Lippert / Kwikee 42 Series Pre-IMGL 1-Year Warranty Lippert 379167 -- Kwikee 42 Series Pre-IMGL Replacement Step Motor

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.

Restore Your Electric Steps the Right Way

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.

Automatic Extend and Retract

Motor drives the step out when the entry door opens and retracts it fully when the door closes, integrating with the OEM step controller.

Obstacle Auto-Shutoff

Built-in overload protection cuts motor power if the step contacts an obstacle during retraction, protecting the mechanism and preventing damage.

Weatherproof Wiring

Sealed connectors and weatherproof wiring resist moisture, road spray, and corrosion -- critical for a component mounted under the coach entry.

Direct OEM Replacement

Matches the original Kwikee motor mounting pattern and connector configuration for 42 Series pre-IMGL steps. No adapter harnesses required.

Fitment Details -- Pre-IMGL vs. IMGL

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:

  • Steps manufactured approximately 1999 through 2005
  • Motor and limit switch are separate, discrete components on the step arm
  • Motor connector is an external plug -- not integrated into the gear housing
  • Kwikee 42 Series steps found on many Thor, Coachmen, Fleetwood, and Forest River coaches from that era

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.

Cross-Reference Confirmed: Lippert 379167 = Kwikee 1820122 = AM Equipment 210-1009. All three part numbers refer to the same motor. If you have a quote or invoice with any of these numbers, this is the correct listing.

Installation Notes

Motor replacement on Kwikee 42 Series steps is a manageable DIY project for anyone comfortable working under the coach entry area. General process:

  • Disconnect the coach 12V power or pull the step fuse before starting
  • Manually retract the steps if they are extended (use the manual override if needed)
  • Disconnect the motor wiring harness at the weatherproof connector
  • Remove the motor mounting fasteners -- typically two or three bolts on the step arm bracket
  • Install the new motor, reconnect the harness, and restore power
  • Cycle the door switch several times to confirm full extension and retraction
12V DC Operation: Kwikee 42 Series step motors run on 12V DC power from the coach electrical system. Confirm your step circuit fuse and wiring are in good condition before replacing the motor -- a corroded harness or failed controller can burn out a new motor quickly.
Maintenance Tip: While the step assembly is apart, inspect the step linkage pivot points and apply a light coat of silicone lubricant or white lithium grease. Stiff linkage puts extra load on the motor and shortens its service life.
Heads Up -- Step Controller: If the motor turns but the step does not move, the issue may be in the step controller or limit switch, not the motor itself. Diagnose the full circuit before assuming motor replacement alone will resolve the problem.

Important Information
  • This motor fits Kwikee 42 Series pre-IMGL steps only -- approximately 1999 through 2005. It does NOT fit IMGL-series step motors where the motor, gearbox, and limit switch are integrated into a single housing.
  • Verify your existing motor label matches Kwikee part 1820122 before ordering. Incorrect motor selection can result in a non-functioning step or wiring incompatibility.
  • Disconnect 12V coach power or pull the step circuit fuse before beginning any motor removal or installation work.
  • The motor includes obstacle auto-shutoff protection, but do not rely on this feature as a substitute for proper step inspection and maintenance.
  • A failed step controller or damaged wiring harness can burn out a new motor. Diagnose the full circuit if the previous motor failed prematurely.
  • Weight: 10 lbs. Confirm shipping address and delivery access before ordering.
