The invention provides a fault detection device and method for a door interlock circuit/a safety circuit of an elevator. The device comprises a voltage measurer, an alarm device and an operation panel, which are respectively connected with a controller, wherein the voltage measurer is provided with terminals A, B and C; the terminal A is connected to a node between a power supply and the safety circuit, the terminal B is connected to a node between the safety circuit and the door interlock circuit, and the terminal C is connected to a node between the door interlock circuit and a door interlock circuit contactor. The device judges whether the door interlock circuit/the safety circuit of the elevator works in a safety range or not by judging the size of the voltage value of the door interlock circuit/the safety circuit of the elevator, carries out early warning for the potential and gradually-changed problems of the door interlock circuit/the safety circuit of the elevator according to the variation trend of the voltage value, and carries out reminding before a fault occurs, therefore playing a role of prevention. When the voltage value of the door interlock circuit/the safety circuit of the elevator approaches or exceeds a preset safety value, the device gives an alarm and reminds maintenance personnel of maintenance.
