I just got home from working on a Scottsman Ice Machine Model # CME 1356RS-32D When I arrive all 5 evap panels were frozen solid with ice build up panel to panel. After putting the unit into harvest a dozen times and pouring hot water to thaw the ice I was able to put the unit into a freee mode. Once it went through a cycle the cubes it harvested were normal good size cubes.
I checked the pressures they seemed alright, maybe a little ow but nothing that the tx and hot gas can't over come. The water float was replaced about six months ago, all other components seem to be functioning.
Another tech was there Sunday afternoon for the same problem he cleaned the unit and left. Not to sure what i should start with. I am starting to wonder if it is an intermittant issue with the board not opening the hot gas bypass.
Any thoughts??? I dont have a ton of experiance working on these.
