Refrigeration fan that turns on and off to keep unit cold, runs constantly. This is for the Koolatron Vending Machine fridge; model ec-23.
Only the fan at the compressor turns on and off with the compressor cycle. The evaporator fan runs steady to maintain air circulation and temperature balance and to affect evaporator defrost in the off cycle. Sometimes the condenser fan will run continuously to assist in the evaporation of condensed moisture from the evaporator drainage.
The Koolatron Vending Machine EC-23 does not have a compressor like a traditional refrigerator, it's a "thermoelectric" cooler, using the "Peltier" effect.
The effect is the result of DC electrical current passing through wire snaked inside a compound and sandwiched between two metal plates. Heat is drawn to one plate which causes the other plate to absorb heat (it feels cooler). The effect is limited partially by the ambient temperature, and as far as I know this model has no inside temperature control, it uses a it uses a huge aluminum heat sink plus fan on the back to remove heat from the warm side.
To use the machine means you'll have fan noise, and because I doubt the fan uses anything more than a "sleeve" bearing, over time the fan noise will grow as the bearing wears down. Eventually the fan will need to be maintained or replaced.
My evapaorator fan does not run on Genesis Vending maching at all? I am trying to figure it out, what can be wrong? Why it's not running? my compressor fan is running and cycle and turn off... (work fines), just my evaporator fan doesn't run?

No compressor in EC-23. Constant fan noise is normal.
Azkoyen fan 330 vending machine has ''out'' on the display and I can not find out what this means,
