Why is my Weber grill not getting propane? Or Why is my gas grill not getting gas? Exact information on the subject is coming, for which you will have to read till the end.

Cause of Weber Grill Not Getting Gas or Not Heating

Often we do not use manual in this type of problem, which makes the problem appear bigger. Let us understand that the Weber grill does not heat up and what is the reason why the gas supply does not reach the grill. Both will be taken together as they are connected to each other.

Regulator Issues & Safety Mechanism

Weber Grill Not Getting Gas or Not Heating (Guide How To Fix)

In 1995, a federally mandated safety device designed to detect gas leaks began to be placed inside the hoses/regulators of every Weber gas grill. You see a regulator nozzle with an arrow pointing to the safety device in the photo above.

If your Weber propane gas grill is not getting gas or the grill is not heating up, you may have inadvertently turned off the bypass protection mechanism in the gas regulator.

The regulator sits between the gas tank and the hose. If the regulator detects any kind of gas leak, this mechanism works and shuts off the supply of all gas.

If your grill doesn’t light in a very specific way, the safety device will “think” the grill has a gas leak and reduce the gas flow from the tank to about 10% or less of its normal volume.

With so little gas accessing the system, it would be impossible to bring the grill up to its normal temperature range, or in some cases, the grill would not light at all.

Because you don’t know this mechanism and how it works then it can become a big issue for you.

Fixing Issue


Your safety is our first concern; So if you find a gas leak then turn off all the gas knobs, and regulator, and do not use the grill. We recommend asking an expert.

Before calling the expert, we have given you some guidelines which will help you out by bypassing and avoid going into bypass problems in the future.

Follow some easy ways to avoid going on bypass.

  • If the lid of the gas grill is closed, make sure the lid is open
  • Shut off the gas from the tank, as well as all control burner knobs, including the side burner knob.
  • Turn on the gas supply by opening the valve
  • Wait a few minutes for the pressure in the tank and hose for normal operation.
  • Go ahead and turn on the burners so you can ignite them normally.
  • Light all main burners and set to high temperature and then close the lid. Wait about 10 to 15 minutes and it should be in the 500 to 550 F range, which means your grill is now working properly.

Noted; The time taken to equalize the pressure of the gas completely depends on the weather. If you’re grilling in cold weather, it can take time to equalize the pressure.

You should give the hose/regulator some extra time to build up pressure before moving the burner to a mild Weber grill.

There are a few other things to check if these guidelines don’t work for you.

  • Have you checked that there is gas in the propane tank?
  • Is the hose/regulator securely and properly fitted in the tank?
  • Somewhere when you start the grill you put the knob on the low temperature rather than the high-temperature position. Is it possible that you are setting the grill to low instead of high?
  • You should inspect the thermometer once because it is possible that the thermometer has failed.

If all these tips and instructions are not efficient in resolving the problem then please contact your weber grill specialist. If you do this yourself, you and your family may be in danger.

Clogged Hose

A simple kinked burner tube can block the gas flow, adversely affecting the process of heating the grill. Here you need to check that the hose has become necessary.

You can easily fix these problems by simply removing the hose pipe and the clean gas line between the tank and the burner.

When you leave a Weber gas grill outside for long periods of time and don’t care for it, spiders build webs in hoses or clog gas lines by collecting debris in the form of dust.

Follow the Instruction to fix issues

  • Turn off the propane tank.
  • Remove the regulator and hose from the tank.
  • Soak the hose in the soap and water solution and use a wire saw to clean as much of the inside of the hose.
  • Reassemble the grill and see if that solves your problem.

Watch the video on How do you clean the gas tube on a Weber grill.

Burner Problems

If your burner is not working properly, it will not allow the flame to reach the highest temperature. This is because the orifice through which the flame exits has become small or that fat and grease dripping onto the burner tube from foods can clog it.

Because it is not cleaned, over time it keeps making the hole in the burner so small, due to which the size of the cooking flame is reduced. Remove your Weber grill and set them aside.

Follow the Instructions

  • Give your burner a good wipe down using a mild solution of degreaser and water.
  • Use your cleaning brush to scrub off any accumulated grease.
  • Reassemble the grill to see if this solves your temperature problem.

Fuel Supply

A Weber propane grill that isn’t getting gas and is not heating up may also simply be suffering from a lack of fuel. Even when empty propane tanks are heavy, making it is impossible to predict whether there is gas.

It is possible that there is still some liquid propane in your propane gas tank, empty or almost empty. Connect a full tank to see if the problem resolves on its own. Also, use a propane tank gauge.

How do I know if my Weber regulator is bad?

  • If the burners of the weber grill light up unevenly. Burner flickers or barely burns.
