We have a 3001w (2014)
Our main(living room) AC didn't work as I thought it should either. The unit had a very large swing of temp (+-4 degrees) between the time it would come on and when it would shut off. The FAN setting would not run just the fan at all either. The added AC in the bedroom has a digital thermostat which works great. I picked up a digital for the main and now it works perfect with a 1 degree swing fom the set temp. I have found the difference between fan speeds is very little, so you may have to listen closely.

"Happiness? A good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle."
