Avoiding Common Grill Problems
Corroded and Rusting Parts--To avoid this problem, make sure you keep your grill covered up well with a waterproof, perhaps even a felt lined grill cover. Do an occasional clean up of the internal grill parts and store the grill inside if possible, though be sure to keep the propane cylinder outside.
Problems with the Burner not Lighting--If your burner is having trouble lighting, begin by cleaning the venturi, double checking the LP Units or the Natural Gas units by either filling the LP cylinder or turning on the natural gas source. Put the venturi over the orifice and clean the components. Double check the position of the ceramic electrode in the burner gas collector and also check the condition of the ignition wire, the ignition wire connections to the electrode and ignition and replace any parts that are damaged.
The Grill is Too Hot--If you grill is putting out an excessive amount of heat, be sure to double check your manual on taking care of grease fires so you know how to handle that should the need arise. Make sure to replace any damaged parts your grill might have. Clean the grill thoroughly and replace the grease can. Reduce the cooking setting. Place the orifice into the valve assembly, replace the burner, and check the tank for overfill. Also, remove the grill from direct sunlight on the hot days and also when it has been recently filled up.
Gas Leaks--If any of the gas parts are damaged, they could allow gas to escape, so be sure to replace any part that bubbles when a soapy solution is applied to it.
Humming Sound on the Grill--A humming sound is caused by liquid propane passing through the regulator. To fix the problem, have an LP dealer "bleed" the tank of some propane. Another solution could be to have the propane expand in the event the tank was filled in a cold temperature. Replacing the hose or regulator could also solve the problem.
Whistling Sound on the Grill--If you hear a whistling sound, it is probably when your grill is on the "high" setting and the existing orifice will need to be replaced with a new one.
Yellow Flame--If you see a yellow flame, there are several things you can check to see if they are causing the problem. Clean the venturi. Then check for residual oil by operating the grill for 15 minutes or until it stops smoking. Clean the burner. Also try using up a tank of propane as the yellow flame could reduce during the use. Another option is to place the venturi over the orifice.
Flame that Blows Out When on a Low Setting--If this happens to your grill, begin by preheating the grill for 5 minutes on its highest setting. Clean and reposition the venturi. Have the cylinder refilled. Also, try turning the grill away from the wind and turning up the control knob to a slightly higher setting to see if that takes care of the problem.
