ac froze up when fan on low speed.
Exactly twice my a/c has frozen up.Once last year and just this weekend. Both times it was very hot and humid and the unit ran all day trying to keep up and at some point the fan speed was set to low...

Does it have a wall thermostat? If so it should have a freeze sensor. Sensor is accessed from the inside and often falls away from the evaporator rendering it useless. Or was poorly placed during OEM install.
Also check the air plenum inside. Often the IN is not well separated from the OUT causing cold air to recirculate and over chill through the evaporator.
