時コンプレツサー停止装置。[Claims for Utility Model Registration] (1) Connect the compressor drive relay 24 of the refrigerator to the output port 1-C of the microcomputer 1, and connect it to another output port 1-B of the microcomputer 1 that generates pulses with a constant duty. , when the output of output port 1-B of microcontroller 1 generates a constant duty pulse between reset input port 1-A, no reset is applied,
A compressor stop device when a microcomputer runs out of control is connected to a forced reset means 25 which resets the compressor when its output is fixed at H or L. (2) The compressor stop device in the event of microcomputer runaway according to claim 1, wherein the output port 1-B generates a pulse with a constant on-time.
