I suffered the same problem this morning and I am glad I found this site. I couldn’t jimmy the door latches open with cardboard, but a piece from a plastic milk carton was thin and flexible enough, but strong enough to do the job. I took the cover off and located the problem. My little post was still partially attached, so nothing had fallen out and it wasn’t obvious where the issue was. I shut the door and worked the latch and could see the cam mechanism just flexing out of the way. I decided to pull the plastic assembly out of the unit by detaching the wires (take pictures!) and removing two screws. With the piece out I could see that the hole where everyone runs the screw was partially blocked by a small stiffening rib in the casting. I used a Dremel tool to remove just enough of this to allow a machine bolt head to sit perfectly flat. I found that a number 8 machine screw was a perfect fit for the diameter of the hole in the broken peg. I inserted the screw, slipped the peg over it, installed the cam mechanism on the peg followed by a washer and two nuts (jammed against each other to prevent any slippage and with a drop of blue LockTite). Reassembled and I am back in business.
