About this Document
This document is a field troubleshooting guide meant to help end users resolve common issues quickly, and
to help retract the slide for travel if further troubleshooting is required at a service location.
For more detailed troubleshooting, more technical documentation is available at:
https://support.lci1.com/slide-outs-support-slimrack.
Please see the following steps below. These are the most common remedies used to get the RVer back to
camping.
1. The steps to resolve the most common issues are:
A. Inspect for obstructions and damage.
B. Check for low battery voltage.
C. Reset and reprogram.
2. If after following the above steps the slide-out is not fully retracting, override the system:
A. First, perform an electronic override, see page 8.
B. If an electronic override fails to move the slide-out, perform a manual override, see page 9.
Safety
Read and understand all instructions before installing or operating this product. Adhere to all safety labels.
This manual provides troubleshooting procedures. Many variables can change the circumstances of
the service procedure, i.e., the degree of difficulty involved in the service operation and the ability level
of the individual performing the operation. This manual cannot begin to plot out procedures for every
possibility, but will provide the general instructions for effectively servicing the vehicle. In the event the
skill level required is too high or the procedure too difficult, a certified technician should be consulted
before performing the necessary service. Failure to correctly service the vehicle may result in death, injury
or voiding the warranty. The owner's manual for your unit may have more procedures for service and
maintenance.
The Lippert SlimRack Slide-out System is intended for the sole purpose of extending and retracting the
slide-out room. Its function should not be used for any other purpose or reason than to actuate the slide-
out room. To use the system for any reason other than what it is designed for may result in death, serious
injury or damage to the unit.
Before actuating the system, please keep these things in mind:
1. Parking locations should be clear of obstructions that may cause damage when the slide-out room is
actuated.
2. Be sure all persons are clear of the unit prior to the slide-out room actuation.
3. Keep hands and other body parts away from slide-out mechanisms during actuation. Death or serious
injury may result.
4. To optimize slide-out actuation, park unit on solid and level ground.

TROUBLESHOOTING AND REMEDIES
Step One: Inspect For Obstructions And Damage
Obstructions such as rocks and twigs will interfere with slide operation. Check the rails for obstructions and
clear them if present.
Step Two: Check For Low Power
Make sure the battery is fully charged. Even when connected to shore power, it can take a battery time to build
sufficient stored charge to properly operate the slide.
Step Three: Reset Controllers
Performing a Factory Reset and reprogramming the soft stops can facilitate troubleshooting and sometimes
correct the issue. It must also be performed after any mechanical/motor/harness repair.
An underlying fault and/or the repair can make the controller think the motors are at different locations. The
fault condition may cause the auto-program controller to enter a jog mode. The jog mode may interfere with
testing the repair. A Factory Reset exits the mode (as does a power cycle).
Factory Reset - Auto Programmable Controllers
1. Identify Controller and Revision
NOTE: If your controller is not shown in Fig. 2, skip to Factory Reset - Programmable Controllers section.
A. The controller part number can be found in the upper right corner of the label on the front of the
controller (Fig. 2A).

Factory Reset - Programmable Controllers
Factory reset is performed when entering manual programming mode as described in the Setting Soft-stops
section for Manually Programmed Controllers. Use this procedure to initially set the IN and OUT stops or change
the current stop settings.
NOTE: At any time during the program procedure, the unit will exit program mode if the slide-out has not
been moved for two minutes or if a fault is detected during programming. The FAULT CODE and
ROOM OR LOCK MOVEMENT LEDs will flash rapidly for 10 seconds to indicate that the programming
procedure failed. After 10 seconds of flashing, the controller will automatically default to Fault Code
1—Troubleshooting section—and programming must be restarted.
1. If the touch-pad switch (Fig. 8) is mounted to the wall, remove it to access the buttons (Figs. 9 & 10) on

5. Plug Motor 1 harness back into the Motor 1 receptacle and plug motor 2 harness back into the Motor 2
receptacle.

6. Verify that the controller is in Jog Mode: A. Press OUT (Extend) or IN (Retract). The room should only
move for about one second and then stop every time the switch is toggled. This is Jog Mode.

7. Retract the slide fully.

8. To exit Jog Mode, either:

A. Disconnect 12V power from the control by removing the 2-pin battery harness for 5 seconds. After
5 seconds, plug the battery harness back into the control;
Or,

B. Wait for 5 minutes. The control will time out and exit Jog Mode, returning to normal operation
mode.

NOTE: During certain faults, auto programming controllers enter a jog mode automatically. Jog mode
limits the movement of the slide to very short intervals. Repeatedly press and hold retract until the
slide is fully retracted.

NOTE: It will take several attempts. Retract the slide fully for transport to service.

Programmable Controllers

1. After a factory reset and during certain faults, the in and out buttons on the touch pad will only work
if the controller is in programming mode. To enter programming mode, see the Factory Reset -
Programmable Controllers section. Then, retract the slide fully for transport to service.

2. If the controller detects signal issues from the motor, it may stop moving after 1 second of operation.
You will need to repeatedly press and hold retract to completely retract the slide.

When manually retracting the slide-out room, make sure that both sides of the slide-out room move

together. Damage to the slide-out room may result if movement is not uniform.
Manual Override

In the event that power is lost to the slide-out motor(s) or when the Electrical Override Mode does not work,

the slide-out room can be manually retracted by following these steps.

1. Gain access from either the inside or outside of the unit, whichever is more convenient, to the vertical
channel assembly by removing the OEM trim and flange pieces on the slide-out room box. The motors
are currently located at the top of the channel.

2. If applicable, use a Phillips head screwdriver to remove the top screw from the bulb seal at the top of
the vertical channel (Fig. 11).

3. Pull down the bulb seal and remove the motor cover (Fig. 12). The motor cover may stick to the bulb
seal.

4. Using a 5/6" open-ended wrench or ratcheting box wrench, loosen the motor retaining screw from
the block by turning 2 - 34 turn, (Fig. 13) .Do not remove the motor retaining screw.

5. Unplug the motor from the harness and remove the motor by lifting it up and out of the column.

6. Repeat steps 1-6 for the other side.

7. Push the slide-out room uniformly into the retracted position.

8. Once the slide-out room is retracted, secure the slide-out room in place by:
A. Re-installing the motors.
NOTE: Make sure the motor is properly seated on the block with no gap between the mounting bracket
and block.
B. Torquing the motor retaining screw to 40 in lbs. (Fig. 13) with the motor retainer fully engaged.
C. Using a transit bar (slide-out locking bar).
9. Have the slide-out room serviced by the OEM-authorized dealer as soon as possible. Do not operate
slide-out room until service is complete, as damage to the slide-out room may result.
