A gas fireplace adds a lot to a home – warmth, ambiance, convenient heat…the list could go on. But when the pilot light won’t ignite, it can leave you feeling frustrated – and cold.
If you’re dealing with this issue, you’re not alone. Several common reasons could be behind a malfunctioning pilot light, ranging from simple fixes to more serious concerns. If you’re having trouble with your gas fireplace, don’t wait to call us out. We’ll address the problem, so you can get back to enjoying a cozier fall and winter season.
7 Common Reasons Your Gas Fireplace Pilot Light Won’t Light
1. Lack of Gas Supply
Is your gas valve closed? If the valve is closed or partially open, gas won’t reach the pilot light.
Is the gas line obstructed? If other gas appliances in your home aren’t working, the issue might be with the gas supply line.
2. Faulty Thermocouple
The thermocouple is a safety device that detects if the pilot light is on. If it senses no heat, it shuts off the gas supply to prevent gas buildup. Over time, the thermocouple can wear out, get bent, or become covered in dirt, preventing it from detecting heat correctly.
3. Dirty Pilot Tube
If dust, soot, or debris is clogging the pilot tube (the small pipe that delivers gas to the pilot light), the flame either won’t ignite or it will be weak and unstable. Cleaning the pilot tube is usually necessary to restore proper gas flow to the flame.
4. Air in the Gas Line
Sometimes, air can become trapped in the gas line, particularly if the fireplace hasn’t been used for a while. This air can prevent gas from reaching the pilot light. To resolve this, the gas line needs to be bled, which can be done by a professional or by following the fireplace manual.
5. Low Gas Pressure
If your gas pressure is too low, the pilot light may not light at all or may go out frequently. This could indicate a problem with the gas provider or a regulator issue. You may need to contact your gas provider to check your home’s gas pressure or have a technician inspect the regulator.
6. Thermopile Malfunction
The thermopile is another safety component that works alongside the thermocouple. It converts the heat from the pilot light into electrical energy to keep the gas valve open. Like the thermocouple, the thermopile can wear out or fail due to dirt or mechanical issues, preventing the pilot light from staying on.
7. Worn Out Igniter
If your fireplace uses an electronic igniter, it may fail over time. The igniter creates the spark that lights the pilot flame. If it’s worn out or faulty, the spark may not be strong enough to ignite the gas.
Are DIY Gas Pilot Light Fixes Possible?
If your pilot light has gone out due to a draft or temporary gas interruption, it can usually be relit by following the manufacturer’s instructions. This typically involves turning off the gas, waiting a few minutes, and using a match or igniter to relight the pilot.
In addition, a weak or flickering flame may be due to dirt or debris blocking the pilot light. Cleaning the orifice and surrounding area can improve its performance.
If neither of those options worked, call in an expert. Fireplaces and gas lines aren’t something a homeowner should try and take care of themselves, and if even a small mistake or mishap occurs, much bigger – and more hazardous – problems could occur.
When it comes to your heating system, always prioritize safety and leave gas-related repairs to the professionals.
What Should I Do if I Suspect My Gas Fireplace Is Leaking?
Prompt action and professional intervention are key to handling gas leaks safely.
If you have time…
- Turn Off the Gas: Locate the gas valve near the fireplace and turn it off to stop the flow of gas.
- Ventilate the Area: Open windows and doors to let fresh air in and allow any gas buildup to dissipate.
- Avoid Using Electrical Devices: Don’t use any electrical switches, appliances, or even phones, as they can create sparks that might ignite the gas.
That said, these steps should always be your first priority:
- Evacuate the Area: Leave the house, especially if the smell of gas is strong, to avoid potential exposure to harmful fumes or the risk of an explosion.
- Call the Gas Company or Emergency Services: Once you are safely outside, contact your gas provider or emergency services. They can send a technician to inspect the leak and ensure everything is safe.
- Do Not Attempt DIY Fixes: Never try to repair a gas leak yourself. It’s crucial to leave this to licensed professionals to avoid serious hazards.
- Stay Outside Until You’re Given the All Clear: Until you know your home is free of any hazardous gases, don’t re-enter.
And once everything is taken care of…
- Call Us Out for an Inspection: Once the issue has been addressed, it’s important to schedule a professional fireplace inspection to ensure your gas fireplace is safe and functioning properly.
- Refrain From Using Your Gas Fireplace: Avoid using your gas fireplace until the chimney technician confirms it is safe to operate.
