Replace the Gear Motor
1. Disconnect the two motor power wires from the motor—note that the black wire is placed in the bottom position.
2. Remove the compartment plate screw.
3. Slide the compartment plate away from the gear motor and the control valve frame.
4. Disconnect the position sensor from the gearbox.
5. Remove the motor retainer rod by squeezing the snap release end of the rod. See Figure 57.
6. Firmly pull the motor straight outward. It may be necessary to tap on the motor body to get the motor to release.
7. In order to insert the new motor into the gearbox, it is necessary to get the "flat" on the motor shaft to line up
with the "flat" in the gearbox drive-gear. The easiest way to do this is to hold the motor in position, attempting
to push it into the drive gear, while causing the motor shaft to turn by using the Advanced Setup\Diagnostics\
Manual Motor Control menu. (Alternatively, if you remove water pressure from the valve, and/or remove the
gearbox from the valve body, you can turn insert a large screw driver into the drive gear and use the screw-
driver to rotate the drive gear so that the flat on the drive gear lines up with the flat on the motor shaft.)
8. Once the motor is fully inserted, re-install the motor retainer rod, compartment plate, and motor wire harness.

Do not touch any surfaces of the circuit board. Electrical static discharges may cause
damage to the board. Handle the AccuSoft™ circuit board by holding only the edges
of the circuit board. Keep replacement boards in their special anti-static bags until
ready for use. Mishandling of the circuit board will void the warranty.
Properly connect the wire connectors to the circuit board. The wires must exit the
plug-in connector opposite of the raised white base of the circuit board connector.
Take extra care when connecting the 24V power. Failure to connect properly will result
in damage to the circuit board.
