The GE Auxiliary Drive Interface Control Board DS3800DDIB1B1C features 8 trimmer resistors and 2 jumpers. The GE Auxiliary Drive Interface Control Board DS3800DDIB1B1C also is populated with 9 test points and 12 resistors. The resistors that populate the board are permanently embedded on the board and are assigned IDs. The ID have a suffix of R followed by a numerical value. Some samples are R1, R2, and R3. The resistors are each part of a circuit on the board.
The troubleshooting opportunities of the board are limited to using the test points. The IDs of the tests points begin with TP which is followed with a number. Together, the suffix and the number create a unique ID. Some examples are TP3, TP4, and TP5. There are several ways to learn what circuits each test point is associated with and what the results of testing represent. However, the easy source of information is to use the printed manual that is shipped with the board. It describes how to install the board, as well as how to use the test points. It also provides information on the warranty and other important information.
Limit the use of the test points to those who are qualified to using a tester device and have a basic knowledge of the board and the drive it is installed in. The results of the testing might indicate that the board an be repaired. However, you must have a spare board available to install in the drive or the drive will be idle during the repair.
