FAULT DETECTION DEVICE, ELECTRICAL INSTRUMENT AND METHOD FOR FAULT DETECTION

摘要

PURPOSE: A failure detection apparatus, an electronic device, and a failure detection method are provided to easily obtain information for failure load and to reduce time and costs consumed in service. CONSTITUTION: A failure detection apparatus is comprised of interface(200) and terminal(300). The interface is electrically connected to an electronic device and transfers a driving command of one load among a plurality of loads included in the electronic device to the electronic device. The interface detects a current flowing in the load of the electronic device. The terminal receives a current signal flowing in one load from the interface. The terminal determines whether the load breaks down or not based on the current signal.
