Gas grill troubleshooting

Have you ever had your Weber gas grill light, but not give off enough heat? Usually, this isn’t cause for concern. Weber grills have a built-in safety mode.  When a burner is accidentally left open, the regulator restricts the amount of gas that can flow through the burner heads, to prevent a potential explosion. 

  • To reset the grill, turn ALL burner knobs to the off position.  Double-check that the knob for the side burner is off, if applicable.
  • Disconnect the black regulator hose from the gas tank and leave it disconnected for about one minute.
  • Reconnect the regulator hose to the gas tank.
  • Open the hood.
  • Try lighting a burner.  The ignitor may click a few extra times, but it should light with a normal flame.

Are you having trouble lighting your grill? If the grill can be lit by a match or lighter (click here for a tutorial), the ignitor is the likely culprit. Since propane fuels the grill itself, many people forget that the ignitor runs on batteries that need to be replaced periodically. Check the battery terminals for corrosion, and be sure that the batteries are inserted in the correct direction. You should hear a clicking sound when the ignitor button is pressed. Check the wiring to make sure the ignitor connections are tight. If the batteries are new, the wiring looks good, and the ignitor is still not lighting the grill, you may need to replace the ignitor. You will need your grill’s model number to get the right ignitor. Click here for help finding your grill’s serial tag.

Another common error that grill owners make is misjudging the amount of propane left in their tank and running out while cooking. The average grill will use about 2lbs of propane to cook a meal. This number will increase when using all burners of a large grill, plus a side burner, or when doing a long, slow roast.

Make it a habit to check the propane level after each cooking session, when turning off the tank’s valve. When the tank level shows about 2lbs of propane left, remove the tank and make plans to swap it for a full tank before the next time you plan to grill. Keeping an extra, full tank on hand is a great idea, too, especially if you often grill for a crowd.
