PURPOSE: A ductless dryer is provided to accurately detect malfunction of the ductless dryer by separating a ground of a main body from grounds of a flame sensor and a control unit. CONSTITUTION: A ductless dryer is composed of a hot air supply unit, a flame sensor(160), a control unit, an isolating unit(190), and a rotary unit(147). The flame sensor senses flame exhausted from the hot air supply unit. The control unit determines whether the dryer is normally operated based on the sensed flame. The isolating unit electrically isolates the hot air supply unit from the flame sensor. The rotary unit mixes gas and air within the hot air supply unit.
