If your Kwikee 42 Series electric steps are sluggish, stuck, or completely unresponsive, this OEM-grade replacement motor is the direct fix. Lippert part number 379167 -- also listed as Kwikee 1820122 and AM Equipment 210-1009 -- restores full automatic extend-and-retract function to pre-IMGL 42 Series steps manufactured between 1999 and 2005. Drop-in fit, weatherproof connectors, and a built-in obstacle shutoff make this a straightforward DIY repair.
Kwikee 42 Series steps were among the most widely installed electric entry steps on Class A, Class C, and fifth-wheel coaches produced in the late 1990s and early 2000s. Over time the step motor is one of the first components to wear out -- brushes degrade, gearing wears, and the motor loses the torque needed to move the step mechanism reliably. Replacing the motor rather than the entire step assembly saves significant time and cost.
This is the correct motor for pre-IMGL 42 Series steps. If your step controller or wiring harness references IMGL (Integrated Motor/Gear/Limit switch), this is NOT your motor -- you would need the IMGL-series motor instead. Check the label on your existing motor or the date code on your step mechanism to confirm fitment before ordering.
Motor drives the step out when the entry door opens and retracts it fully when the door closes, integrating with the OEM step controller.
Built-in overload protection cuts motor power if the step contacts an obstacle during retraction, protecting the mechanism and preventing damage.
Sealed connectors and weatherproof wiring resist moisture, road spray, and corrosion -- critical for a component mounted under the coach entry.
Matches the original Kwikee motor mounting pattern and connector configuration for 42 Series pre-IMGL steps. No adapter harnesses required.
Kwikee introduced the IMGL (Integrated Motor/Gear/Limit switch) design partway through its 42 Series production run. The pre-IMGL motor (this part) uses a separate external limit switch and a distinct mounting flange. Key identifiers for pre-IMGL steps:
If your steps are post-2005 or the motor and gear/limit switch are housed in a single sealed unit, you need the IMGL-series motor instead. When in doubt, compare the existing motor label to Kwikee part 1820122 before ordering.
Motor replacement on Kwikee 42 Series steps is a manageable DIY project for anyone comfortable working under the coach entry area. General process:
