About the DS3800NFCD1N1E
The GE Firing Circuit Board DS3800NFCD1N1E features 1 hole in each corner for attaching with screws the board to the drive interior. The board is populated with 4 standoffs for attaching a daughter card. The daughter card provides additional processing, connectors, and features. The board is populated with multiple transistor-transistor logic devices. The GE Firing Circuit Board DS3800NFCD1N1E is also populated with 13 red indicator LEDs and 1 amber indicator LED. The board also has 1 socket for electrically erasable programmable read-only memory (EEPROM) modules. The board is also populated with multiple jumpers and 2 34-pin connectors.
The GE Firing Circuit Board DS3800NFCD1N1E is also populated with test points. A trained servicer with the proper equipment can use the test points to test the circuits on the board. The use of a testing device is necessary. The testing device must be configured for the purpose. Also, the probes attached to the device must be compatible with the device. They must also be in good working condition and free of worn insulation.
The test points all have IDs assigned to them. The IDs are prefixed by TP which is followed by a number. TP21, TP22, and TP23 are all examples of ID assigned to the test points. The service information provided with the board describes the use of the test points. Only test the board when the board is removed from the drive. The board must be removed from voltage and positioned on a flat, sturdy, and clean surface. Use 2 hands to carry the board and refrain from touching the components.
