Gas Fire Pit Table Won’t Light? 7 Real Causes Homeowners Miss

A gas fire pit table that won’t light is frustrating, especially when everything looks like it should be working. In most cases, the issue isn’t serious — it’s usually something small like gas flow, ignition, or buildup that’s easy to overlook.

In this guide, we’ll walk through the real reasons a gas fire pit table won’t light, including both propane and natural gas setups used in many backyard fire tables from Outdoor Fire & Patio.

1. No Gas Flow or Low Gas Pressure

One of the most common issues is simply poor gas flow. If the tank is low, not fully opened, or the regulator has kicked in a safety shutoff mode, the fire table may not light at all.

With a propane gas fire pit table, this often happens when the tank valve is opened too quickly or the regulator senses a sudden surge and restricts flow.

👉 Quick check: Turn everything off, disconnect the tank for 1–2 minutes, then reconnect slowly and reopen the valve.

2. Ignition System Is Not Sparking

If you hear a clicking sound but nothing happens, the ignition system may not be sparking properly. Dirt, moisture, or a weak battery (on electronic igniters) can stop the spark completely.

This is one of the top reasons a fire pit ignition is not working, especially after rain or heavy outdoor use.

👉 Tip: Check the igniter button and replace batteries if your model uses them.

3. Burner Ports Are Blocked

Over time, dust, spider webs, or even small insects can block the burner holes on a gas fire pit table. When this happens, gas doesn’t flow evenly, and the flame may not light at all.

This is a common reason a fire table won’t ignite propane, especially when you smell gas but don’t see a flame.

In many fire pit systems, these small openings are sometimes referred to as “bullet burners”, and when they get clogged, ignition becomes difficult or completely fails.

👉 Tips:  A quick cleaning of the burner ports can often fix the issue.

4. Thermocouple Is Not Working Properly

The thermocouple is a small safety part that detects flame heat. If it’s worn out or misaligned, it can shut off gas flow even when you’re trying to light the fire.

A faulty thermocouple gas fire pit problem is more common in older fire tables or units exposed to heavy weather.

👉 Signs:

• Flame starts then goes out immediately
• Unit refuses to stay lit

5. Gas Regulator or Hose Issue

A damaged regulator or bent gas hose can restrict flow without being obvious. This often leads to a weak or no flame situation even when the tank is full.

Low pressure is a common low gas pressure fire pit issue that homeowners mistake for ignition failure.

👉 Check: Make sure the hose is straight and the regulator isn’t damaged or frozen.

6. Wrong Lighting Sequence

Sometimes the issue is simple user error. Many gas fire pit tables won’t light because the ignition button is pressed too quickly or the gas knob isn’t opened in the correct order.

Each model is slightly different, but most require gas to flow for a few seconds before ignition.

7. Safety Shutoff Has Triggered

Modern fire tables often include safety systems that shut off gas flow if something feels off. This can happen after multiple failed ignition attempts or sudden pressure changes.

If this happens, reset the system by turning everything off for a few minutes before trying again.

When to Stop Troubleshooting

If you smell gas strongly or the unit repeatedly fails to ignite, stop and let a professional inspect it. Gas systems are safe when working correctly, but they shouldn’t be forced.

Final Thoughts

Most cases where a gas fire pit table won’t light come down to airflow, ignition, or simple buildup — not major damage. A slow, step-by-step check usually solves the issue without needing repairs.

If you’re using premium fire tables or gas fire bowls from Outdoor Fire & Patio, regular cleaning and correct startup steps will prevent most of these problems from happening again.

FAQ

1. Why won’t my gas fire pit table light?

Usually due to no gas flow, weak ignition, or clogged burner ports.

2. Why does my fire pit table keep going out?

Most often from a bad thermocouple or unstable gas pressure.

3. What should I check first if my fire table won’t ignite propane?

Check gas supply, tank valve, and igniter function first.

4. Can low gas pressure stop ignition?

Yes, low pressure can prevent the burner from lighting properly.

5. Why is my fire pit ignition not working?

Moisture, dirt, or a weak spark are the most common causes.

6. Do propane and natural gas fire tables have the same issues?

Yes, both can face ignition and pressure-related problems.

7. When should I stop trying to light it?

Stop if you smell gas or it fails after multiple safe attempts.
