Gas Grill: Not 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.
Clean, repair or replace the gas grill burner
Regularly check and clean the burner tubes of spider webs and debris. Clean the burner tubes with a bottle brush or stiff wire, such as a straightened coat hanger. Check the gas ports (holes) for spills that could glog them. Clean the burner if necessary. Look for rust or damage on the burner bodies and replace a burner if it's damaged or rusted.
Replace the gas grill pressure regulator
If the pressure regulator isn't working properly, first reset the pressure regulator, following the instructions in your owner's manual. To reset most pressure regulators, shut off the gas supply valve at the tank, disconnect the hose/regulator from the tank, wait 30 seconds and then reconnect the hose/regulator. Slowly open the gas supply valve on the tank. If the regulator still doesn't work properly, replace it.
Perform routine gas grill maintenance
The gas grill needs to be periodically cleaned and adjusted to work well. Clean the flavor bars. Check the burner tubes and replace if damaged. Clean any clogged ports on the burner tubes and the inside of the burner tubes. Check the alignment of the burners and igniters.
Replace the gas grill manifold
The manifold on a gas grill has the burner control valves and the connecting gas tubing. If the manifold fails, burners won't heat sufficiently or won't light at all. If a valve is stuck and not working, replace the valve. If the individual valve isn't available as a separate replacement part, replace the entire manifold.
Adjust and align gas grill components
Remove the grates and the flavor bars. Check the alignment of the burners. Make sure that all fasteners are in place. Check the igniter electrode. The tip of the igniter should be within 1/8- to 1/4-inch of the gas burner. Adjust the igniter if necessary.

You can install a new pressure regulator on your gas grill if the pressure regulator won’t let gas flow.
A conversion kit and a few simple tools are all you need.
Clogged or corroded burners and flame tamers could be the problem.
