A few weeks after removing the unit and cleaning the coils the Dry mode and Energy Saving mode stopped working. The Cool mode works fine -- the fan and compressor run and cools properly. The Fan Only mode works as well. When on Dry mode or Energy saving mode, the fan does not run and there is a low humming noise. On occasion I can "force" Energy Saving mode to work by first running the AC on Cool mode for awhile then toggling quickly to switch to Energy Saving. I cleaned off the thermistor and that didn't seem to help. Any advice is appreciated!
