Narrative: Aircraft had a MEL of the left ram air fan. As final gate departure preparation occurred aircraft became extremely hot both on the interior and within the systems. System temperatures exceeded limits to continue and we had to stop the operation in order to lower the temperature of the aircrafts electrical systems. Additionally; cabin temperatures became extremely hot to the point that passenger safety was at risk. The Captain made the decision that in the interest of safety to the passengers that they should deplane. The Gate Manager tried to override the Captain's decision but passengers [were] already in the process of deplaning. The Captain made the decision that in order to take that aircraft the mechanical problem would have to be repaired. The company made the decision to change aircraft to another jet that was coming in from Europe. We waited for it to arrive and began preflighting the aircraft. On arrival Ground Personnel noticed speed tape around the radome that was peeling back in several places. Maintenance was notified and they began repairs. As the flight was prepared for departure we started approaching our MOT (Maximum Time Off) time. As that time got closer we received the logbook and the door closed 7 minutes prior to our MOT time. At that time; prior to brake release we received a status message of Integrated CLG Recirc Air. This message would have to be addressed by Maintenance and would definitely go beyond our MOT time. We contacted Dispatch and the decision was made to delay the flight until the next morning.At that time the Gate Manager entered the cockpit and began to berate the three of us. He accused us of knowingly and falsely creating mechanical issues and walking out on the flight when we could extend our legality. He threatened us with our jobs because he believed we were recording him. There was no recording going on. Cell phones were being used to check Sabre for flight details and scheduling. Finger pointing; loud language; accusations and threats were all part of this beratement and we all were shocked at the level of unprofessional conduct.




Synopsis: B777 First Officer reported switching aircraft due to maintenance issues and having to cancel the flight altogether due to maintenance delays.
