Hello,

Newbie here. I bought a Vendorlator VM126B machine for the garage, plugged it in, it started right up and started to get cold.

Being excited, I went out and filled it with various drinks and waited a day to let them get nice and cold. I noticed the next day that, while the bottom 5 rows were nice and cold, the higher I went up, the warmer my drinks became.

I haven't touched any dials or knobs, as I'm completely new to this game and was told the machine was plug in and go (which it is for the bottom half).

Any suggestions?

check to make sure you evaporator fan is running & circulating the cold air inside...

Evap. fan seems to be running, but the cold air seems to only circulate half way up...need a new fan?

Assuming that there isn't anything blocking the airflow, ( plugged/crushed evaporator fins, ice buildup on the evaporator, etc.) then I'd check to see if it still has it's original electric fan-motor, ( called a unit-bearing motor) it should be listed at 1550 RPM/CW (CW= Clock-wise rotation as viewed from the wire lead end [back of the motor] )& 9-14 watts.

( Fun fact...the higher the wattage the more torque the motor will supply to turn larger diameter fanblades) as an example, you'd never want to use a 4-watt unit-bearing motor to turn a 12" diameter fan, this would require at least a 9-watt motor), also sometimes people use the cheapest unit bearing motor they can buy typically a 4-watt/1550 RPM unit-bearing motor discover that it has the wrong rotation, then they try to mount the fan-blade assemble on backwards to correct the airflow, but it will only cause the fan-blades to "bat" the air around at a severely reduced rate of flow...

Or it could be that the motors just plain old & the bearings are getting sticky & dragging , reducing the motors RPM speed ( RPM= rotations-per-minute for all you newbee's)
