Before you learn how to fix your propane fire pit issues, you should know details about the problems. There are some common problems related to propane fire pits, and you should know about them to solve them. 

⮚ Clogged Fire Pit

When was the last occasion you cleaned your propane fire pit burner? Your fire pit will not ignite and stay lit if it has blockages with dirt and debris in the components. It may also get clogged by small parts of fire mediums like lava rocks and fire glasses. 

Even insects can get into the burner and clog it. Hence, it either blocks the fire or makes the flames inconsistent. When you turn off the fire pit, let it cool down properly. Then clean the burner. Your fire pit will burn steadily and produce sufficient heat. To prevent this problem from happening, cover your fire pit after use. 

⮚ Low Flame

Low flame in a propane gas fire pit can be because of a few reasons. The safety mechanism often limits the gas flow when it detects gas leaks and excessive gas flow. The regulator of the gas tank controls the gas to prevent any danger. As a result, your fire pit produces a low flame. 

The other reasons for low flame are: 

  • Your fire pit is leaking gas.
  • The supply pipe is partially inflated or has a snag.
  • Damage to the control valve.

Most of the time, you can solve the problem of low flame by yourself. But if you are not sure about your mechanical skills, seek professional help. 

⮚ Flickering

Is your propane fire pit flickering out even if there is now strong wind? Then the propane fire pit may have a few problems in different parts to stay lit. The shimmering can happen because of faulty valves or thermocouple connection problems.  

The gas line may also get air inside, which causes the fire to flicker from time to time. Your propane fire pit will ignite, but it will turn off or flicker. So, press and hold on to the control valve of the fire pit for 10 to 30 seconds. It enables the thermocouple to heat the pilot and keep it operating for a long time. 

But if you have a problem with the control valve and the thermocouple, the fire pit will not consistently perform.

When your fire pit is malfunctioning, do not get panicked. Most of the time, it is easy to fix propane fire DIY. Follow these simple steps to fix the problems we just discussed.  

Shut off the gas supply to the home or business; first of all, make sure to turn off the gas supply of the fire pit. No matter what problem you face, it is wise to detach the fire pit from the fuel source lines immediately. If you have a propane fire pit, close the valve of the propane tank

Then disconnect the fuel connection of the pit from the gas tank. If you have a natural gas-fueled fire pit, detach it from the gas line.

Fill up the Tank

You are not getting low fire from the pit because the fire tank is empty, not full enough. It is as simple as that. So, check the fuel in the propane tank. If it is low, refill or replace the tank. 

When you want to light your fire pit, first, turn on the valve of the tank. After that, open the fire pit valve. If you turn on the fire pit valve first, the safety valve of the tank may stop the gas supply. 

Activators and Ignitors

Your fire pit ignitor should spark to create fire. Most of the propane fire pits these days operate on batteries. To locate the batteries, you have to unscrew its button or open the compartment. 

Disconnect the existing battery and swap it with a new one, ensuring to conserve the precise polarity of the battery. Also, check the wire of the ignitor switch is connected to the ignitor. Cleaning the ignitor terminal will also help improve its performance. Using a ball of steel wool or bristle brush, gently clean the ignitor.

Is there gas in the Hose?

Do you smell gas in the house? Your indoor propane fire pit can be the cause of the propane smell. See if gas is leaking from it. Close the gas valve and remove flammable things from the spot. 

Next, check the propane supply line. Gas may come out from the cracks of the supply pipe. Apply gas leak checking liquid on valve, pipes and fittings to find out leaks. Turn on the gas valve half around slowly. If you see bubbles from the liquid applied part, the leak is there. 

You must replace the faulty parts and make sure to install new features safely. If the fittings have bubbles, tighten them well. Keep checking for leaks until you find all of them.  

Clean the Stoves and Ovens 

Your fire bit burner can get clogged. Hence, you get no or low fire. So, keep the fire pit stove or burner clean. Remove the lava rocks or fire glasses from the propane fire pit. Then brush off the dirt. 

You can use a vacuum cleaner for more effective results. Once the burner is clean, your fire pit should produce fire like it used to do. 


You may find everything is fine with the burners and gas tank, even though the fire pit is not igniting. The thermocouple of your fire pit may be at fault in this case. It monitors the heat from the pilot light, and when the pilot light flame is on, the thermocouple signals the gas valve to stay open. 

So, secure the thermocouple connections with the gas. The connection should not be too rigid or underly loose. Consult with an expert if you cannot fix the thermocouple. 

Producing a Whistling Noise

You may not have any issue with the fire. But now, it may make too much whooshing sound. It indicates there is an excess of gas flowing out of the burner. Bend the gas line to control excess gas. An unfitting regulator can also cause too much gas supply. Make sure the regulator is not too small for the fire pit. 

How Can I Get Parts For My Propane Fire Pit?

Now, you have troubleshot your propane fire pit and tried to fix it. If you are lucky, you may not have to change any parts of your fire pit. But sometimes, you cannot help replace some of the damaged parts of the fire pit. So, where do you get propane fire pit parts? 

Always check with the manufacturer of the fire pit for replacement parts. You can visit their stores or check their websites for parts of your propane fire pits. You can also choose any parts from any company that matches your fire pit. If you have a handmade fire pit, ask the constructor where you can get replacements.

In a typical case, the fire of the propane fire pit will stop burning when the propane tank gets empty. So, you have to replace the tank or refill it. In both cases, you must remove the propane tank from the fire pit and reconnect it after filling the gas. 

You can change the propane fire tank by yourself with no problem. Remove the propane tank safely from the fire pit. Before that, turn off the gas valve. Now, follow these steps: 

Step 1- Get/ Refill the Propane Tank.

Buy a new propane gas tank or refill the old empty one from an authorized dealer only. This is important for your safety; authorized dealers follow all safety protocols while filling an empty gas tank. You should completely seal off the gas valve of the new propane tank. Never use an open propane gas tank. 

Step 2- Check the Valve 

As I mentioned, the gas valve should be sealed, and you must securely turn it off. When you install the tank, remove the plastic seal or cap of the gas tank. 

Tighten all connections with a wrench, taking an incredibly close look at the thermocouple and gas valve.

Step 3- Connect with the Hose.

Your propane fire pit’s hose and its regulator should be clean. Also, make sure the hose pipe has no leaks. You need to attach a clean regulator to the propane tank. Connect the hose and the tank via the regulator. Use your hands to ensure, secure and tight connection.  

Bends inflexible lines, excessive gas supply, and insufficient sizing are the foremost reasons for inadequate burner output.

Step 4- Connecting to Your Fire Pit

If you use an internal propane fire tank, open the propane tank compartment under the fire pit. Then place it on the tank ring for a secure connection. Push the fire pit to check it shakes. It should not move. So, put it on the spot firmly. 

Step 5- Check the Connection 

You may want to make sure the propane tank is safely connected to the fire pit. For that, you need a liquid gas leak checker, or you can use homemade soap and water solution.

First, you need to turn on the gas valve of the propane tank. Then use a spray bottle to apply the liquid gas leak checker on the propane tank surface, tank regulator and hose valve. Wait for a while to allow the gas to flow through the hose. 

If you see bubbles are forming on these parts, it means there are leaks. So, turn the valve clockwise and secure it. Then check the other connections and secure them in place tightly. 

How Do You Clean & Maintain A Propane Fire Pit?
