What to do when your Thermos gas grill isn't getting hot enough

Problems with gas flow can keep a gas grill from getting hot enough. First, make sure there's plenty of gas in the tank. The diminished gas flow from a nearly empty tank won't supply the burners with enough gas to heat properly. Our video shows how to check the level of propane in a tank. If the tank's full but gas won't flow freely to the burners, reset the pressure regulator. Replace the pressure regulator if it won't allow gas to flow properly to the grill after resetting the regulator.

Clogs inside the burner tubes or spills covering the burner tube ports can also inhibit heating. Clean the burner tubes so the burners heat properly and replace any damaged burner tubes. Perform routine maintenance on your grill to help keep the burners working efficiently. Also check and adjust the alignment of the burner tubes to the gas valves so the burners heat properly. Check the operation of the burner valves on the manifold and replace the manifold if gas doesn't flow properly to the burner tubes when you open the manifold's valves.

Top repair parts for Thermos gas grills

• Lid hinges. Lid hinges support the lid and allow you to open and close the lid during grilling.
• Lid handle. The lid handle allows you to open and close the grill lid while grilling.
• Pressure regulator. The pressure regulator on the supply line from the propane tank controls the pressure of the gas going to the grill. It often includes the gas supply hose and the fittings that connect the propane tank to the manifold.
