  If the fans in your Hussmann Cooling boxes aren't working, there could be several reasons. First, check the wiring to ensure the unit is properly connected. If the wiring is correct, the motor might be defective and need replacement. Another possibility is a defective defrost timer, termination thermostat, or fan delay switch, in which case you should replace the faulty component. Also, if the room temperature is too high for the fan delay switch, try jumpering the fan delay switch terminals F to B.

  Ice forming on the ceiling of your Hussmann Cooling boxes can occur for a couple of reasons. One reason is that there are too many defrost cycles happening each day. To address this, observe the frost buildup on the coil and adjust the timer to reduce the number of defrost cycles per day. Another cause could be a defective termination thermostat or defrost timer, which would require replacing the defective component.

  Excessive frost buildup on the coil in your Hussmann Cooling boxes can be due to a few reasons. It could be that there are too few defrost times, in which case you should add more defrost cycles to the timer. Alternatively, the defrost cycle might be too short, so you should extend the defrost time on the timer. Also, high humidity in the cooler can cause this issue; try to limit access to the cooler and avoid propping doors open during stocking.
