Center Burner would not ignite via the control knob

Turned off the power to the unit and removed the 2 front screws on the stop-top which are underneath the front when you open the oven door. Removed the back cover and removed the 2 screws for the back of the stovetop and removed the top. Took the old igniter switches out and replaced them with the new set. The connections are simple as they are snap in no wiring required. Replace stovetop screws and replace the back cover.
