I couldn't locate a Manitowoc ice machine with that model or serial number. I looked on their site too, and nothing came up. What I can do, however, is share with you a link to their literature library: http://www.manitowocice.com/minisite/service/servicedownloads. You should be able to locate the parts you need there.
Also, if you want to live chat with us or give us a call at 888-388-6372, we can help track down the part(s) you need!
