I have had the koolatron vending machine for a couple of months.
While running, it started making a loud sound, now no sound and it doesn't get cold inside. The greenlight comes on, and that's it.
Please help, I really like this little machine.
No sound means the fan has stopped working.
There are many fan alternatives, but it will be necessary to disassemble the unit to get to the original. Have someone trained in electromechanical assembly do this if you do not have the experience.

Sounds like the timmer has not passed the defrost cycle, if you look near the compressor unit, you will see a box with wires going into it from compressor and up into the unit, you should see a small dial about 10-15mm diam, turn this dial clockwise, may need a screw driver, should work once turned, If you cant locate it near the compressor, have a look within the unit or ontop for the timer unit with the dial and tun it clockwise, if the unit operates, spray with a good quality lub spray and turn it fully for 5 revs. Should work fine once done....Russ
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.
Check the condensor fan behind the fridge which is designed to cool the compressor/gas line by blowing air over the condensor. When this fan motor seizes or stops running, the gas gets very hot and because it is skin cooled too, the outside of the fridge also gets very hot. You can overcome the problem temporarily by putting a standing fan behind the fridge, blowing onto the compressor and under the fridge untill you can have the problem rectified.
