How to make cans get colder in koolatron vending machine

I got the koolatron model # ec - 23 as a gift and it keeps cans cool but not as cold as if putting them into fridge. I keep it in the entertainment room when people come over to visit. I wanted to find out if there is a way to change it to make the drinks colder.

AS I UNDERSTAND IT, THE LOWEST POSSIBLE SETTING IS ABOUT 40 DEGREES F BELOW AMBIENT TEMPERATURE SO OTHER THAN KEEPING IT OUT OF THE SUN OR A HOT CAR, THERE IS LITTLE YOU CAN DO. THE UNIT USES THE PELTIER EFFECT (THE REVERSE EFFECT OF A THERMOCOUPLE) TO ELECTRICALLY MAKE A COLD AND A HOT JUNCTION. RUNNING ON 12-14 VOLTS DC, IT MAY BE SAFE TO MIST WATER ON THE HOT JUNCTION, OR OTHERWISE COOL IT, TO IMPROVE IT'S HEAT DISSIPATION CAPACITY. I DON'T KNOW, I HAVE NEVER HAD THE OPPORTUNITY TO TRY IT.

Top of the refrigerator is not cooling and the freezer portion is to cold


Main cooling happens in the freezer.

Since top (fridge part) not getting cooling the sensor in that part is continuously asking for cold. So the freezer get colder and colder.

Fridge part not cooling can be due to one of the many reasons.

Evaporator fan, Defrosting problem, Damper motor issues etc etc.

I purchase a koolatron CVF18 Vending Fridge I plug it in and neither the fan nor compressor came on but the power light on the power cord came on


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

Vegetable draw is getting too cold and freezing contents,


Good day,
Seems to be a common complaint when colder weather sets in.

This problem seems more acute when the rooms cool down, and the machine gets light usage.
The main reason, is the machine stays off for longer periods of time and the air stratifies in the fresh food compartment.
That is, the cold air tends to settle to the bottom of the compartment when the machine is off and the circulating fan is not running.
recommendations are to set the thermostat to a warmer setting..
Sounds good, however, there are techs who recommend setting it to a colder setting, to keep the fan running more frequently.

I know it sounds ludicrous, but it's primarily the result of trying to keep one compartment at 0 degrees and another at 37 degrees using only one compressor and one cooling fan.

Many years ago, many refrigerators had 2 fan motors, one for each compartment, and 2 thermostats. These machines never had this problem.

Vending machine issues


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.
