In order to replace the burner you have to remove the top panel which is being held with 12 screws (3 screws around each burner). From my experience, when you try to remove those screws they usually break and a part of a screw remains in the burner body. So it is very possible you'll end up with all four burners needed to be replaced.
To replace the burner itself is not very complicated and with a little technical skills you can do it.
- The part number for the burner is
AP2150401 (they all are the same)
- The part number for the burner cap is
AP2123846
- Here are the break down diagrams for Gibson (made by Frigidaire) range
Model GGF356BAWA
Good luck.
