Narrative:

Initially, an aircraft behind us reported a panel door at the rear of aircraft was open. Tower had us cross the approach end of runway 4, pull up to taxiway D and hold. While the captain was taxiing, I was in contact with operations advising them of the situation. Maintenance finally arrived after some 15 mins and closed the door then gave us the thumbs up. I then called operations to ask which door had been left open. Before I finished speaking with operations, ground control gave us taxi instructions which I repeated. The instructions were 'taxi aa, F, bb, runway 4.' we were on the west side of the airport which I'd never been. We both thought bb was actually taxiway B, so we taxied up to taxiway F. We knew there were other aircraft in line for departure so he turned on taxiway F (toward runway 4) till I said, 'we have traffic on the runway.' never had we any intention of crossing runway 4. As we came to a stop, ground control stated 'air carrier, stop.' after speaking with the head controller he said the trainee controller got excited when we turned toward the active runway. I would have done the same had I been in his position. Many times as an first officer, I don't have time to confirm where we're going, so maybe if the controller had said something to the effect 'aa, left turn on taxiway F then west to bb, hold short of runway 4.' and we should have verified the taxi instructions had we any doubt. Another factor that obviously played a part, was that now we were looking at trying to catch up the lost time. No one had a close connect at the other end, we were just trying to made departure on time.

Title: MLG FLC INTERRUPTED DUE TO AN OPEN PANEL DOOR IS THEN CLRED FOR TAXI BUT USES WRONG TXWY. THEY STOP PRIOR TO RWY ENTRY BUT TRAINEE CTLR, NOT SURE IF THEY ARE GOING TO STOP, GIVES STOP INSTRUCTION LOUD AND CLR.

Narrative: INITIALLY, AN ACFT BEHIND US RPTED A PANEL DOOR AT THE REAR OF ACFT WAS OPEN. TWR HAD US CROSS THE APCH END OF RWY 4, PULL UP TO TXWY D AND HOLD. WHILE THE CAPT WAS TAXIING, I WAS IN CONTACT WITH OPS ADVISING THEM OF THE SIT. MAINT FINALLY ARRIVED AFTER SOME 15 MINS AND CLOSED THE DOOR THEN GAVE US THE THUMBS UP. I THEN CALLED OPS TO ASK WHICH DOOR HAD BEEN LEFT OPEN. BEFORE I FINISHED SPEAKING WITH OPS, GND CTL GAVE US TAXI INSTRUCTIONS WHICH I REPEATED. THE INSTRUCTIONS WERE 'TAXI AA, F, BB, RWY 4.' WE WERE ON THE W SIDE OF THE ARPT WHICH I'D NEVER BEEN. WE BOTH THOUGHT BB WAS ACTUALLY TXWY B, SO WE TAXIED UP TO TXWY F. WE KNEW THERE WERE OTHER ACFT IN LINE FOR DEP SO HE TURNED ON TXWY F (TOWARD RWY 4) TILL I SAID, 'WE HAVE TFC ON THE RWY.' NEVER HAD WE ANY INTENTION OF XING RWY 4. AS WE CAME TO A STOP, GND CTL STATED 'ACR, STOP.' AFTER SPEAKING WITH THE HEAD CTLR HE SAID THE TRAINEE CTLR GOT EXCITED WHEN WE TURNED TOWARD THE ACTIVE RWY. I WOULD HAVE DONE THE SAME HAD I BEEN IN HIS POS. MANY TIMES AS AN FO, I DON'T HAVE TIME TO CONFIRM WHERE WE'RE GOING, SO MAYBE IF THE CTLR HAD SAID SOMETHING TO THE EFFECT 'AA, L TURN ON TXWY F THEN W TO BB, HOLD SHORT OF RWY 4.' AND WE SHOULD HAVE VERIFIED THE TAXI INSTRUCTIONS HAD WE ANY DOUBT. ANOTHER FACTOR THAT OBVIOUSLY PLAYED A PART, WAS THAT NOW WE WERE LOOKING AT TRYING TO CATCH UP THE LOST TIME. NO ONE HAD A CLOSE CONNECT AT THE OTHER END, WE WERE JUST TRYING TO MADE DEP ON TIME.
