When trouble shooting the problem I found that the light switch housing outer lip was broken allowing the switch to push through mounting surface behind the oven door. This is a slide in range so, I proceeded to pull the range away from the counter where I could unplug the power cord. Once the power was off like located the panel on the right upper side of the unit and removed the screws to allow access to the switch. I then unplugged the switch from the wiring harness and removed the damaged part. Located part number on switch, logged onto Appliance Pros.com and easily located the replacement unit by following the online instructions. Ordered part which arrived very timely and affordable. Replaced new switch by reversing the steps from taking out and finished the task easily. Than you Appliance Pros. Ease of locating, verifying, ordering and saving money for costly repairs. 5 stars to you! Robert S. Illinois
