Microwave removal from TaB 400

in 2019 it has a plug.

@NoVaGuy pulling the microwave is not going to give you access to the back of the control panel by the door, if that is what you are trying to do.  The upper cabinets have solid sides, top, bottom and back, like a box.

The control panel by the door entry is set into a ply box chase, think hollow wall space.  You can gain access to the lower part under the upper cabinets by removing the small panel on the left side of the sink, where the outlets are.

To get to the back of the control panel, switches, Alde control, etc, you need to remove the switch or Alde panel and pull it out, there is some slack,on the wires to allow them to come out a few inches, to get to the connections behind them.

Here is a shot of the cabinets during construction before the back panel is installed:

You can see the double partition where the control panels are located.  The front section of this section can be removed from the front, screws under the little plastic caps. The back is a solid one piece section that covers the back of galley upper cabinets, which seems to be installed from the open back before the trailer side is installed.
