1. Check the Gas Supply

One of the first things you should check when your gas grill isn’t heating up properly is the gas supply. Ensure that the gas tank is properly connected and has enough fuel. Here are a few steps to follow:

  • Verify the gas tank: Check if the gas tank is empty by carefully weighing it. If it is empty, replace it with a full tank.
  • Check the connections: Inspect the gas connections between the tank and the grill. Make sure they are tightly secured and not damaged. If you detect any leaks or damage, replace the faulty parts.

2. Clean the Burner and Venturi Tubes:

A common cause of low heat output is a clogged burner or venturi tubes. Over time, these components can accumulate dirt, grease, and debris, restricting the flow of gas. Follow these steps to clean them:

  • Turn off the gas supply: Before cleaning, always turn off the gas supply and disconnect the propane tank.
  • Remove the burner: Detach the burner by removing the screws or fasteners holding it in place. Take note of its position for reassembly.
  • Clean the burner: Use a wire brush or a grill brush to remove any residue, rust, or debris from the burner surface. Pay attention to the burner ports, ensuring they are clear and unobstructed.
  • Clean the venturi tubes: The venturi tubes connect the burner to the control valves. Remove them carefully and clean any obstructions with a pipe cleaner or small brush.
  • Reassemble the components: Once everything is clean and dry, reassemble the burner and venturi tubes in reverse order. Ensure they are properly aligned and securely attached.

3. Check the Regulator and Hose:

A malfunctioning regulator or hose can significantly impact the heat output of your gas grill. Here’s what you can do to address this issue:

  • Inspect the regulator and hose: Check for any visible signs of damage, such as cracks, holes, or kinks in the hose. If you notice any, replace the damaged parts immediately.
  • Test for gas leaks: Mix a solution of soapy water and apply it to the hose and regulator connections. Turn on the gas supply, but don’t ignite the grill. If you see bubbles forming, it indicates a gas leak. In this case, replace the faulty parts to ensure proper gas flow.

4. Adjust the Air Vents:

The air vents on a gas grill play a crucial role in controlling the airflow and maintaining the desired temperature. Adjusting the vents can help increase the heat output:

  • Locate the vents: Depending on your grill model, the vents may be located on the lid, near the burners, or on the control panel.
  • Open the vents: If the grill is not getting hot enough, try opening the vents to allow more oxygen into the grill. This increased airflow can enhance combustion and heat production. However, be cautious not to leave the vents fully open for an extended period, as it may cause excessive heat.

5. Clean or Replace the Ignition System:

A faulty ignition system can prevent the burners from lighting up correctly, resulting in low heat or no heat at all. Follow these steps to clean or replace the ignition system:

Clean the ignition electrodes: Over time, the electrodes can become dirty or covered in grease, hindering their ability to create a spark. Gently clean them using a soft cloth or a toothbrush.

Adjust the electrode position: Ensure that the ignition electrodes are in the proper position, close enough to the burner for a consistent spark.

Check the wiring: Inspect the wiring connections to ensure they are secure and undamaged. If you find any loose or damaged wires, repair or replace them as necessary.

Replace the ignition system (if needed): If cleaning and adjusting the electrodes don’t resolve the issue, it may be time to replace the ignition system. Consult your grill’s manual or contact the manufacturer for the correct replacement parts and instructions.

How To Check a Gas BBQ for Gas Leaks

Checking a gas BBQ for gas leaks is an important safety measure. Here’s a step-by-step guide on how to do it:

  1. Preparation:
    • Make sure your gas BBQ is turned off and completely cool.
    • Ensure there are no open flames or ignition sources nearby.
    • Have a spray bottle filled with a mixture of water and dish soap ready. The soap helps create bubbles when gas is escaping, making leaks more visible.
  2. Gas Valve and Connections:
    • Start by inspecting the gas valve and connections for any visible signs of damage, wear, or corrosion. Look for cracks, loose fittings, or bent connections.
    • If you notice any issues, it’s advisable to have the faulty parts replaced or repaired before proceeding.
  3. Gas Hose:
    • Examine the gas hose that connects the gas supply to the BBQ. Look for cracks, holes, or frayed sections.
    • Make sure the hose is securely connected to both the gas supply and the BBQ. Ensure there are no kinks or bends in the hose that could restrict gas flow.
  4. Leak Test:
    • With the BBQ off and all knobs in the “Off” position, slowly open the gas supply valve.
    • Apply the soap and water solution to the gas connections, hoses, valves, and regulator. Ensure thorough coverage.
    • Observe the areas you applied the solution and watch for any bubbles forming. Bubbles indicate a gas leak.
    • Pay close attention to the connection points, such as where the gas hose attaches to the gas supply and the BBQ, as leaks are most likely to occur there.
  5. Detecting Leaks:
    • If you observe any bubbles forming while conducting the leak test, it indicates a gas leak.
    • In case of a leak, turn off the gas supply immediately and tighten the connection or repair the faulty part.
    • If tightening the connection doesn’t resolve the leak, it’s recommended to consult a professional technician or contact the manufacturer for further assistance.
  6. Regular Maintenance:
    • Perform routine checks for gas leaks on your gas BBQ periodically, especially before the grilling season starts or after any prolonged storage.
    • Replace the gas hose every few years or if you notice any signs of damage or wear.

Always prioritize safety when dealing with gas appliances. If you’re unsure about performing a leak test or detecting leaks, it’s best to consult a professional technician who can ensure proper inspection and maintenance of your gas BBQ.


A gas grill not getting hot can be frustrating, but with these six easy fixes, you can quickly diagnose and resolve the most common issues. Always prioritize safety by following proper procedures and turning off the gas supply before performing any maintenance or repairs. Regular cleaning and maintenance will help keep your gas grill in optimal working condition, ensuring many enjoyable and delicious meals for years to come.
