Arrived at location on 8/5/22 - Found unit evaporator frosted up. Drawer dividing bar was missing the front piece that gives proper contact with the door gaskets. Flipped drawer dividing bar the other way around so there would be contact with gaskets. Melted all ice from evaporator and made sure there were no more air gaps. Units condenser was very dirty. Cleaned with brush and with viper coil cleaner. Unit is running properly at this time.
