The present disclosure suggests a dryer and method of controlling the same. Disclosed is a dryer, comprising: a heater for heating the air which is to be directed to a dry drum; a motor for rotating the dry drum; a power supply unit for supplying electric current to the heater and the motor; a heater relay for selectively applying electric current to the heater; a motor relay for selectively applying electric current to the motor; a safety relay for selectively applying electric current from the power supply unit to the respective relay; and a control unit for cutting off electric current by turning off the safety relay when an abnormal stop occurs, after the control unit determines whether the abnormal stop occurs during a drying operation.
