Remove plug in unit from stove top. Turn over and remove the 7 screws from the 4 sides only. Turn back over holding unit together manually. Remove the glass top gently and lay it aside. Remove two wires that are plugged into the old unit, remembering which belongs where. You might want to remove one at a time and connect to new unit. Place new unit in between the three guides. Make sure the other unit is aligned also. Place glass top back unto unit and replace the 7 screws. Put unit back into stove top and test. Finished in less than 15 minutes with no issues.
Loosened 7 hexnuts on the cook top. Removed the glass top and replaced it with the new one from PartSelect. Put the hexnuts back on. Plugged the unit back into the Jenn Air and it worked perfectly. PartSelect was a big help making sure I got the right replacement part which was hard to find. Without them I would not have been able to make the repair.
