  A gas grill is the focus of backyard gatherings all over the country. Some people prefer the gas grill because of its even cooking, while others simply appreciate its ease of use over messy charcoal. As straightforward as a gas grill is, problems occasionally arise when using it. Learn how to troubleshoot your gas grill and help keep it working properly.
  
  

Uneven Flame

• A consistent and even flame makes for efficient cooking. If you notice an uneven flame in your gas grill, something could be blocking the burner tubes that run under the cooking surface. While the grill is off, take a steel brush and clean the burner tubes' small holes. These small holes are where the flame comes out. Once you have cleared the burner tube holes, you should have an even flame again.
  
  

No Flame

• There are several possible reasons for not getting a flame when you try to ignite your gas grill. If you have an electric starter, replace the battery. The propane hose from the tank to the grill may have a leak. Mix dishwashing soap with water and apply it to the connections and the hose itself to check for leaks, according to the Barbeque Lovers website. If you see bubbles in the water when you turn on the gas, you have a leak. If the leak is at a connection, tighten it. If the leak is on the hose, replace the hose. The first thing to check for, though, when the gas grill won't light is whether or not you have propane in the tank. If there is no level indicator on the tank, this can be next to impossible for the homeowner. Take the tank to a propane re-filling station and have it checked and refilled if necessary.
  
  

Constant Low Flame

• Some models of gas grills come with a low-flow mode that limits how much gas the burner tubes get, according to Home Furnish website. If you are getting a low flame in your burners no matter how much you open the propane tank's valve, then you may be experiencing low-flow mode. Turn off all of the burners and disconnect the propane hose from the grill for 30 seconds. This helps reset the regulator inside your grill and turns off low-flow mode. After 30 seconds, carefully reconnect the hose to the grill using a wrench, making it as tight as possible. Low-flow mode kicks in when the regulator senses air mixed in with the propane. This could mean that the connection at the grill was not tight enough. If you are still getting a low flame after resetting the regulator, then your hose or propane tank may have a leak that is allowing air into the system and triggering low-flow mode.
