Did Archer cause the elevator to break?

According to the Archer Wikia it was both Archer and Ray's fault (emphasis mine):

Suddenly, (Archer) shows up and calls for Ray to hold the door. Ray, pretending to press the "door open" button, repeatedly presses the "door close" button, but Archer forces the doors back with a mop. The group begins chatting, then bickering, then shouting, all the while unaware that, through a combination of Ray and Archer's actions, the elevator has malfunctioned until it overshoots the top floor, crashes into the car lift, and stalls.

Archer always seems to be the "Go-To" when anything bad has happened, mainly cause it's usually his fault. So chances are good Archer did cause the elevator to break.

I don't think that was why everyone was angry at Archer. Not to say that he did/didn't break the elevator, but I think what everyone was angry at him for was for breaking the elevator phone somehow by routing Mallory's incoming number to it, which meant they couldn't contact anyone for help, since 911 considered it not to be an emergency.

As for why he did this, it wasn't clear. I would have sworn that in a different episode, he mentioned that he had done so for one of his voicemail pranks, but I haven't found it yet.

I believe it was left intentionally vague.

We know Archer likes to rig phones in terrible ways (remember the mansion when he rigged all the lights and everything and even Kreiger was amazed). That said, he may have just rigged the phone as part of another joke.

The ending implies Malory may have done it on purpose as a "team building exercise", but she claimed they were going to watch Vision Quest.

It's like the ending of season 5, we don't know for sure if it was Malory or Archer.

There's a frequency in the show of the elevator being broken. It was said that they slammed into the motor at the top and thats what caused the malfunction. They attacked Archer because thanks to another of his pranks they had no way of getting out.
