Entry Step Replacement: Cost, Hours and Process in Hacienda Heights

An electric step is a small system, not a part. There is a motor and gear assembly, a linkage with pivots and bushings, a controller, a magnet or plunger switch at the door that tells the controller the door state, an ignition input on most coaches so the step retracts when you start the engine, and an override switch inside. A complaint can come from any of them and they present similarly.

The most frequently replaced part is the motor and the most frequently faulty part is not. Worn linkage bushings let the geometry go slack, which loads the motor and makes it groan, and owners hear that as a dying motor. A dirty or misaligned door magnet switch makes the step behave erratically, which reads as a controller fault. A controller genuinely does fail, and it fails in recognizable patterns.

That is why this page is scoped with the in depth diagnostic at one hour at $285, credited against an authorized repair, rather than the systems estimate. An hour on the circuit with a meter tells you which of five parts you are buying, and on this job that hour routinely saves the price of the assembly.

• Motor and gear assembly, tested under load rather than swapped on suspicion
• Linkage, pivots and bushings, the most common actual cause of a rough step
• Controller, tested for the specific failure patterns of the family fitted
• Door magnet or plunger switch alignment and replacement
• Ignition interlock circuit, which is what should retract the step when the engine starts
• Complete assembly replacement where the linkage geometry is beyond rebuilding

It is the one symptom on this page we ask owners to stop driving on. A step that extends at speed is the lowest, most outboard thing on the coach, and the first curb, apron or roadside object it finds tears it out of the sidewall. The damage is never limited to the step, because the mounting structure is bolted or welded into the frame and the step well area above it goes with it.

The cause is usually a door switch that has stopped telling the controller the door is closed, or an ignition input that was disconnected during some earlier repair so the step no longer knows the engine is running. Both are small fixes found in the first diagnostic hour.

Where it has already happened, the scope grows off this page: step assembly, mounting structure, frame outrigger repair if the mount tore, sidewall and skirt repair, and often the step well floor. That combination is a good example of why the cheap line items on this program deserve attention before they become the expensive ones.

Kwikee, now under Lippert, built most of the electric steps in the market and parts support for the common single, double and triple configurations is good, at 5 to 15 business days. Older and unusual configurations get thin, and on those the practical question becomes whether to keep chasing an obsolete assembly.

A manual folding step or a fixed platform step has no circuit to fail, weighs less and costs less to maintain. A Lippert Solid Step style fixed assembly is dramatically more stable underfoot than a hanging electric step, which matters if anyone using the coach is unsteady on stairs. The tradeoffs are ground clearance and departure angle, and on some coaches a fixed step simply will not clear.

We measure before recommending: door sill height, frame clearance, departure angle, and whether the deployed tread stays inside the body line. Anything that hangs outside the body line becomes the first casualty of a tight turn, and we will not fit one that does.
