Product review (5 stars): Exact fit 2002 GE XL44 range
My oven wouldn't light, and after a little research, I discovered my glow bar wasn't glowing, and as a result the oven wasn't either. After I pulled the stove out I found the parts list/manual sheet on the back of the stove. Yours should be there unless some dummy took it off. Found the part number for the glow bar/oven igniter and hit the net. Amazon had the best price of course....
 This glow bar is an exact replacement for my range, which is a 2002 GE XL44 range. And it was inexpensive.
I accept no resonsibilty for your mechanical skills. It shouldn't take much to do this anyway.....

 The swap was simple. You will only need a straight slot screwdriver and a 1/4 inch socket or nut driver (if you have a screwdriver with the removable tip bits, when the bit is removed, thats a 1/4 inch).
Unplug the oven.
Turn off the gas valve to the oven.
Remove the baking racks.
Remove the bottom bake shield by taking the two screws out in the very back bottom of the oven with a straight slot screw driver.
Push the tray to the rear until it comes out of the slots in the front and lift it out.
You will see the burner bar running front to back.
In the very bottom of the oven you will see a verticle aluminum heat shield with a screw on one end.
Remove the screw and the heat shield should slide to the right and come out. Set it aside.
Next you will see a little "D" shaped access cover on the back wall held on by a screw with wires coming out. Remove it and set it aside.
Pull out wires going to the igniter carefully until you see the white plastic plug. Carefully get the plug out of the hole. The plastic may be brittle from the heat- BE CAREFUL. Also I noticed a couple of reviews where it looks like people didn't pull out the wires to get to the plug and just cut them. The plug is in there.....
Grab the plug by the two little latches on the sides and pull it apart.
Next, take the nut driver and remove the glow bar igniter off of the burner bar by taking out the two screws.
On my oven the plug did not fit between the burner bar and the back of the oven, so I removed the two screws holding the burner hood to the back wall of the oven and slipped the old igniter wires out past the bracket. This is all of the disassembly.
Slip the wires of the new igniter behind the burner hood bracket and plug them in.
Put the two screws back in holding the burner hood to the back wall.
Screw the igniter to the burner bar, it has four holes. It should be the holes that mount it closest to the burner bar.
Feed the plug and all the excess wire back through the hole in the back wall. Make sure the wires aren't touching the burner bar.
Reinstall the "D" shaped cover.
Reinstall the heat shield.
Plug in the oven.
Turn the gas valve on.
Turn on the oven, stand to the side and back a ways... safety first.
After 3-5 seconds the bar should beging to glow bright orange, then the gas will come on and light.
If it's working turn it off and replace the baking shield and it's two screws.
Done... Good luck!
