Roof a/c froze into a block of ice overnight.
I had the thermostat set so it wouldn't get too cold in here, like I always do. Had it set to "low cool." Woke to a/c sounding very bad. Shut it off, opened the hatch inside the coach and found the co...

To thaw turn AC fan on high. Plenum divider is taped, duct or foil section which separates the intake air from the output air. If it leaks, it recirculates cold air-causing evaporator to run too cold.
But often these icing conditions are just what you describe. It works perfectly most of the time, then one scenario of usage sets off the icing. The evaporator coils on these AC units are on the ragged edge of being too small-and running too cold. For packaging purposes. Speeding up the fan raises evaporator temperature and lowers risk of icing.
