Gas burner will not completely lite

It probably has a flame failure device..
This is to cut off the gas if the flame goes out..
When you light the burner, the flame heats a sensor which keeps the gas on, if this is faulty, the gas will go out.

Hello there:
A burner doesn't work The most common problem for gas surface burners is that they get gas but don't light. This is generally caused by dirt or grease splatters on the burner itself. Residential-grade range/stove burners are round and have small holes around their perimeter to allow gas to flow out and create a round flame. The gas coming from these holes is often ignited by a small vertical row of holes on the side of the burner. If these vertical holes are clogged or obstructed, the gas can't ignite. The solution is to clean the burners thoroughly. Use a toothpick to clear the small vertical holes, then allow the burner to dry completely and try lighting it again. If it doesn't light immediately, either repeat the procedure or call a qualified appliance repair technician.

Electric gas igniters sometimes get stuck in one position causing a clicking sound. The clicking sound that you hear is the electric arc that is pulsing from the igniter conductor (wire) to ground (the gas burner). It receives power from the electrical outlet that the stove is plugged into.
Residue from food and sometimes cleaning products may be preventing the igniter from producing a spark (Arc) to the base of the burner. This is a common problem that occurs when the stove has been cleaned or food is allowed to build up. Make sure that the igniter and the burner base are clean and dry. This will help with proper operation. Oven cleaner and a small tooth brush may be used to accomplish this. Another problem with ignition may occur if you have too little (touching) or too much space between the igniter and the base of the burner; it will prevent the burner from igniting. You should only have a little more space than the thickness of a nickel between the burner base and the igniter. A good “blue” arc from the igniter to the burner base is optimal. If this doesn’t work, you may need to replace the electric igniter module. Good luck.

Go to RepairClinic.com and check on how much a new igniter is. Is there two or 4 igniters on your model (lift the top of the range up and it is the little silver piece sticking out with a white base around it), If its 2 is the other side working? Make sure there is no food deposits around where the gas and the spark meet.

it is strange that you have no gas and no spark! if you held a match to the burner and turned the burner valve on it would lite di spite a failed ignitor,but for it not to lite, the burner valve[its what the knob attaches too] would have to be blocked[thats rare]or ........i got it .....the knob is broken.thats the only thing the burner valve and the spark ignitor have in common.try a knob from another burner................again.you have spark,because others are working.spark on troubled burner would work if valve blocked at orifice outlet,and if spark failed you would still get gas they work independent of each other,[but in unison].thats why im thinking knob.its the item that works both .when you turn the knob it opens the gas valve and as the gas valve rotates by turning the knob it activates or turns the spark switch so it closes the curcit allowing the electricty to the spark moduel.hey i hope that helps a little. God bless ,tom

aknot, make sure each burner cap has a good ground to the burner. You can use some light sandpaper to scrub them. Where the burner fits around the ignitor is a small orfice. Use a paper clip or small sharp object to clean out the orfice. Try this first. Catriver..post back.

I have a viking gas cooktop. The ignitor on one of my front burners wouldn't stop clicking even after the flame ignited. I swapped that ignitor with the ignitor from a back burner, expecting that the problem was with the ignitor and that the back burner would start to click incessantly, but at least I'd have my favorite front burner for use. Instead, the front burner was then only clicking 50% of the time and the back burner was fine, suggesting the problem was related to the burner not the ignitor. I pulled the front ignitor a bit away from the burner and now it is working normally. Hope this helps.

Replace that ignitor on that burner only. Not drawing enough amps to spark properly.
