A DC9 failed to pressurize during initial climb. The flight crew was unable to overcome the equipment problem or the associated noise, so they returned to land. Maintenance inspection revealed an unsecured electrical and electronic compartment panel and a faulty compartment door warning contact. Return land.

Narrative:
On preflight the electrical and electronic compartment door was closed. On takeoff, after the gear came up, we couldn't pressurize the aircraft and we tried everything we could think of, but we couldn't pressurize and the associated noise didn't go away. After return to st louis the mechanics at the gate told us the electrical and electronic compartment door was open. Our cockpit light pressed to test, as in our preflight, but didn't show an open door at all. The mechanics shut the door, signed off the light (contact) and we took off. The rest of the flight was normal.

Title: A DC9 FAILED TO PRESSURIZE DURING INITIAL CLB. THE FLC WAS UNABLE TO OVERCOME THE EQUIP PROB OR THE ASSOCIATED NOISE, SO THEY RETURNED TO LAND. MAINT INSPECTION REVEALED AN UNSECURED ELECTRICAL AND ELECTRONIC COMPARTMENT PANEL AND A FAULTY COMPARTMENT DOOR WARNING CONTACT. RETURN LAND.
Narrative: ON PREFLT THE ELECTRICAL AND ELECTRONIC COMPARTMENT DOOR WAS CLOSED. ON TKOF, AFTER THE GEAR CAME UP, WE COULDN'T PRESSURIZE THE ACFT AND WE TRIED EVERYTHING WE COULD THINK OF, BUT WE COULDN'T PRESSURIZE AND THE ASSOCIATED NOISE DIDN'T GO AWAY. AFTER RETURN TO ST LOUIS THE MECHS AT THE GATE TOLD US THE ELECTRICAL AND ELECTRONIC COMPARTMENT DOOR WAS OPEN.
