Narrative:

On final to mia runway 12 ILS, gear down got red nose gear unsafe and no green lights for gear. Did fly-by and tower informed us gear appeared down and locked. Told to climb to 3000 ft, switch to departure and turn right 180 degrees. During all of this trying to figure out whether to try to raise gear, setting speed bug, trying to get heading select, first officer talking to department, hand flying and looking at EFIS display (we get to see this once every week or 2), I climbed to 3600 ft or 3700 ft before catching it and descending back to 3000 ft. ATC didn't say anything and we know of no traffic conflict.
