Kwikee Step Repair


Unfortunately, it looks like the Kincor kit I mention below is no longer available- Kwikee changed the motor enough that it is not possible to take it apart- the unit is not sealed.

An alternate repair method using an Auto Parts store motor is discussed in this RV.NET forum posting.

Original post below——————————–

Electric steps are one of those luxuries that are a near necessity- in a Motor Home, you often need a step to enter, and yet once you are in, you cannot push a manual step in, and when you are in the rig, pulling the step out is impossible.

The vast majority of electric steps are manufactured by the Kwikee Company. These steps are pretty darn reliable, if the maintenance is performed as required, which is easy- simply lubricate the hinge points with a good quality lubricant. Kwikee sells a very good “Kwik-Lube”, which is a kind of “penetrating grease” that starts out thin, but thickens after a few minutes. Others have recommended motorcycle chain lube- I’ve never tried it, but it sounds like it would be good- a good quality lube which does not attract dirt.

But… even with the best maintenance there are a couple of problems that can crop up. I dealt with the most common today. The step was stuck in the retracted position, so… first I check the voltage to the unit. Next, check the grounds and connections (older models have a 4 way connector which has a tendency to corrode- Kwikee changed that a few years ago- the new ones are much more reliable.

So, I remove the motor assembly from the step frame- 4 bolts and the pin which attaches the arm to the step- the 4 way connector, and the connector between the electronics and the motor. Once the motor is off, it still will not run- even hooked directly to a battery. So, I next remove the actual motor from the gear case (3 screws)- as soon as I pull the screws, the motor case rotates at least 20 degrees, indicating it was in a major bind.

This bind comes from the way the motor is designed. The motors are actually power window motors, and they have a small worm gear on the motor output shaft which engages in a large gear (#2), which in turn is coupled to an output gear(#3). This coupling is made by a triangular cutout in gear #2 which contains three small round plastic inserts that a triangular part on gear #3 fit in to.

The round plastic parts are there to absorb the shock when the step hits the end, so that the other gears don’t simply shatter. This works well- until the step gets some age on it, and these small plastic parts get oval, rather than round. This allows the motor to bind up, and because the step electronics sense current draw, and the step motor is drawing a lot of current trying to get out of the bind, the steps get stuck.

Luckily, a company named Kincor has made a gear replacement kit, which includes gear #2, the round plastic parts and a supply of high quality grease. The kit part number is BD52, and it retails for around $30 (a fraction of what a new motor assembly costs).

A quick Google for more information yielded an FMCA Magazine writeup on this kit- along with a picture and company contact information.

    My kwikee steps will not come in when I start the engine

    • August 15, 2015 at 1:46 pm

      Will they go in when the main step switch is turned on? If not, I would bet you have a door switch problem- the door switch will over ride the ignition switch.
      Or, there is usually a low amp fuse on the ignition feed, that could be blown.

    2007 Winnebago with Kwikee 32 steps. The diode / resistor assembly in the wire harness between my coach and steps is damaged. Does anyone know the component sizes and wiring? I believe it is to prevent some sort of electrical backfeed to the ignition. I am hoping to fix this on the road and not wait for shipping of a new harness piece.

    2011 Thor 33′ class a with two step retractable step automatic..goes down and locks fine. When retracting the motor cycles five or six times( steps stay retracted just motor recycles. Is ther an adjustment for the stop (up position). Thanks howard

    got a 2008 Fleetwood terra lx, the steps guit a while back when we were in Florida and it was very HOT. returned to Indiana and cooler weather and they strated working again. Weather got hot and they quit again.. It cooled back down and now they work again. was wondering if there is a relay failing or what could be causing the temperature issue?????

    i remove the pin fr the motor and i push the step by hand and haft way he click is hard to push in what that can be

    • June 1, 2015 at 10:31 pm

      It would have to be something in the step frame itself- if you’ve pulled the pin attaching the motor/gearbox assembly to the frame.

    My Kwikee steps won’t shut off right away when they retract. The motor grinds for a few seconds first. They appear to be fully retracted. Is there a switch that I can adjust or are the gears shot?

    • May 8, 2015 at 2:35 pm

      Hi John,
      That usually means the controller and motor are not getting enough voltage, due to a bad connection. The control senses the current draw to shut off, and a bad connection will limit the current below what is required to shut off. On the older models, the square main plug was the usual suspect- newer models use a much better plug though.

    I have kwikee 2 step model 32. The step would not come out when the door was open but when you close the door you can hear the motor run. Unhooked the motor from the gearbox and the motor only runs when you open the door. Does the motor need to be replaced or the control box?

    • April 27, 2015 at 1:30 pm

      That would point to the control box- if the motor runs in one directiong, it should run in both with no problem.

    I have a kwikee single step model 28 on a 1998 sea view. It has been acting up for awhile and now has stopped in the extended position. Before it froze up I could wiggle the 4 way connector and get it to work. Then it started spazzing out. In and out multiple times. And now nothing I do will make it work. I can wiggle the 4 way and get the step light to come on and a slight bump noise that I used to hear as the step started to work. Any suggestions would be appreciated. This is our first mh and I don’t know where to get replacement parts. Thanks and MERRY CHRISTMAS

    I have cleaned/lubricated and cleaned ground but issue still there. Once steps stop on way up, I can manually move to the correct stopping point. This issue occurred after I replaced the linkage. Is there a correct position to hook up the linkage?

    I can push it all the way in once it stops.

    • November 27, 2014 at 1:50 pm

      I would give it a good cleaning and lubrication- the Kwik-Lube sold by Kwikee is really good stuff. It applies thin, to penetrate, but then gels to heavier grease. Another option is motorcycle chain lube.
      I would also look at the wiring connections- paying close attention to the ground and, if yours is old enough- the 4 way connector off the control box. The newer versions are well sealed, and reliable than the old black square 4 ways.

    Linkage broke on my 2 step Holiday Rambler. Replaced linkage and extends ok. Upon return it goes about 2/3 way in. What do I need to do to make it return 100%?

    • November 26, 2014 at 7:34 pm

      Does it return 100% if you help it in?,- If so, you have a lubrication or power problem. If it has a hard stop keeping it from retracting, you have another mechanical problem.

    I bought a 1994 Airstream Land Yacht in June and on our first trip (an 8500 mile trip thru Labrador and Newfoundland) the step quit working. Thanks to this web site I was able to determine it was the classical failure of the plastic plugs in the motor gear head and was able to buy replacement parts from Auto Zone for less than $8.
    Now works like new.

    Hi, I have a 1999 Fleetwood Bounder with the electrical Kwikee Steps. The 4-way connector that goes from the camper to the motor came apart and rubbed on the road eating up the connector. I am having trouble finding the male and female connector. Do you know where I can order the male and female 4-way connector?

    I have read with glee some of your posts and have great admiration for what you have and are doing. The RVs we live and play with seem so confusing sometimes but are in reality very simple. You definitely have shown a lot of folks the easy way. I just found your site this AM while researching a problem I read about on RV.NET. I love schematics and line drawings for learning and teaching. The Suburban Furnace manual is great, thanks for posting. I’d like the edge connector id and I’ll find that too. Thanks for all you do.

    Have a 2002 Georgieboy Landau class A with the double steps, in the midst of replacing the wood that the steps bolted to. When the steps came down, they came down fairly hard and a piece of angle iron with two slots cut out of it fell and I have no idea where it belongs, any ideas? Thanks

    Do you know what the brass bushing is on the kwikee series 42 steps. Is is recessed in the arms that are used to extend/retract the steps. Fits into the steel strap..
    The bolt fits through.
    Thank you

    A buddy has a 1993 Pace Arrow with Kwikee double step. Gears and wiring look OK but the controller was full of water. The transformer looked fried and we cannot find a replacement for control box #9514; since it was manufactured before 1999. Any ideas or help? Will the replacement for #9514 anyway, even though it was manufactured before 1999?

    My kwikee steps got to where they
    Would only extend if the ignition was left on, now they do nothing, help

      Hi Mike- sounds like a possible battery connection problem, but it’s tough to say for sure.
