What you need to do is remove the front control panel in the door.
From memory on these theres 2 small tabs at the bottom and the top is hinged on.
So try and get you fingers or nails under the frame at the bottom and lift up and it should swing out from the bottom and unhook from the top.
This are a bit fidderley to do but it will come off.
Im pretty sure its the bottom which has the tabs but if struggling just try it from the top instead.
Once this is off you need to disconnect the wiring on then board but make a note of which connection on the board it went on as it can fit on both.
Then with that disconnected you can then pull the wiring up through the door from the top hinge and out.
Once you have it out you need to reroute it round the top of the panel so it comes out at the other side were you will swap the hinge to.
Then you can push it down the door again and refit the hinge and door back on.
Then refit the control board and should do it.
Let me know how it goes.
