot Light Keeps Going Out

Issue: The pilot light repeatedly goes out shortly after ignition.

Quick Fix: Check for drafts around the appliance. Seal any gaps or openings that may be allowing drafts to blow out the pilot flame. Ensure the appliance is placed in a well-ventilated area.

4. Pilot Light Doesn’t Ignite

Issue: The pilot light doesn’t ignite when you try to light it.

Quick Fix: Check if the gas supply is turned on. If it is, ensure that there’s no air in the gas line by holding the pilot knob down for a longer period before lighting it. If the problem persists, it could be a faulty thermocouple or gas valve that requires professional attention.

5. Thermocouple Failure

Issue: The pilot light goes out when you release the pilot control knob.

Quick Fix: This is often caused by a malfunctioning thermocouple. Try tightening the thermocouple nut slightly. If that doesn’t work, you may need to replace the thermocouple.

6. No Gas Smell

Issue: You don’t smell gas when attempting to relight the pilot.

Quick Fix: This can be a safety concern. If you don’t smell gas, it could indicate a gas supply issue. Check the Heating repair valve, gas line, and shut-off valve for any problems, and consult a professional if needed.

7. Excessive Soot or Carbon Buildup

Issue: You notice excessive soot or carbon buildup around the pilot light.

Quick Fix: This buildup can interfere with the pilot flame. Turn off the gas, let it dissipate, and then carefully clean the pilot assembly, burner, and surrounding area. Ensure proper ventilation to prevent future buildup.

8. Pilot Light Won’t Ignite After Long Disuse

Issue: After an extended period of disuse, the pilot light won’t ignite.

Quick Fix: It’s possible that the gas line may have air in it. Hold down the pilot control knob for an extended period (up to a minute) to purge the air from the line, and then try lighting the pilot again.

9. Check for Gas Leaks

Issue: You suspect a gas leak around the pilot light.

Quick Fix: Gas leaks are extremely dangerous. If you suspect a leak, do not attempt to relight the pilot or use the appliance. Turn off the gas supply immediately, ventilate the area, and contact a professional to inspect and repair the gas line.


Addressing common pilot light issues requires some basic troubleshooting skills and a cautious approach. While many issues can be resolved with quick fixes, it’s essential to prioritize safety and contact a professional when dealing with more complex or potentially hazardous problems, such as gas leaks or faulty thermocouples. By following these quick fixes and conducting regular maintenance, you can keep your gas-powered appliances running smoothly and safely.
