Mechanical linkage
DC motor assembly
Check the DC motor cable connector to be sure it is correctly
installed at J2 on the control board. If correct, disconnect J2 from the
control board and check the resistance of the motor on the cable
connector. J2-1 to J2-2 measures between 115 and 135 ohms. Also
check J2-1 and J2-4 to the motor case for shorts. If either the
resistance is incorrect or a short is found, replace the mechanical
linkage/DC motor assembly.
Note: If the DC motor is shorted, it may also be necessary to replace
the control board.
2
Control board
Disconnect the motor cable J2 from the control board and check the
voltages at J2 on the board.
Warning: Use caution not to short adjacent pins on the connector as
damage to the board could result.
If any of the voltages are incorrect, replace the control board. If
correct, replace the mechanical linkage/ DC motor assembly.
