Burners two and three will not light unless direct flame is put to it. Burner 1 will light off the ignitor.

Check to see gas pressure, also clean all burner

I am not sure, but I think the Brinkman uses the ignitor to light one burner and the other burners light after the first one allowing the flame to "crossover".

Ronald, I doubt that the gas regulator has much to do with this problem, unless the tank valve is turned OFF or the gas tank is empty Have you tried match lighting the burners, to determine if you're getting gas to them? Also, check the spark ignitors at each burned for a grease build up. using a cotton ball and alcohol clean each ignitor tip.

If you've checked all of the above and you're now getting a spark at each burner, but little or no gas to the main burners, do the following:

Turn the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve ON VERY, VERY SLOWLY (slow motion, slow). Once the tank valve is fully open, light the burner farthest from the tank first and turn the burner to the highest setting. Does the flame height look correct? If so, light the remaining burner(s) the same way. Does their flame height look correct? If so, you solved the problem. Remember to always turn the tank valve ON very, very slowly.

Happy Grilling!!

Be certain the openings in the burner are free of debris. Boilovers can leave debris in the openings that will harden. Once this happens you cannot get the right mix of oxygen and gas for a flame to ignite. With the burner OFF, you can clean the openings gently with a toothpick to loosen the cooked on "gook." Then when you turn on the burner, the flame should burn off the residue and your range will be "cooking on all four burners!"

Hello, there is a carry over tube that looks like a burner hold down at the back of the grill. This is likely rusted closed and will need to be cleaned or replaced. The clips that hold the tube down are part # 7000132 and the tube part # is 7000279. They can be purchased directly from Char-Broil or Sears parts.

Sounds like a flame rod issue or the flame is not getting to it in time. The flame rod is located either far right or far left in the burner box and has only one wire going to it. It should be in line with the flame on a burner. The computer allows only a second or two for the all burners to lite and to get to the flame rod. Check the flame travel from burner to burner. You may have to clean the burners, the flame tray to each burner and the flame rod. Also check any electrical connection at the flame rod, circuit board and the grounds to the furnace cabinet.

Between the burners is a small rail in the pressed steel where the flame runs across to light the other burners and it sounds like there is dirt or debris in the step over rails causing the problem. You will need to use some compressed air on those rails to clear them out. Once the rails are clear the other two burners should ignite right away.

Hi!
First of all does this unit uses a hot surface ignitor or a spark ignitor? A hot surface ignitor is a resistive element that will get hot enough(glows yellow to near white) that ignites the main burners directly and a spark ignitor will light a pilot light first then that pilot light will ignite the main burners.
If your system uses the hot surface ignitor then there will be a flame sensor on the last burner that lights. This is a thin silver metal probe that is actually in the burner flame when that burner is lit. It is held in place normally by a 1/4 inch screw. It will have 1 wire attached to the end by a female spade connector. You can pull this wire off before you remove the flame sensor to clean it. Use a fine emery cloth to lightly sand off any residue on it. Also you will need to clean the end of that burner that the flame sensor serves as this is normally the grounding field. This is most likely the problem with your system if it is a hot surface ignition type.
If your system is the spark type then the problem is similar. Normally the pilot light is toughing a small flame sensing probe that is next to the pilot light. This probe also has to be clean. One more thing to look at is to see if the pilot light is large enough to surround the flame sensor. If the pilot is weak it will not touch the flame sensor enough and the system will do what it is doing for you now. If the pilot is weak then the pilot orfice is restricted. This should only be looked at and repaired by a qualified service technician. I hope I pointed you in the right direction!! Good luck!!

Sounds like your cooker has a flame rectifier supervision system. What this means is, electricity is passed through the flame from the controller, back to the controller/pcb (fire conducts electricity). If the the pcb doesn't recieve a return signal, it thinks the burner has gone out and starts the ignition to try a light the burner again. As simple to fix as a rusty/dirty flame rod or, as complicated as a bad pcb. Get a pro to check it out.

Not sure, but sounds like you may have a gas pressure problem or the stove is set-up for the wrong type of gas.
