I just viewed a 2012 video for a Windjammer 3008 without stainless, and yes, there appears to be an access panel below the oven. My unit has a drawer. Hope I can find someone that has the same option. FR must have had to relocate the lines to accomnodate the drawer.
Hope this helps. I think with the drawer under the oven though you may have a little different setup then my model 3008W. (2012 model year) My model has a cabinet type door with a third hinge that you have to unscrew to open the door.
