Want to replace the gas valve

Hi and welcome to FixYa, I am Kelly. On the burner your having problems with the ignition control switch located in front of the gas control vale on the stem has failed. These are cheesy little switches that are thin ceramic with nothing but 2 strips of copper inside them. One piece is fixed and the other piece is movable by the ceramic switch cam. If the movable copper arm or fixed copper strip gets bent the ignition will not shut off. Also if the ceramic cam of the switch fractures it will cause the switch to stay actuated. The gas valve has to be disconnected and removed to change the switch on most units. The wires in the switch have to be unlocked by inserting a jewelers screwdriver into the holes in the switch body to release the wires. These switches are common to most every gas cook top models no matter the brand. Without your model number I can not provide you with the manufacturers replacement part number. Change the burner ignition switch on the front of the gas valve for the burner with the problem and it will work fine.

Hi and welcome to FixYa. I am Kelly. On your cook-top the gas igniters are cycled on and off by a ceramic and copper switch on the front of each of the gas valves. Some of them are in wired Series ...i.e any burner on will cycle all igniters on the cook top and some of them are in Parallel where individual burners are controlled by each gas burner control knob. Inside these tiny ceramic switches there is a flat thin strip of copper that as the gas valve is rotated a cam of the switch actuates pushes the copper strip against the fixed contact. Those little strips over time either break or get bent and stay against the fixed contact. Hence you have and igniter on when the burner control is off. The only fix is to find out which little ceramic switch on the front of the gas valve is stuck. You do it with an Ohm meter POWER off. They all should read open with the burner controls off. The one that reads continuity across the 2 wires is the bad switch.

Thanks for Choosing FixYa.

Hi, the valve stem on a gas stove is on a manifold assembly under the top. If I am correct in remembering, the burner valve unscrews to replace them. If so, take it with you along with all of the numbers,M#, S #, and so on. Best of Luck,

1) turn off power at the breaker. 2) remove hold down screws 3) pop up cooktop out of counter top 4) remove knobs and downdraft grille 5) remove ceramic top (screws around outside and also in side grille opening) 6) unplug burners replace with new burner

hi...no nid to replace the ceramic top,coz it is very expensive compare to buy a new one.the price of the glass ceramic top is mostly half or 3/4 of the actual price of the new one.much beter to buy an new one,get an new & the warranty but the glass is not covered in waranty for all brand.

much beter to call an technician coz the glass ceramic is no warnaty,if u get wrong instalation or broke the glass u waste ur money,call the person have an expertise for that.dont try to fix by it ur self.coz if the technician fix it,u get an assurance for the waranty if may happen during instalation.

Hi

If the burner is not burning hot, and there is a low flame then this is often a pressure regulator problem. Most often the regulator is found where the gas line enters the gas range. I have a picture of what the flame characteristics should look like. If the igniter on different burner doesn’t work, and there is no spark at that burner then you will have to check the same items as mentioned above. This is a typical spark module wire diagram.

Please do accept the solution if the issue is resolved or else revert for further assistance.

First i should say it is very dangerous to preform gas appliance service if you are not trained. if you have evin the slightest question in your own abilities ALWAYS call in the pro's. However I think I can help. 1st turn off and disconnect gas. remove cook top from counter and lay on towel top down. Sense this is glass top there is no service from top. there are a series of screws that go around the perimeter of bottom. remove these screws. The bottom should lift away. this will allow you to change components. hope this helps and good luck.

As it relates to 5 burner gas cooktop Model Number JGP 963SEJ1SS
First - Ignite the flame then reduce the flame to between low and medium.  If the igniter continues to click, you most likely have a contact switch issue related to the problem burner.  
Unplug the cook top and turn off the gas.  After the gas is turned off, disconnect the gas line.  
Remove the cook top.  

Unscrew and Remove ALL of the burner bases by lifting them up.  The ceramic igniters may be difficult to remove but they will come loose if worked out slowly.  
Pull of the wire connected to the igniter. 
Remove to cook top top plate from the base, exposing the internal gas valves and wiring.
All of the burners are wired in parallel.   Lift off and unsnap the casing of the problem igniter switch.  The repair may require something as simple as, 1- cleaning the contact strips, or 2- slightly bending the non stationary contact strip to keep it from coming in contact with the stationary contact when in the off position, or 3- replacing the switch. 
Unless you comfortable and understand how electric systems and switches work, this is a job for a qualified repair person. 

Sounds like the switch electric sending unit needs to be Ither cleaned and dry good or replced. It's not hard at all, They are located under the knob switches, you will have to remove the knobs and the top cover, they look like a small square box wit a hole in the middle with two wires on the sides, just unplug the wires and lift the box off the switch rod. cleane them and dry them good and put them back.......that should do it.....Good Luck
