Why Does My Grill Clog Up?

Gas Grills Explained

• A gas grill uses natural or propane gas to create a flame. The gas flows into the grill through a hose connected to a tank or a natural gas source. The hose has a regulator on one end that controls the amount of gas allowed into the grill depending on the setting of the grill. Once the gas flows through the hose into the grill, it is released through holes on the burner jets. The grill is started when a spark is exposed to the gas flow, creating flame and heat used to cook food. If the burners are clogged in any way, the gas flow is interrupted to the grill.

Clogs

• Clogs occur in gas grills for a variety of reasons. Food cooking in the grill naturally creates burnt debris and grease, both of which collect on burner surfaces. These substances also gather inside gas outlet holes on the burners, clogging the holes. Another common cause of clogs in gas grill burners are spiders. Spiders crawl into the gas outlet holes and gas flow hoses to lay eggs or create webs that clog the opening. Spiders themselves also move into the holes and create blockages, as well. Spider clogs in a gas grill are common causes of gas grill flare ups due to clogs.

Clog Removal

• Removal of clogs in a gas grill is simple and straightforward. Remove the burners from the grill to check them all over for blockages. Once the blockages are discovered, use a paper clip or piece of wire to poke the clogs in the holes. This removes the clogs, freeing the holes for gas flow. Removing clogs from the gas flow hose requires detaching the hose from the gas source and grill. Use a long, thin brush to sweep away clogs inside the hose. These brushes may be purchased from stores carrying grills, home supply stores or hardware stores and provide an effective means of clearing grill clogs.

Burner Replacement

• Occasionally clogs in a burner are due to deterioration of the burner itself. Over time, the burners may develop rust and scale build-up on their surfaces. This build-up may clog the gas flow openings as well as eventually rendering the entire burner useless. Though minor rust and scale damage may be removed by cleaning the burner with a wire brush and scraper, the best option for this type of clog is to replace the burner with a new part. Check your grill owner's manual for advice regarding the exact replacement burner you need and where to purchase the part.
