From the Owner's manual. Hardwiring Requirements (24V and 230V Operation) For 24V models: Connect black and white wires to a dedicated 40Va transformer. (Not Provided.) Notice that it says "to a dedicated 40Va transformer". This means that you'll have to install a 40VA transformer to power the device, not use the transformer in the HVAC unit. ...

The capacitor needs replacement. While it is possible there is a circuitry problem causing the capacitor to overheat (and thus fail like this), it is also possible it was simply time for this electrolytic capacitor to fail while nothing else is wrong. See this photo for a similar failure mode.

You already have a source of cooling: the outside air. The "little demon" you are looking for is a thermostat. A thermostat that controls a window fan. Something like this: http://www.amazon.com/Bionaire-BW2300-Window-Remote-Control/dp/B000065DKJ Install the fan vertically with the upper fan set to blow air out, and the bottom fan set to suck air in. ...

The way evaporative cooling works is that it forces air through moistened pads, evaporating the water and cooling and humidifying the air. The cooled and humidified air is then blown through the house and back outside again, lowering the interior air temperature and producing a cooling breeze as well. If I understand you correctly, you are asking if you ...

Definitely mold. Yes you can clean it off - use a mixture of bleach and water. I would however be concerned with the original cause. If you don't fix this, it will just happen all over again.

I would say look for a loose wire or a wire that is partially bare that is touching metal.check your ground wire and make sure that you have a good connection.

From the picture it looks like this might be a window A/C unit. Do you have the option to recirculate air, or is it always pulling fresh air from outside? If it can't recirculate, I doubt the AC unit will ever be able to dehumidify the air. As a workaround, you might want to look into installing a dedicate dehumidifier. This will not pull in any outside ...

UPDATED (not enough reputation to comment, so editing this answer): Another interesting thread here: http://www.greenbuildingtalk.com/Forums/tabid/53/aff/13/aft/77152/afv/topic/Default.aspx Synopsis: if the chilled water is not cold enough, the fan coil unit will not remove enough moisture from the incoming air and RH could rise to mold inducing levels. ...

This is not normal. When the thermostat energizes the G terminal, only the blower fan should come on. Check for a jumper/short between Y and G either at the thermostat, or the air handler.
