The GE Power Supply Board DS200EXPSG1 features one reset button, 3 fuses, and 1 LED. The GE Power Supply Board DS200EXPSG1 also is populated with 3 9-pin connectors, multiple capacitors, and test points. The board functions by receiving command signals from other boards. During normal processing the board is able to react to the commands and perform as expected. However, on occasion the commands are in complete or have been interfered with by electrical sources. The board might react by stalling or providing intermittent response to the commands. In that case, a proper first troubleshoot step is to locate the reset button on the board. The reset button causes the processing on the board to restart without powering off the board. If any interference has been received or processing errors exist, pressing the reset button will clear any problems. You can press the reset button while power is being received by the board, however, care must be taken to not touch any components on the board due to the high-voltage current present on the board.
Also, when you reach into the board cabinet, avoiding touching any other boards or components. Serious injury or burns might result from touching components. It is best practice to have another servicer or assistant nearby while the procedure is taking place. If an accident occurs, the other servicer can pull the emergency power shut off device or call for help, if needed. Before reaching into the drive, make sure the floor is dry and free of grease and oil. Any moisture would conduct electricity and lead to a dangerous condition.
