Fireplace Pilot Light Stays On

Fireplace Pilot Light Stays On: Causes and Solutions

A fireplace pilot light is a small flame that burns continuously to ignite the main burner when needed. While it's common for the pilot light to remain lit, it can occasionally malfunction and stay on indefinitely. This can not only waste gas but also pose a safety hazard.

If your fireplace pilot light stays on, it's important to troubleshoot the problem and find a solution to ensure its proper functioning. Here are some common causes and their corresponding solutions:

1. Faulty Thermocouple

The thermocouple is a device that senses the temperature of the pilot flame and sends a signal to the gas valve to open or close. A faulty thermocouple can send an incorrect signal, causing the gas valve to remain open even when there's no demand for heat. To resolve this issue, replace the faulty thermocouple with a new one.

2. Dirty Pilot Light

Dirt and debris can accumulate on the pilot light, blocking the flow of gas and preventing the flame from burning properly. This can result in the pilot light staying on continuously. Clean the pilot light orifice and surrounding area using a soft brush or compressed air. Once cleaned, relight the pilot light.

3. Misaligned Pilot Light

If the pilot light is not properly aligned with the thermocouple, it may not be able to send a strong enough signal to the gas valve. This can cause the gas valve to stay open, resulting in a continuous pilot light flame. Realign the pilot light to ensure it's positioned directly in front of the thermocouple.

4. Faulty Gas Valve

The gas valve is responsible for controlling the flow of gas to the pilot light. A faulty gas valve can malfunction, causing it to remain open even when there's no need for heat. If you suspect a faulty gas valve, it's best to contact a qualified technician for repair or replacement.

5. Damaged Pilot Tube

The pilot tube is a small tube that supplies gas to the pilot light. If the tube is damaged or kinked, it can restrict the flow of gas and cause the pilot light to stay on continuously. Inspect the pilot tube for any damage and replace it if necessary.

If you're unable to troubleshoot and resolve the problem yourself, it's highly recommended to seek assistance from a licensed gas fitter or fireplace technician. They have the experience and expertise to safely diagnose and repair any issues with your fireplace pilot light.

Remember, a malfunctioning pilot light can pose a safety hazard. If you notice any unusual behavior or suspect a problem, do not attempt to repair it yourself. Contact a qualified professional for prompt and safe resolution.
