Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. A PTAC controller is operably coupled to a compressor and an indoor fan for performing a cooling cycle. The compressor is stopped after the indoor temperature drops below a target temperature, but the indoor fan continues to circulate air through an indoor portion of the PTAC until a fan stop condition occurs. The fan stop condition occurs when the discharge temperature is at or above the dew point temperature to prevent condensation on components within the indoor portion of the PTAC.
