PURPOSE: An apparatus for detecting an error of a fuse in a wafer burn-in system is provided to detect automatically error states of fuses installed on plural boards by mounting a fuse error detection circuit within an error detection unit. CONSTITUTION: An apparatus for detecting an error of a fuse in a wafer burn-in system includes a main board(220), an error detection unit(150), and an error display unit(160). A plurality of boards(210-1 to 210-n) are mounted on the main board(220). The main board receives sensing signals from each board(210-1 to 210-n) and outputs a fuse error signal according to fuse errors generated from one or more boards. The error detection unit(150) generates an output signal corresponding to the fuse error signal when the fuse error signal is generated from the main board. The error display unit(160) displays an output signal of a fuse error detection circuit(151) of the error detection unit.
