Is the drain line heater working and /or drain clear of blockages? If not water will back up into the drain pan. Is the fall correct on the drain line?
Mostly found in Oxfordshire, UK :)

Is there a trap fitted? If not warm air will freeze inside the pipe!

Try some self regulating heat tape like you would use on gutters for a house to keep them from freezing.
