If your pilot light keeps going out, it’s not just annoying – it could be a sign that something’s wrong with your gas fireplace. And whether the issue is large or small, a pilot light that won’t stay lit will stop the whole system from working.
So, what’s going on? There are several things that could be to blame – from something as simple as dirt build-up to more serious issues like faulty components. With the right guidance and repairs, though, you can address the problem and get back to relaxing in front of the fireplace in no time.
Common Reasons Your Gas Fireplace Pilot Light May Go Out
Gas Supply Issues
If you’ve had an interruption in gas service for any reason, your pilot light won’t stay going. Checking other gas appliances in your home can help identify if there’s a larger supply issue or if it’s specific to your fireplace.
A temporary drop in pressure can occur regionally for maintenance, but if you suspect a leak make sure you call your gas company immediately. This isn’t a problem to mess around with, since it can have very serious safety implications.
Dirty or Obstructed Pilot Light Assembly
This one is a common culprit. You can’t see it, but there’s a steady stream of gas fueling your pilot light. If something blocks or otherwise hinders that stream, it can’t do its job. Dirt, dust, or soot that builds up in the pilot assembly is enough to cause problems by clogging up the pilot tube or orifice. When your pilot light isn’t getting sufficient fuel and oxygen, it will weaken and go out easily – or won’t even light at all.
If you notice that your pilot flame is flickering or weak before it goes out, that might indicate that the pilot assembly is struggling to get the right balance or enough supply of air and fuel.
Spiders
Yeah, we know that spiders are notorious bad guys in most stories. Their notoriety might be a bit overblown, but these little insects actually can have a big impact on the functionality of your fireplace. Why, you may wonder? They’re drawn to the environment gas and propane fueled appliances can provide. Once there, they often build webs around the small ports and openings in the pilot assembly, which can block airflow and affect combustion. This in turn can also create sooting, which reduces efficiency.
Worn, Corroded, or Misaligned Components
Over time, the pilot light tube or other parts can become damaged or worn. If this is the case, they won’t deliver gas efficiently until cleaned or replaced. Another small, but important, part of your appliance is the thermocouple. This component senses the pilot temperature and causes the gas valve to close if it doesn’t detect a flame. If it’s damaged or misaligned it may send the wrong signal, shutting off the gas supply unnecessarily.
Airflow Issues
Think about the environment within your home. Is your pilot light exposed to drafts? It does need oxygen to function, but strong drafts or winds can blow it out. Conversely, blocked air can have a stifling effect. Consider the airflow dynamics surrounding your pilot light and whether you can adjust them to provide steady, consistent airflow.
Troubleshooting Pilot Light Issues
Just from reading through the list above, you may have some suspicions as to what’s causing your pilot light to go out.
Remember that before you investigate further, you should shut off the gas supply to your appliance. Also, read and follow your manufacturer instructions for maintenance and safety guidelines.
Then…
- Visually inspect your pilot light and the surrounding area for dirt, soot, webs, and other physical obstructions.
- Carefully clean the early with compressed air or a soft cloth or brush.
- Be sure to use a gentle touch and don’t use any flammable cleaners.
- Follow the manufacturer’s instructions to relight the pilot light.
- If it stays on a while then suddenly goes out, the thermocouple may be at fault.
- You can use a multimeter or call in a professional to check that it’s generating the correct voltage. If it isn’t, it may need to be replaced.
If after troubleshooting your pilot light still won’t stay lit (or if you aren’t comfortable with handling the appliance), a professional technician will be able to help. An experienced professional can safely inspect your appliance, identify the root cause of the issue, and repair or replace the necessary components.
