Unusual noises, like grinding or clicking, frequently indicate mechanical problems within the motor or gear system.
Another prevalent issue involves inconsistent operation – the steps might work intermittently or require multiple attempts to extend or retract. This points towards potential wiring problems, a failing control module, or a malfunctioning rocker switch. RV owners also report steps not responding at all, usually indicating a complete power failure or a blown fuse.
Furthermore, problems with the door sensor integration can cause the steps to operate unexpectedly or not at all. Identifying the specific symptom is crucial for narrowing down the potential causes and implementing the correct troubleshooting steps. Regular inspection and preventative maintenance can mitigate many of these common problems.
Step Motor Issues & Diagnosis
Kwikee step motor problems often manifest as sluggish movement, incomplete extension or retraction, or complete failure. A key diagnostic step is checking for power at the motor connector while the steps are commanded to operate. Lack of voltage indicates an upstream electrical issue, while presence of voltage suggests a motor fault.
Visually inspect the motor for any signs of physical damage, such as cracks or burnt wiring. Listen for unusual noises during operation – grinding or clicking sounds often signal internal gear damage. Testing the motor’s resistance using a multimeter can reveal open windings or short circuits.
If the motor engages briefly but lacks the strength to complete the cycle, it likely indicates a weakening motor or internal friction. Uncoupling the linkage allows for direct motor testing, eliminating potential binding as a factor. Replacement is often necessary for severely damaged or weak motors. Always ensure the replacement motor matches the original specifications.
Control Module Troubleshooting
The Kwikee step control module acts as the brain of the system, receiving signals and controlling motor operation. Troubleshooting begins with verifying power supply to the module itself. A faulty module often presents as unresponsive steps, even with a functioning motor. Inspect the module for any visible signs of damage, such as burnt components or corrosion.
Testing the module’s output signals to the motor is crucial. A multimeter can confirm whether the module is sending the correct voltage and signals when the steps are activated. Many users have successfully resolved issues by replacing the control module, as demonstrated in online repair videos.
Before replacing, check all connections to the module, ensuring they are clean and secure. A loose or corroded connection can mimic a module failure. Refer to wiring diagrams to confirm proper connections. Replacement modules often require programming or initialization, so consult the manufacturer’s instructions.
Wiring and Connection Checks
Kwikee step malfunctions frequently stem from wiring issues. Begin by meticulously inspecting all wiring harnesses associated with the step system, paying close attention to areas prone to chafing or damage – particularly where wires pass through the RV’s frame. Look for cracked insulation, exposed wires, or corrosion at connectors.
A crucial step is verifying the ground connection. A poor ground can cause intermittent operation or complete failure. Ensure the ground wire is securely fastened to a clean, metal surface. Use a multimeter to check for continuity between the ground wire and the RV’s chassis.
Inspect all connectors for corrosion or loose connections. Disconnect and reconnect each connector, applying dielectric grease to prevent future corrosion. Trace the wiring diagram to confirm each wire is connected to the correct terminal. Don’t overlook the pigtail connector, a common source of problems.
Pigtail Diagnostic Procedures
The Kwikee step pigtail, a short wiring harness connecting the step motor to the main control system, is a frequent failure point. Begin by visually inspecting the pigtail for any signs of damage – cracked insulation, bent pins, or corrosion. A dedicated 4-way pigtail diagnostic manual is available for detailed testing.
Using a multimeter, check for continuity on each wire within the pigtail. Compare the readings to the wiring diagram to ensure each wire is functioning correctly. Pay particular attention to the power and ground wires. Intermittent connections are common, so flex the pigtail while testing.
If continuity is absent or erratic, the pigtail likely needs replacement. Carefully disconnect the pigtail from both the step motor and the control module. Ensure the replacement pigtail is correctly wired, matching the original configuration. Proper connection is vital for reliable step operation.
Linkage Binding and Adjustment
Kwikee step linkage issues often manifest as slow, jerky step movement or complete failure to extend or retract. A common diagnostic step involves decoupling the linkage to manually operate the steps, identifying any points of resistance. Inspect all linkage arms and pivot points for obstructions, rust, or damage.
Lubricate all pivot points with a suitable spray lubricant, such as white lithium grease. Ensure the lubricant penetrates the joints to reduce friction. After lubrication, manually cycle the steps several times to distribute the lubricant evenly.
If binding persists, examine the linkage for bent or misaligned components. Adjust the linkage according to the manufacturer’s specifications, ensuring smooth and unrestricted movement throughout the entire range of motion. Proper adjustment is crucial for preventing strain on the step motor and ensuring reliable operation.
Self-Centering Rocker Switch Problems
The self-centering rocker switch is a primary control for Kwikee steps, allowing operation in both directions. A malfunctioning switch can prevent the steps from responding to commands. Begin by visually inspecting the switch for physical damage. Test the switch’s continuity using a multimeter to confirm it’s sending signals when pressed in either direction.
A common issue is a worn or dirty switch contact. Try cleaning the switch contacts with electrical contact cleaner, ensuring the cleaner is safe for plastics. If cleaning doesn’t resolve the problem, the switch likely needs replacement.
Verify the wiring connections to the switch are secure and free from corrosion. A loose connection can interrupt the signal to the control module. When replacing the switch, ensure it’s the correct model for your Kwikee step system. Proper switch function is vital for reliable step operation and user convenience.
Step Position Sensor Faults
Kwikee steps utilize position sensors to determine whether the steps are fully retracted or extended. Faulty sensors can lead to erratic behavior or prevent the steps from operating correctly. A malfunctioning sensor may send incorrect signals to the control module, causing it to inhibit step movement as a safety precaution.
Diagnose sensor issues by checking the sensor’s resistance with a multimeter. Compare the readings to the specifications outlined in the Kwikee service manual for your specific step model. Inspect the sensor’s wiring and connector for damage or corrosion, ensuring a solid connection.
If the sensor itself is defective, replacement is necessary. Proper alignment of the sensor is crucial after installation; misaligned sensors will provide inaccurate readings.

Overload Protection & Resetting
Kwikee step systems incorporate overload protection to prevent motor damage from excessive strain. If the steps encounter significant resistance – due to binding, ice, or obstruction – the control module may activate this protection, halting operation. This is a safety feature designed to avoid burning out the step motor.
Typically, an overload condition will result in the steps ceasing movement mid-cycle. To reset the system, disconnect power to the steps for a short period (approximately 30 seconds). This allows the control module to clear the fault. After reconnecting power, attempt to operate the steps again.
Repeated overload events indicate an underlying issue requiring investigation. Don’t simply reset the system repeatedly without addressing the root cause. Check for linkage binding, obstructions, or a failing motor. Ignoring persistent overloads can lead to permanent step motor failure and costly repairs.
Manual Operation & Testing
Kwikee steps often feature a manual override, allowing operation even with electrical issues. Locating the manual release mechanism varies by model, but it’s typically found near the step motor or linkage. Engaging this release disengages the motor, enabling you to physically move the steps in or out.
Manually operating the steps is crucial for diagnosing binding or mechanical resistance. If the steps are difficult to move by hand, investigate the linkage for obstructions or tight spots; Smooth manual operation confirms the motor and control module aren’t the primary problem.
Testing the motor independently can also be performed, if accessible. Applying direct power (with appropriate voltage and polarity) should cause the motor to extend or retract the steps. If the motor fails to respond, it likely needs replacement. Remember to disconnect power before attempting any manual or electrical testing to prevent accidental operation or injury.
