The invention relates to a lift car (1) having at least one lift door (2), having a door drive (3) for actuating the lift door (2), having a sensor (4) for detecting the motor power of the door drive (3) and having an evaluating unit (5), which determines, based on the motor power detected, whether there is a deviation in the travel profile (6) from a reference travel profile (7). According to the invention, the evaluating unit (5) is designed to determine whether a deviation occurs due to an obstacle in contact with the lift door (2) or due to altered external conditions, particularly due to altered pressure conditions and/or air flow.
