The existing spring broke and ended up on the floor. I did however have to remove the pin (simple--used needle nose pliers) from the door--it was slightly cracked. I purchased a new spring and pin which came extremely fast which I appreciated. I put the pin on one of the ends of the spring, put this in place, and then needed a little elbow grease to get the other end of the spring into the hole in the door. The job took me 5 minutes. I'm not sure what the chime that tells me when the door was left open isn't working but that's OK, the main issue was solved.
