Why would this happen? Should I try replacing the wire nut and turning it back on or is there something deeper going on? Thanks for any tips!

The rust and/or bad connection will create resistance at the connection, which can cause it to heat up as well. If that's what happened, it could have melted the wire nut slowly till the wire was exposed, and shorted against a metal part. It looks like there is a diagram of the wiring too to the left near that connection too, which may help if you need to disconnect/reconnect it.
