If the problem persists, our expert technicians are just a call away, ready to get your fireplace back up and running.
Types of Gas Fireplaces
Before we dive into troubleshooting, it’s important to understand what type of gas fireplace you have. This knowledge will make it easier to figure out what might be going wrong. Here are the two main types of gas fireplaces:
- Standing Pilot Light Fireplace: In fireplaces with a standing pilot light, the flame is always burning. While this uses a small amount of gas continuously, the upside is that it doesn’t rely on electricity. This means it will work even during a power outage.
- Electronic Ignition Fireplace: Many newer gas fireplaces have an electronic ignition system. Instead of a pilot light burning continuously, the fireplace ignites when you switch it on using electricity. Some models have battery backup systems to ensure they work during power outages, but you should always check the batteries in your backup system if you have one.
Now that you know what type of gas fireplace you’re dealing with, let’s look at common issues that might be preventing it from turning on.
Common Reasons Why Your Gas Fireplace Won’t Turn On
Gas fireplaces are relatively simple systems, and there are a few common reasons why they may stop working. Many of these problems are easy to fix on your own, but if you ever feel unsure or unsafe, it’s always best to call a professional. Safety is the number one priority when dealing with gas appliances.
Here are some of the most common issues that could be stopping your gas fireplace from turning on:
1. Pilot Light is Out
If your fireplace has a standing pilot light, the first thing to check is whether the pilot light is still lit. A gust of wind, debris, or other factors can cause the pilot light to go out. If the pilot light is off, follow the steps in our
guide to relighting a gas fireplace pilot light to get it going again.
For fireplaces with electronic ignition, you should check whether power is getting to the ignition system. Sometimes, the issue could be as simple as a blown fuse or a tripped circuit breaker. Replace any blown fuses with the same type and voltage or reset the circuit breaker and see if that fixes the problem.
2. Gas Valve Is Off
It might seem obvious, but one of the most common reasons a gas fireplace won’t turn on is that the gas valve is closed. Many people turn off the gas supply to their fireplace at the end of winter and forget to turn it back on when the next cold season arrives. Make sure the gas valve is in the
“On” position to ensure a steady flow of gas to the fireplace.
3. Thermocouple is Dirty or Misaligned
The thermocouple is a safety device found in fireplaces with a standing pilot light. It senses whether the pilot light is on and signals the gas valve to open or close. If the thermocouple is dirty or out of position, it may not detect the flame, and the gas won’t flow to the burner.
To fix this, you can gently clean the thermocouple with a soft cloth and make sure it’s correctly positioned near the pilot flame. If the thermocouple is worn out or damaged, you may need a professional to replace it.
4. Worn-Out Thermopile
Similar to a thermocouple, the thermopile is found in fireplaces with electronic ignition. This component converts heat from the pilot flame into electrical energy to ignite the burner. If the thermopile is worn out or misaligned, your fireplace won’t start. Replacing a thermopile can be more complicated, so if you suspect this is the issue, it’s best to call a professional technician from CANRO Heating & Cooling.
5. Battery Problems
If your gas fireplace uses a remote control, the issue might be as simple as dead batteries. Check both the remote control and the internal receiver to make sure the batteries are fresh. Replacing old batteries can solve the problem instantly in some cases.
6. Clogged Venting or Chimney
Gas fireplaces require proper ventilation to function efficiently. If your fireplace isn’t turning on, it could be due to a blockage in the venting or chimney, which is cutting off the oxygen supply. Check for any visible debris in the venting system or chimney and clear it out if possible. If you can’t access the blockage, it’s time to call in a professional.
Steps to Troubleshoot a Gas Fireplace That Won’t Turn On
Now that you know some of the common issues, here’s a step-by-step guide to troubleshooting your gas fireplace:
Step 1: Check for Gas Leaks
Before doing anything else, always ensure that there’s no gas leak. If you smell gas or suspect a leak,
immediately turn off the gas valve and call FortisBC or a certified gas technician. Never attempt to fix a gas leak on your own.
Step 2: Check the Pilot Light
If your fireplace has a standing pilot light, remove the cover and see if the pilot is lit. If it’s out, follow our guide to relighting the pilot light.
Step 3: Check the Gas Valve
Ensure that the gas valve is open and allowing gas to flow to your fireplace. Turn the valve to the
“On” position if it was closed.
Step 4: Inspect the Thermocouple or Thermopile
If the pilot light still won’t stay lit, inspect the thermocouple or thermopile for dirt or misalignment. Clean and reposition these components as necessary.
Step 5: Check the Batteries
If your fireplace has a remote control or battery-powered ignition system, check and replace the batteries in both the remote and internal receiver.
Step 6: Inspect the Venting and Chimney
Make sure there is no debris blocking the venting or chimney. Clear any obstructions to restore proper airflow to the fireplace.
If none of these troubleshooting steps solve the problem, it’s time to call a professional.
