Narrative:

At approximately 3;000 MSL in the climb the flight attendant called to report the main door didn't appear to be fully sealed and that she could see the ground through the space between the air stair door and the fuselage. She also stated that there was a loud noise coming from that same area of the door and she could barely hear me over the interphone. The aircraft was pressurizing normally. We decided to return to the field. During configuration for landing we noticed the flaps did not extend. The first officer was pilot flying and he called for and executed a go around. After the aircraft was cleaned up we checked advisory lights and hydraulic pressures and quantities; all of which were normal. Upon inspection of the circuit breakers we found the L7/flap cont circuit breaker popped. We ran the zero flap landing checklist; advised ATC that we were declaring an emergency and then switched flying pilots so that I could perform the landing. We landed without incident and taxied back to the gate.
