This window pack is also known as an oven door window pack assembly and is a part for your range. The window pack forms a see-through heat barrier within the oven door glass. Before making any repairs...
First disconnected power to the oven at circuit breaker box. Then, Removed top front control panel, held by four screws exposed when top oven door is opened. Was able to move control up and out of the way without disconnecting. The relay control panel is visible on the right. I was able to reach all connectors with needle nose plie
... Read morers and then remove the panel with needle nose to release clips and use screw driver to gentle pry up. Installed new unit by attaching back connectors and then setting panel down onto clips. Finished with attaching front connectors. Reattach front control panel.
I did not do the repair since the part shipped was not the correct one. I have contacted Customer Service by phone and mail and nothing has been resolved.
I would, at least, like to return the incorrect part. An new one would be great but not holding out hope.
