Gas Grill Repair

How To Check a Gas BBQ for Gas Leaks 
It only takes a few moments to check for a gas leak. We recommend that you check for gas leaks each time you connect your regulator or natural gas hose to the barbecue, or after long periods of storage. 
Follow these steps to test for a gas leak: 
Make sure your gas supply is turned off and all control knobs are in the OFF position. 
Inspect all hoses on the grill, looking closely for signs of deterioration such as cracking, abrasions, holes, or tears. Ensure all the hoses are tightly connected and that there are no sharp bends or kinks in the gas line. 
Check the gas cylinder for rust, dents, bulges, corrosion, punctures, or other signs of damage. 
Mix a 50/50 solution of water and dish soap and apply it to the gas hose and connections points with a spray bottle or with a clean brush. 
Open the gas supply, but do NOT turn on the control knobs or light the grill. Do NOT smoke while testing for gas leaks. 
Inspect the hose and connection points. If you see growing bubbles forming at any point, this indicates a gas leak. 
Turn off the gas supply. 

How To Fix Low Flame and Low Temperatures 
If you’re experiencing low flame and low temperatures, start by resetting your grill’s gas regulator. All gas grills have a propane regulator that controls the flow of gas from the propane tank to the grill, and this regulator is one of the most common reasons why a bbq is not getting hot enough. 
Since the mid-90s, all gas grills regulators must also come equipped with a safety device called a flow-limiting device, or “Overfill Protection Device” (OPD). The flow-limiting device prevents the grill from being overfilled with gas or releasing more gas if it senses there is already gas trapped in the line or manifold. It’s easy to inadvertently activate this safety device even if you don’t have a gas leak, especially if you turn on the control knobs before you turn on the propane tank valve. In this case, the safety valve will not fully open until the gas pressure has been equalized between the tank and the grill, and your grill is in something called “bypass mode”. When this happens, your grill will only ever reach temperatures between 250 and 300, even with all the burners turned to the highest setting. 
Inadvertently triggering your grill’s “bypass mode” is one of the most common causes of low flames and low temperatures. Don’t worry—resetting or adjusting the gas grill regulator and flow-limiting device is easy and only takes a few moments. 

How to Check for Loose Connections 
If you have high heat but it’s uneven or you’re seeing yellow or orange flame, the venturi tubes may not be properly aligned or they may be obstructed by food debris or insects. That means it’s time to check for obstructions or loose connections. 
Start by using a bottle brush or special venturi brush to clean out the gas tubes—spiders and insects like to set up shop in these tiny tubes and are a common source of blockages. Once you’ve cleaned them out with a brush, follow these steps to check the connections: 
Locate the venturi tube adjustment screw you’ll use to release the shutters in step 3. 
Light the grill and turn it to low. 
Loosen the screw and open the shutters till the flame is mostly blue. 
Turn off the gas and tighten the adjustment screw. 
Let your grill cool. 
Once the grill has cooled, you can check the burner for clogged gas holes. Drippings can run over the heat plates and burners and clog the ports. These are usually spotted by observing how the grill burns—if there are spots without flames, you might have a clogged burner. If so, all you need is a wire brush to remove these deposits and restore normal gas flow. Simply clean the burner with a brush or let it burn on high for 15 minutes.
