Checked online instructions for range top ands rear upright removal. Cleaned inside surfaces before removing individual wires one at a time. Ran the new wires through retainers first, then to the correct igniters next. Replaced removed parts to restore.
Note: The remove the top burner screws from the cook top before trying to remove it. Otherwise, you will bend the burner gas supply tubes and possibly damage them if not done in sequence.
Utube mentioned using a screwdriver for the cook top screws. This was not actually the case with our model. Used Allen wrench to remove and replace them.
The repair experience good, just wish it was not necessary to do. Furry creatures have strange feeding habits and taste bents!
