Choose the correct motor and controller version
Lippert revised the electric-step drive system in 2006 and again in 2019. For a Series 34 built with 2006–2018 IMGL components, a failed motor or controller generally requires updating the pair to the newer IMGL-II system. A 2019-or-later step can use the corresponding later-generation replacement parts when the original motor and control numbers agree.

Complete double step 3722862
Lippert 3722862 is a complete Series 34 double electric entry-step assembly with logic control and a power-switch kit. The manufacturer specifies:
Before ordering the complete step, verify the mounting-bolt pattern, door opening and entry height, folded clearance, harness connector and original switch type. A replacement Series 34 frame (3722864) is sold separately and does not include the complete powered assembly.
Step operation and service
Disconnect 12V power before working on the step or linkage. The treads can extend or retract unexpectedly when the door or ignition input changes. Follow Lippert's instructions for mounting, electrical testing and drive service.
