I have a GE Mod jgbc20beh1wh which I believe is an XL44. It has all five knobs in a row which works the four top burner and the middle knob works the oven. I had a pro install a new Glow Bar over a year ago and now it won't go off when the oven knob is off. I smell gas so I unplug the oven and the glow bar went out. I call the Gas co. and the tech said that it looked like I had a bad selector switch but I can't find any manuals that refer to the selector switch. He check the stove with the gas flowing and there were no signs of leakage anywhere. Could this really be my problem?

no gas flow sounds like a bad gas regulato on the stove. as for the 5 year old ge profile with ignitors not working, you need a part called a spark modual

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:

1. Turn you burner to the Lite position:
   
   If you hear clicking or sparking, go to Step 2.
   
   If you do not, check your circuit breakers. If the circuit breaker is ok, we recommend that you schedule service by calling 1-800-432-2737 or schedule service online.
   
   
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.

it seems the burner in the oven is clogged, by grease, carbon or corrosion, it may need replacing, specialy if this is an older unit

SOURCE: oven won't work

Yes. The ignitor must register 2.9 amps or more to operate correctly and ignite the gas. Replace the ignitor.

Ignitor needs to be working for the gas valve to open. If the ignitor does not reach the proper amp draw the gas valve will not open. There is a video at www.appliancehelponline.com/servicemanual.html this will walk you thru performing an amp draw test on the ignitor.
