Narrative:

Upon departure; aircraft did not seem to pressurize. After noting this we received an auto fail light on the pressurization panel. We proceeded to run the QRH and asked ATC for vectors and stay at 10;000 ft. Once we were directed to place the pressurization switch in standby mode we noted this did not fix the problem. I tried to ACARS dispatch and contact mx control on the radio with no luck. I decided to return to XXX for landing; as the aircraft would not pressurize. No emergency was declared. Upon extending the gear we noted a loud noise in the flight deck along with a vibration. Once we landed and returned to the gate I went out to check the east and east door and found that it was left open. There was no indication in the cockpit this door was open and the light pressed to test and checked normal. Maintenance met the aircraft and noted the same things and deferred the east and east door sensor. Double-check with first officer that he was able to complete thorough preflight (with de-ice truck spraying the aircraft) during walkaround. Pay better attention when crew member is not familiar with the aircraft.
