Gas Fireplace lights up but not all of front burners light up

SOURCE: Stove burner igniter does not work.

Your problem is not the igniter itself, but the burner switch that controls the igniter. All the igniters get their power from one spark module that is mounted somewhere in back of the oven. That's why you are able to get all the igniters to spark with only one burner control turned on. This is normal. That is also why you are able to light the burner in question buy turning on another burner. The spark is being provided by a switch that is working. To answer your question: the igniter is removable, but I don't think it's necessary. Cleaning them generally doesn't make them work better. I would check the wiring from the spark module to the burner switch and/or replace the switch. I hope this helps.

If your top burners are not lighting or will not work, it is possible that the burners have become dirty or wet. Please follow the troubleshooting directions below before calling service:

2. Clean the burner and electrode:
   
   First remove the burner grate, cap, and head. Use a needle or paper clip to poke through the holes on the burner head. Re-assemble and try the burner.
   
   Remove the burner grate, cap, and head. Even if it looks clean, wipe the tip of the electrode with a clean, dry paper towel and PRESS IT DOWN. Re-assemble and try the burner, again.
   
   Check to see if the burner works, If not, then go to Step 3.
   
   
3. Re-assemble - Make sure that each burner top matches its burner bottom. The burner top will lay flat if put on correctly.
   
   Check to see if the burner works, If not, then go to Step 4.
   
   
4. The spark igniter is operating properly, but the burner is still not lighting. At this point, we would recommend that you schedule service by calling 1-800-432-2737 or schedule service online.
   

SOURCE: Gas Fireplace pilot light continually goes out

You may have a problem with the flame sensing capillary. It may need to be replaced, or it may need to be positioned into the pilot flame better, or you may need a new gas safety valve. Sometime there is an adjustment screw for the pilot which can make the flame bigger or smaller. If will be on the safety valve.
