A checking system of an automatic fire extinguisher is provided to enable a user to know a disconnection and opening or closing state of a break part by installing a circuit part for checking the opening or closing state of the break part in a receiving part and making a signal processing part analyze the checked signal. The checking system includes: a detecting part(9) for detecting leakage of gas; a sensing part(10) for sensing a preliminary fire and a fire; a signal processing part(20) having a microcomputer and an IC(integrated circuit) so as to output a high or low opening/closing control signal and IC power control signal according to the sensed signal; a break control part(30) having a motor driving IC(31) driven by the high or low opening/closing control signal; a break part(40) having a first and second stop switch(SW1,SW2) and a motor(41) so as to control an opening or closing operation of a gas valve from the driving; and first and second check circuit parts(50,60) connected parallel with each other for checking an operation status of the break part.
