Change your gas regulator and connecting kit if it is more than a year old and living outside. The other possibility is, that if the unit is older, the burner holes have rotted out and become too large. Most grills have replacement burners readily available. Deal with the problem in the order I have presented the solutions and it should be just fine.

I recently had this problem too. I had my grill for over a year and never had this problem, then it started after I switched to a new propane tank. I took the tank to get filled, and before they fill a new tank they have to purge all the air out of it. I'm thinking they didn't get all of the air out of it because ever since, black smoke and soot are coming from the grill.

What does the thermocouple look like?


Note that sooting with yellow flame is the result of insufficient air (i.e. oxygen) mixing with the propane gas. You need to identify where do you open the orifice or neck where the propane gas is released to burner. Open this orifice wider to add more air mixture to your propane and you should be able to get the flame back to bluish color.

Best of luck.

Do i have to turn the propane off at the tank each time I turn the grill off or can I leave the propane tank open?


Hi
You can leave it open but you will loose your propane if you have even a small leak.

Grill does not get hot. I have a fresh bottle of propane. Hose is not kinked. Grill is maybe 6 - 10 years old.


hi,
When a new or newly filled propane tank is attached to your gas grill, the OPD is usually at its maximum limit position above a tank filled to capacity. Propane may come through the valve too strongly due to the additional pressure of being full and the OPD displacement. The propane tank goes into check and limits gas flow when too much pressure hits the valve. Some grill manufacturers provide instructions for this in the users manuals but most people do not read the manual. Many grillers believe replacement parts are needed and burners, ignitors and regulators get replaced without reason. Depending on how efficient the grill is operating, some grills attached to a tank in check will not ignite and others will light but cannot reach cooking temperatures because the tank has limited the amount of propane released. Sometimes the food will be unable to exceed 200 degrees in temperature because the propane tank is in check.


Gas grill replacement parts are available and are sometimes necessary, low or no gas flow indicates a different typr of repair. Most grillers accept instructions and the problem is corrected in minutes -- but believe it or not I have had a few insist on purchasing replacement parts.
How do I fix grill?
To reset the check valve and get back to cooking on your gas barbecue grill, first
turn everything off. Turn off the grill, the rotisserie, the side burner and the LP gas cylinder tank. Once everything is turned off disconnect the propane tank from the gas grill regulator by unscrewing it or pulling the quick-release on older or retro-fitted propane cylinders. Now turn the grill on. I know, it is dis-connected from the gas tank but we want to ensure that the pressure in the gas lines or any gas in the burners is released. Leave all grill burners in the on position for 3 - 5 minutes before turning them off. Make sure. Most gas grill valves must be pushed in to turn them and if turning is attempted without pushing the knob, they will not turn to the "on" position. With the grill, et al turned off reconnect the propane tank and slowly turn the hand wheel to the open position.
Slowly. The trick here is to turn the hand wheel slowly. Propane in a new or very full tank will be under more pressure, especially with the OPD floating in position. The extra pressure will come through the tank valve stronger. Turn the gas tank slowly allowing small increments of propane to enter the grill.


Once this is complete, you should be able to turn the grill on high and ignite your gas grill burner. Your cooking heat should be back to normal and cooking times decreased. If the problem persists, try this process again to make sure you followed every step. The check valve exists to save your life if there is a leak in any of the gas fittings. Constant check valve issues could imply a gas leak and a visit from your local gas grill service technician may be necessary.
To find a leak, turn the grill valves to the off position and the gas tank valve to the full on position. This should pressurize the gas line. Spray soapy water on all the fittings and look for bubbles just like checking for the leak in a flat tire.
Do not attempt to correct a gas leak on your own. While a check valve error when your gas grill will not get hot or will not ignite is a user education error and an issue corrected by learning about your propane tank, a gas leak should be corrected by a licensed gas service technician. When you are grilling, turn the propane tank on first and then turn on your grill. When you are done cooking, turn the gas tank off first and then turn off the grill valves. The process releases the pressure in the gas grill hose and manifold which allows the gas tank to release pressure by filling these lines. Read the safety features of your gas grill, clean it when necessary and replace used and failing parts. Aside from that be safe, eat well and have fun.

thanks.

My weber gas grill suddenly does not heat up enough. It has been working for two years and suddenly the amount of flame is tooooooo small to cook.


Hello. You may not have enough propane left in the tank for it to work properly, you may not have turned the tank valve to the full open position, or your valve safety device may have kicked in. IF this last item is what happened read on:
To reset the check valve and get back to cooking on your gas barbecue grill, first
  • turn everything off. Turn off the grill, the rotisserie, the side burner and the LP gas cylinder tank.
  • Once everything is turned off disconnect the propane tank from the gas grill regulator by unscrewing it or pulling the quick-release on older or retro-fitted propane cylinders.
  • Now turn the grill on. I know, it is dis-connected from the gas tank but we want to ensure that the pressure in the gas lines or any gas in the burners is released.
  • Leave the grill, side burner, rotisserie, etc on high for a few minutes with the hood open before turning all the valves back to the off position.
  • Make sure. Most gas barbeque grill valves must be pushed in to turn them and if turning is attempted without pushing the knob, they will not turn to the “on” position.
  • With the grill, et al turned off reconnect the propane tank and slowly turn the hand wheel to the open position.
  • Slowly. The trick here is to turn the hand wheel slowly.
When the propane gas tank is new or newly-filled, the gas is full and the OPD is pushing slightly on the top filled area and the gas will want to burst through the valve. Slow it down by turning the valve on slowly and the check valve will reset itself.

Gas dryer leaves black grease spots on clothes


the soot is coming from the flame at the gas heater box the drier needs to be converted to propane the flame is too large without the conversion kit installed and thus creates soot at the vent. contact a local repair place for this one it can be tricky.

Black is on the burners


the fuel to air mixture is set incorrectlty or your pressure at the ouitlet for the gas valve is too low.
you culd play around adjusting the first part of this but for the gas valve part you have to have a manaometer to check it out correctly. then it should be set at 10"wc. Good Luck

What could be wrong with a gas stove hot point(2 yrs old)that has lots of black in the oven when using and also black on bottoms of pans when using burners on top? it just started doing this...


The flame is 'yellow tipping'. This means there is incomplete combustion and will leave black soot on everything. Did you recently start using propane? If so the stove will need to be converted to propane use, or the incoming gas pressure is too high. You may need a gas professional to check the gas pressure.

Soot gathers on everything


The smoke will stop when whatever is on the brickettes is burned off. Leave the unit on high heat for about 10 minutes and it should clear it. If not, get replacement product.
