Replaced upper interlock door switch and fuse. The trickiest and most time consuming part is disconnecting and reconnecting the various connectors from the control board, and removing the plastic cover to access the upper support interlock. I found it helpful to take pictures with my phone to record the connections. The switch to the left of the upper interlock support was literally fried, and the fuse blown. Entire repair process for me took a little less than two hours, but overall still worth the effort.
