seems to have decided to switch outlets for condensate drain and is leaking off the roof

anyone else had this happen…not draining at the normal place

Your drain line may be plugged. I had that happen when spiders built a web in the bottom of my drain. One solution is to force air into the bottom of the tube to blow the obstruction out. This however only moves the problem up into the water catchment under the coils and it may clog again later. The drainage you are having is probably overflow from the catchment pan. A better approach is if you have any way to apply a vacuum and draw the blockage out.

As Morgan Guy suggests, an insect of one variety or other may have called your drain tube home. The likely spot will be within a couple inches of the lower end. Depending on how much tube extends out, you could try pinching it with your fingers to see if you can crush the nest within or gently probe from the end with a thin screwdriver or similar but take care not to push anything further in. As suggested a vacuum is best if it can pull something out. If you have success you may experience a brief rush of water as what may be backed up in the tubing let's loose. One thing to consider is local humidity. Low humidity = less condensate.

The cover/cowl on the inside comes off with 4 screws. From there you will see the drain line. Pull it, apply air from the inside blowing outward and if there is a plug in it, that will blow it out the correct end.

Replace hose to unit, put interior cowl back on, and you're back in business.....

Last summer in high humidity when my ac froze up and wouldn't cool, one of the symptoms was that it was no longer draining through the outside hose but dripping water from the unit inside the AS. Not sure if this applies, but it could be that the drain tube could be frozen along with the unit itself.

Turning it off for 30 minutes, letting it thaw and then restarting solved the problem and has made our camping soooooooooooo much more enjoyable.

If that's the case, turning on the heat pump, if so equipped could also defrost it pretty quick.
