Located ice machine and observed it cycle through the ice making process. Discovered upon arrival though, evaporator iced up, encased in thick ice. Ice cubes backed up from deflector up to top of evaporator and froze over. After observing a cycle and confirming I.M. harvest, melted ice off evaporator. Chemically cleaned plugged condenser coil. Inspected water inlet solenoid and cleaned float switch. MOD states ice machine was cleaned by staff a few days ago. Found thermostatic bin control installed incorrectly. Was told that bin control had slipped off during cleaning and was reinstalled. This may have caused ice to back up over up to evaporator and freeze back a few nights ago. Watched make 3 good batches of ice. Tested voltage at water valve during each harvest and confirmed both it and hot gas valve are working. Unit currently operational. Call complete.
Picked up parts. Arrived on site. Began part install and will return when rest of parts have arrived to install.
