It took 15 minutes for the wet/dry vacuum to suck out the white slime followed by a hot water wash. White slime forms in dark, cool, damp atmosphere which describes you AC condensate drain system.

I now use the vinegar wash, warm water rinse monthly as per above. So far no more drain issues for about 8 months
.

If your thermostat suddenly goes blank, your condensate line has blocked up and the water sensor in the condensate pan has shutoff the power to the AC unit.
Mine went three years with no flushing before it plugged. I believe it was the white slime but it was very dark when I cleared it to get it running again. Since then I flush it with a gallon of water monthly. Two years and no problems yet.
