Sure if it works, it works-and yours may be set up absolutely correctly not to ice up. But be aware the conditions for ice up can be unusual. To be specific, a temperature which is relatively cool but keeps the compressor on for extended times.
Mine will rarely ice up at least partially. When looking into it the anti ice probe was installed in the wrong location on evaporator. These air conditioners, due to compact size and flow patterns do seem to run on the ragged edge of evaporator icing.
Even though yours worked, keep the tips in mind. You may need them someday under an unusual circumstance. If you do experience icing, keep fan speed on high, the filters spotless, and try to set the thermostat set to 72 or more (maybe as high as 75) to cycle the compressor before the ice forms.
It doesn't have a temperature selector just a knob that goes from blue to red. I set it right in the middle maybe a little to the red and the temperature in the trailer was very comfortable. You cannot hear the compressor cycle because the blower sounds like a jet engine especially on the high cool setting which is the max fan setting. It only has two speeds. Fast and semi fast its not really a low speed fan.
