Gas Grill: Why is my 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, because 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.

THESE REPAIRS MAY HELP SOLVE YOUR GAS GRILL PROBLEM

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.

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.
