Thanks to the guest user for the heads up on where to find the screws to remove the front panel.

The four out side knobs have one upper screw that is all to remove the panel from the front then the
under side and on the inside of the cook top with the cast iron grids removed. do not forget to unplug the range before starting this. another part is the temprature probe - check to make sure the wire is not inside the oven as it will melt and cause the same problems.
