PROBLEM TO BE SOLVED: To provide a diagnostic device for an elevator door, having a means for determining that a door load state is an initial value with respect each of a plurality of sections from a closing end to an opening end of the door to determine which section from the closing end to the opening end of the door causes a door traveling abnormality. SOLUTION: This diagnostic device for the elevator comprises a load detecting device 8 detecting load amount of a drive motor 5 for opening/closing the door 2; a storing device 42 storing a standard value of the door motor load amount in the plurality of sections from the opening end to the closing end of the door 2; a comparing and calculating means 41 calculating the load amount detected by the load detecting device 8 and a deviation value of the standard value stored in the storing device 42; a storing means 92 storing deviation values from the standard values in the plurality of sections from the closing end to the opening end of the door 2 as initial values; and a comparing and determining means 91 determining whether or not the plurality of deviations stored in the storing means 92 exceed a fixed value; and a display device A displaying the determination result of the comparing and determining means 91.
