Chaundel-
Welcome to AW.org. You will find a great group of people here that are willing to help new members. If you could post the entire model# and serial# from the mfg. tag that you had in pic #4 there will probably be someone here to help you with the answer. It's a little difficult to make it out in the picture. Just be patient.
It looks like you picked up a nice frig especially for that price.
Again welcome!
