Grill Repair

  • The propane tank of your grill is appointed with an Over Fill Prevention Device is commonly known OPD. There are very minor chances that the OPD of your tank may be damaged that may cause your tank not to work properly. You would need to replace the part is it is damaged.
  • Another common problem that you might find is that vent holes of your regulator usually gets clogged which may prevent fuel from flowing properly and thus it would create trouble. This problem can be solved by blowing/tapping in the vent to remove clogging.
  • Regulators of your grill are linked to a flexible hose O-ring that gives regulators an airtight seal. Your grill may be creating a problem because of a damaged hose or ring. To check for leakage, take equal proportion of dish soap and water and coat tank, control valves and everything around. You need to have the tank connected and turned on and have the control valves turned off. This way you will be able to find if there is any leak and can replace that part.
  • Control Valves of the grill are there to control the fuel flow to the burner. All the burners have their own control valve and there are many different parts in each control valve that are designed for various fueling functions. If there is something wrong in your control valve, you would not be able to repair it and would need to replace the entire unit. Before making your way for replacement, remove the control valve and check. Grills are usually eased homes for insects and control valve is one of the places where they make homes. In the center of the control valve, there is orifice. If this part is clogged, it would hinder flow of fuel. You can clean it using a thin wire and put it back carefully. Remember that without orifice, gas flow to the burner is not controlled and it could result in an explosion.
  • Venturi tubes are connected to the control valve of your burner. These tubes are responsible for mixing fuel with air that produces a flame. There exists an open gap in the lines of the fuel where mixing is done. These tubes can get obstructed by insects and whenever they get a chance, they can move in this place. You can prevent that from happening by wrapping the tubes with the aid of an aluminum screen. Using this screen would not block the flow of air and would keep insects away. Many of the gas grills now come with secured tubes.
  • Apart from this, another problem with venturi tubes could be a misalignment with the burner. They may be placed out of their place. Usually the tubes have shutters that are adjustable and you just need to adjust them to their correct place for regulated flow to fuel.
  • Different grills have different burners and you may find some low-end aluminum steel burners to cast brass or stainless steel ones too. If your grill is appointed with a low-end burner, it may last up to 3 years however with time the burners usually get a coat of burnt grease and may get rust quickly. You need to carefully inspect burner and clean it. If you find it is heavily rusted and could not be cleaned or if it is damaged, then replace it.
  • If you are experiencing a low flame or if your grill is not heating up, there can be different things that may be causing this problem. Usually when your tank is new, the self-regulating feature of the tank automatically lower down fuel flow when it considers that it is too high. In that case tank valve should be turned off and disconnected. Also open the control valves and then close them again. Now reconnect tank and turn the valve on slowly. Check the flame by lighting the grill. If it still doesn’t fix, check control valve and venture tubes for any clogging or misalignment. Ensure that the flow of fuel is continuous. Also check burners gas holes. They may be clogged or damaged.
  • You may be experiencing an uneven heating problem with your grill. Some parts may be getting extremely hot while others remain cooler. This one is similar to the problem of having a low flame. Repeat the same steps for the solution. However if your grill has multiple burners, check is some burner is getting hotter than the other one.
  • Your grill is offering a yellow or orange flame. The flame should always be blue with tips yellow. If you are experiencing a yellow/orange flame, there is some problem. Clean the burners and let them burn with maximum temperature for 10-15 minutes. Check venturi tubes for alignment. Check venture shutters for proper adjustment. The adjustment can be done by releasing the adjustment screws, lighting the grill at low temperature. Loosen screw and shutter should be opened until the flame color turns blue. Turn the gas off. Tighten the screws back.
  • Your grill is producing a lot of smoke. Smoke is a sign of large accumulation of grease inside your grill. Clean your grill thoroughly and preheat it for 10-15 minutes for burning off any residue.
  • You are noticing flame from under the grill and behind the control panel. Any sort of misalignment and clogging of venturi tubes would be responsible. Let the grill to cool down and inspect to see if all the parts are in place. Also check fuel lines and hoses for any leakage or damage.
