have the freon checked

Hi,
Many times this unit seems like it is running just fine, but in fact it has a problem...
Most have a freeze sensor that will shut down the unit if the evaporator coil gets too cold...
Now that problem can be caused by a couple of things...

A dirty filter or evaporator coil...
Low freon charge...in this case you have a leak somewhere in the refrigeration system...
Freeze sensor thermistor (probe) or circuit board are bad....
Fan motor not running full speed.....

These are the most common reasons why your A/C would run for a few minutes and then shut down...

??? an airconditioner making ice??? You sure its not a fridge??

On a portable AC, the only way water can be distributed is by a pump which pumps the water out of the collector tank. Chances are that the impellor inside the pump has stripped or is slipping, therefore not pumping the water. ( that is , I am assuming , this model is an evaporative type cooler?? ) if it is a refrigerated type, there shouldnt be any need for water , however , it will have a condensate pan which catches the water produced by the refrigeration cycle.

Go to your local hardware store, they should be able to help you.

If the drip line is raised too high, sometimes the level inside will exceed the trip-point for the pan-level.

Try lowering the drip line so the water runs 'downhill' the whole way. If it still occurs, the sensor in the pan may be stuck.
