As far as I know the only thing that HI of LO effects is the speed of the fan. It is like the fan speed in a vehicle, the faster the fan the quicker it should cool as it is moving more air. Coils usually will freeze up for three reasons, either the coil is dirty and it traps moisture which will then freeze, or system is low on refrigerant and that makes it a bit more efficient before it quits. Also there should be a T-stat on the coil that senses the temp there, so it should not freeze up. If your coil freezes up either sensor is out of position, or it is not working right.
Correct to a point. The LO fan speed travels air thru the fins slower and that allows the Evap to get colder and the AIR is colder as it has just a little more time to have the hot air removed and thus freeze IF the unit has no freeze sensor. On HI speed the air flows faster and turns over the hotter air faster to get cold. ONLY wall tstat systems have a freeze sensor. This is why the instructions state to run on hi cool to prevent freeze ups if there is no freeze sensor system. Doug
