Motors and Harnesses
1. Check for proper connections between the motors and harnesses (Fig. 17).
2. Visually inspect the exposed harnesses to ensure they are not pinched or damaged.
NOTE: Ribs on motor connector line up with notch inside of female connector on wiring harness. Color
codes on wires also match (black to black, red to red, etc.)
Resynchronizing the Slide-out Motors
1. Fully extend the slide room using the switch. Keep the switch engaged until the motors shut down on
their own.
2. Retract the room 1-2 inches.
3. Repeat steps 1 and 2 until both motors shut down at the same time. In many cases, two or three
repetitions are necessary to re-sync the system.
4. Fully extend the slide-out and keep the switch engaged until the motors shut down on their own.
Fully retract the slide-out, again keeping the switch engaged until the motors shut down on their own.
If both motors shut down at the same time at full extension and full retraction, the room is properly
synchronized. If they do not shut down at the same time, repeat the process until they do.
Extend and Retract Switch Connections
Rev. A - Rev. C1 Controllers: Common connection on controller goes to common connection on extend and retract
switch.
Rev. C2 and 8 amp Controllers: Extend and retract connections on the controller go to the extend and retract
terminals on the switch. Switch is powered by the OEM supplied 12V DC power source.
Power and Ground Connections at the Controller
Power and ground are supplied to the controller through the spade terminals located on the right-hand side
of the controller (Figs. 2 and 5 - Power Connection). 12V DC is recommended. A 10ga wire is the minimum size
recommended. A 30 amp resetting or blade fuse is required (OEM supplied).

Visual Inspections
Measurements
1. Measure from the outside edge of the column to the face of the gear rack (Fig. 18 and 19). The
standard measurement should be 2 ½" plus or minus ⁄". Take this measurement when the room is
fully extended and again when the room is 3" from fully retracted.
NOTE: For units with non-standard installations, contact the OEM for their specific measurements.
2. Measure the gear racks for parallel. There should be less than ⁄" difference between the parallel
measurements.
3. Check for proper seal engagement (no binding, ¼" nominal overlap).
4. Check for damage to gear rack.

Troubleshooting
Checking Circuit Breakers
The IN-WALL® Slide-out requires a minimum of a 30-amp circuit breaker. Check the 12-volt circuit breaker box for
blown circuit breakers, and replace any if necessary. Consult the RV manufacturer's documentation for the location
of the 12-volt circuit breaker box, and the location of the IN-WALL® Slide-out controller’s circuit breaker. If the
circuit breaker blows immediately upon replacement, there is a problem with the wiring to the IN-WALL® Slide-out
controller. Have qualified service personnel check and repair.
Obstructions
Check outside the RV for possible obstructions: tree, post, car, etc. Check inside the RV for any obstructions:
luggage, furniture, open cabinets, etc. Also, check for smaller objects that may be wedged under the floor or in the
sides of unit. Remove obstructions before proceeding.
Debris in the rack
Check the sides of the slide room for any dirt or debris. Small dirt clumps or metal shavingscan cause the spur gear
to bind up and stop the movement of the slide-out. Usecompressed air or a dry brush to remove any dirt or debris
from the rack beforeattempting to actuate the system again.
Error Codes
During operation when an error occurs, the board will use the LEDs to indicate where the problem exists (Fig. 22).
For motor-specific faults the green LED will blink 1 time for motor 1, and 2 times for motor 2. The red LED will blink
from 2 to 9 times depending on the error code (Fig. 23).
When an error code is present, the board needs to be reset. Energizing the extend/retract switch (Fig. 1) resets the
board. Energize the extend/retract switch again for normal operation.

Electronic Manual Override (Controllers C-1 and C-2 Only)
NOTE: See (Fig. 24) for locations of the mode button and LEDs.
1. Press the mode button on the controller six times and hold on the seventh for five seconds to enter
electronic manual override mode.
2. Use the extend/retract switch to move both motors in or out.
NOTE: Over-current and short circuit detection are still enabled. Electronic manual override provides 12V
directly to both motors.
3. To exit the mode, push and hold the mode button until the LEDs begin to blink simultaneously. Exiting
the override mode resets the motor positions (you will have to resync motors).
NOTE: During this override procedure the motors are not synchronized. Visually watch the room: if one
side is moving significantly slower than the other (or not at all) then immediately stop and use the
"Motor Disengagement Procedure" below.
Motor Disengagement Procedure
1. Remove motor retention screws located near the top of each vertical column on the outside of the
coach (under bulb seal if equipped with bulb seal on column).
2. Locate motor.
A. On units built prior to 2011: Bend back wipe seal from outside of coach.
B. On units from 2011 to current: See slot in H-column on the inside of the coach.
3. Pull motor up until disengaged (roughly ½"). A flat-head screwdriver can be used to pry the motor up.
4. Reinstall motor retention screw to hold motor in place or remove motor.
Low Voltage
The Lippert IN-WALL® Slide-out Controller is capable of operating the room with as little as 8 volts. But at these
lower voltages the amperage requirement is greater. Check voltage at the controller, see Figs. 2 and 5 for the
location of power connections. If the battery is low, it needs to be charged or the unit should be plugged into shore
power or the generator can be run, if equipped. It may be possible to "jump" the RV's battery temporarily to extend
or retract the room. Consult the RV manufacturer's owners manual.
NOTE: Always connect directly to the battery and never to the controller power connections.
Motor Direction Switches
Motor direction switches (Fig. 24) are used to change the direction of individual motors. If when trying to extend
or retract the room, one side goes in and the other side goes out, then there is a problem in the wiring. The motor
direction switches can be used to correct this problem. The left switch controls motor 2 and the right switch
controls motor 1. If motor 1 is going in the wrong direction then change switch 1’s position. If motor 2 is going in
the wrong direction then change switch 2’s position.
The motor direction switches can also be used to change the direction of the extend/retract switch. If the room
extends when the extend/retract switch is moved to the retract position, its direction can be reversed by moving
both switch 1 and switch 2 to their opposite positions. This feature can be used if it is more convenient to change
the motor direction switches than to rewire the extend/retract switch.

Rewiring Instructions
If it is necessary to replace a malfunctioning Rev. B, C, or C1 controller, it is recommended that the customer
do so with a new Rev. C2 controller. In order to properly rewire a Rev. B, C, or C1 controller to a new Rev. C2
controller, the customer will need two new motor harnesses (one for each motor.) Additionally, it will be
necessary to modify the power wire from the controller to the extend/retract switch by adapting the wire to
piggyback the connection at the power junction. This wire comes from the positive side of the buss bar to
the controller (Fig. 25).
