The complaint from the customer, who has positioned the unit outside their small motel, is that while the soda seems to be properly cooled during the middle of the day, there are times when the product is warmer than desired. Temperatures during the day are in the mid 70s, while the temperature later in the day drops to the low 40s. When you make your initial stop early in the afternoon, you note that the unit seems to be operating normally with both the evaporator and condenser fan motor running normally. And, when you check the wiring diagram, you note the condenser fan wiring shown in the partial diagram in Figure 2.
