Question about Ducane 30400042 (LP)

1 Answer

When I try to start the propane grill (Ducane)by pushing the knob and turn to hi, it creates a spark and from the "pilot" there is a big flame straight up, I hear and can smell the gas , but that flame can not fire the burners and they does not start unless I use external source close to the burners. Why this huge flame for the "pilot" can not fire the burners? This problem started recently for all 5.

It sounds like something got disconnected between your gas line and your venturi (which deliver gas to your burners. Take out the grills and whatever holds your rocks or ceramic briquettes and look at the connection where the flame is coming from. It may be obvious what has come apart, and the fix may be as simple as pushing it back together.

POP OFF A KNOB AND LOOK TO SEE IF THERE IS A TINY SCREW IN THE CENTER OF THE KNOB SHAFT . THAT WOULD BE YOUR ADJUSTMENT FOR GAS FLOW. IF IT'S NOT THERE, THE PROBLEM IS IN YOUR REGULATOR, AND IT'S ADJUSTABLE AS WELL.

Good answer... but remember (if you have the regular burners on... The Rotisserie will not light.) 1. Cut all knobs off... Then push and hold in Rotisserie button as you turn to high.
2. Press ignition button, until you hear rotisserie ignite. 3. Keep holding in the rotisserie button until the thermostat realizes the gas is on and burning. (IT must get hot enough to keep gas flowing.) Hope that helps, Dave

SOURCE: low flame

Either ;
1 your valve is not opening on your tank,
2 your regulator is bad on your tank, or
3 your out of gas.

Unless your second burner is going fine then you have :
4 a bad burner valve control not opening or
5 Some cobwebs inside the burner blocking the gas flow.

If this helps you please rate me with as high a mark as you can. Thanks for using Fix ya and Good Luck

SOURCE: I have a ducane grill and it will not get hot. I

The most common cause of reduced flames is a pressure problem. Could be the gas regulator for the grill. When the burners are on try giving the gas regulator a tap with something hard and see if they change size. If they do then the rqulator could be sticking. And there is a very small hole on the regulator called a vent. If this hole gets plugged with dirt or grease you can get a low pressure problem. Look very carefully on the regulator housing for this small hole and verify that it is clear. Try using a small metal wire(like a tie strap for sandwich bags) to make sure it is clear. Also verify that the tank(if propane) is not overfilled. An overfilled propane tank will cause a pressure problem. You can turn the relief screw on the propane tank until no more liquid comes out to see if this fixes your problem.

The burners do not light consistenly. I can see the igniter spark and the fuel supply is good. If the igniter does work the main burners may not light until I creat a draft then the burner takes off.


It sounds as if, the burners need to be removed and thoroughly cleaned. As do the Venturi valves on the open end of each burner. Spiders like to build nests in the Venturi openings and clog them up. It's a prat of Routine Maintenance, takes a little time to perform, but is not difficult to do. It does require removing the burner knobs and the control panel cover (which was a poor design by Ducane/Weber)

To help make this a little easier for you, I have included a link to a Ducane Stainless Steel Model Grill that will show you how to remove the burners. Pay particular attention to the Annual Maintenance section starting on page 21. You can download and print this manual for future reference.

Hope this helps you. Please let me know and Happy Grilling!!

Burner igniters spark but do not ignite the burners. Do I need to replace them or is there some way to clean something. Also, the rotisserie burner will not ignite, and it has never been used.


All the ignitors work (spark), but none of the burners light ... is usually caused by and inadequate gas supply. Since you didn't didn't mention what the grill is fueled by (Natural Gas or Propane Gas), I going to assume it's Propane. So, turn the propane tank valve to OFF and disconnect the hose from the tank, Wait 5 minutes and reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (slow motion, slow) , until it's fully open. Try lighting the burner farthest from the tank first. If it lights properly, turn the burner knob to the highest setting and continue to light the remaining main surface burner(s) the same way. If all lightt and the flame height is as it should be, you solved the problem. If it doesn't, either your tank is empty or the grill hose/regulator assembly needs to be replaced. You can purchase one from any home center or hardware store that sells gas grills. Take your old one with you for comparison.

If it's fueled by Natural Gas, make sure the gas line shutoff valve is turned ON all the way.

Hope this helped you to solve the problem.

Propane is venting from regulator


Your propane regulator is defective and will need to be replaced. Do not use it. Contact your local propane co and bring it in for a replacement. Some retailers like K-Mart, Target or Wal-Mart will also have regulators, but if yours if not standard, it may need to be ordered by a Ducane grill reseller like Amerigas Propane, which is the largest propane co in the U.S.

Propane gas flame is not hot. Do I adjust the air


Here is something to try if it is LP Gas:

Here is a Tip to fix a grill that not getting hot:
1. Turn the gas valve knob off. then close LP tank valve knob.
2. Unscrew the plastic hose coupling knob from the LP tank. You may hear a slight "hissing" sound as pressure is released this is normal.
3.Wait a minute then screw the coupling knob back on to LP Tank.
4.With lid open.slowly open LP tank valve.
5.Relight the grill the proper way by turning gas valve knob to ON position while turning the igniter knob at the same time.
6.After you are sure the grill is lit preheat the grill for 30 minutes.

This was called purging the line or releasing the air out of the line.

Another thing your orifice could be clogged with spiders or dirt. If it is LP gas check to make sure your hose is not kinked.

I can't get the rotissorie burner to light. I have gas, all of the other burners light, the igniter sparks. Just can't get it to fire.


first turn your rotisserie knob on and then push it in, hold it down and push your starter while you hold it when it lights keep the knob down for about 15 to 20 seconds it should do the trick
