The apparatus increases the reliability of a laundry dryer by measuring current at the assembly line. The apparatus consists of a load driving unit(13) for conrol of several loads; a current transformer(C.T) comprising a transformer, a resistor and a diode, to measure the current of the loads; transistor(Q1) comprising transistor, a capacitor and a resistor, to output steady voltage in a certain duty ratio; an inspection unit(16) for supplying steady voltage to the output part of the transformer; micorprocessor(12) for checking the condtion of the current transformer by measuring the output from the transistor part.
