Fire pits are one of the most sought-after backyard accessories. They create the perfect after-dark ambiance while making your outdoor spaces look spectacular and feel warm. However, sometimes, the gas pit just won’t stay lit. In this short read, we’re going to discover why fire pits malfunction as well as some troubleshooting tips.

Why won’t my fire pit stay lit? The problems

You’re out of gas

gas issues in fire pit

Most fire pits are propane gas pits and work the same way as gas stoves do. If your pit won’t light up properly, chances are that you’ve run out of gas. Lower fuel levels can cause the flame to burn inconsistently.

Those of you who’ve had the pit for a while should be able to judge how much gas you have in the propane tank simply by lifting the tank.

You have debris

Another reason why the pit may not be firing up is that debris such as leaves, twigs, and small insects may be blocking up the burner. Having debris blocking the burner can cause disruptions when the flame is lit.

This is something that can be easily avoided. Spend time cleaning up the burner ports and removing debris when the pit is not in use. Also, check if the burner is clean before you fire it up, especially if you haven’t used it in a  long time.

You have supply line kinks

If there is a kink in the supply line, the burner will not light up properly. Chances are that your supply line is bent, which is why gas isn’t being supplied adequately.

Make sure the supply line is straightened out and has enough space to stretch out to the fire pit. Also, be sure to periodically replace the supply line.

Another reason the supply of gas could be interrupted is if there is air in the gas line. To remove the air, simply allow the gas to flow through the line for a short while, forcing the air out. 

However, be sure there are no open flames in the vicinity while you’re doing this. The last thing you want to do is start a fire.

You have a gas leak

Propane fire pits that are leaking can be dangerous. If left unattended, this could lead to explosions and property damage.

Check the fuel line and if the gas leak is from there, replace the line. However, if the leak is from the fire pit itself, turn it off immediately until it has been repaired.

Your control valve is bust

If none of these is the reason your firepit isn’t firing up properly, the reason is probably that the control valve has been damaged. The only way to deal with faulty valves is to replace them.

While it is easy to find replacement control valves for newer models, replacement parts for older fire pits are hard to come by. You may need to buy a new propane fire pit.

Troubleshooting tips

Here are some troubleshooting tips to help you fix the problem when your fire pit just won’t fire up.

  • Turn off the gas supply to the pit and disconnect the fuel line. Then, check to see if the tank has gas in it. If fuel levels are low, get the tank refilled.
  • While turning it back on, remember to turn on the valve at the tank end first and then turn on the valve at the pit. Your tank has a safety valve that will prevent gas from flowing to the pit if you don’t follow this.
  • Fire pits often have battery-operated ignitors. If the ignitor does not spark, you may need to change the battery to get the firepit working again.
  • The smell of gas and a whistling sound is indicative of a gas leak. Switch off the gas immediately and use a liquid to check the gas line for leaks. Once you have confirmed the leak, replace the line.
  • Use a leaf blower or a vacuum cleaner to keep your burner ports clean. 
  • Check your thermocouple to make sure it is functioning. The thermocouple signals the gas valve to stay open when the pilot lights are on. If this is malfunctioning, the gas valve could shut automatically and your fire pit will not fire up.

Regular maintenance is the key

While a propane gas fire pit may be the ideal addition to your outdoor entertainment area, you will need to stick to a regular maintenance schedule if you want to enjoy it for a long time. However, if it should stop working out of the blue, the tips above ought to help you get it fired up again.
