Gas Fireplace Pilot Light Stays On

Essential Aspects of Gas Fireplace Pilot Light Stays On

A fireplace is a great way to add warmth and ambiance to your home. However, if the pilot light stays on, it can be a nuisance and a potential safety hazard. Here are some essential aspects of a gas fireplace pilot light that stays on and how to troubleshoot the issue.

What is a Pilot Light?

A pilot light is a small flame that burns continuously to ignite the main burner when you turn on your gas fireplace. It is usually located near the bottom of the fireplace and can be adjusted using a small knob or screw.

Why Does the Pilot Light Stay On?

There are several reasons why the pilot light on a gas fireplace may stay on, including:

Dirty or blocked pilot light orifice: The orifice is a small hole that allows gas to flow to the pilot light. If it becomes clogged with dust, dirt, or debris, the pilot light may not be able to stay lit.
Faulty thermocouple: The thermocouple is a safety device that shuts off the gas supply to the pilot light if it goes out. If the thermocouple is faulty, it may not be able to detect that the pilot light is out and will continue to allow gas to flow.
Debris or obstruction in the gas line: If there is debris or an obstruction in the gas line, it can prevent gas from reaching the pilot light, causing it to go out.
Incorrect gas pressure: The gas pressure to your fireplace must be within a specific range for the pilot light to function properly.

How to Troubleshoot a Gas Fireplace Pilot Light That Stays On

If your gas fireplace pilot light stays on, you can try the following troubleshooting steps:

Check the pilot light orifice: Look for any dirt, dust, or debris blocking the orifice. If you see any, gently clean it out with a soft brush or compressed air.
Test the thermocouple: Remove the thermocouple from the fireplace and hold it over a lit match or lighter. If the thermocouple is working properly, the pilot light should ignite within a few seconds.
Inspect the gas line: Check the gas line for any kinks or obstructions. If you find any, carefully remove them.
Adjust the gas pressure: If the gas pressure is too high or too low, it can cause the pilot light to stay on. Contact a qualified technician to adjust the gas pressure.

When to Call a Professional

If you have tried the troubleshooting steps above and the pilot light still stays on, it is best to call a qualified gas fireplace technician. They will be able to diagnose the problem and make the necessary repairs.
