step control module

I checked the fuses and they looked good so I'm bringing this back to the top. Have any advise at all???

Step model? I just ordered a control box for my 2008 HR. The steps are Quickee steps. Since I see no limit switches the box must measure a rise in current when the steps reach their limit. Does it seem like the steps are getting extremely tight when they close?

If you have LCI/SCS/Coachstep (all 3 are the same step), then your step motor is bad. Doug

The step model is LCI.

We are in Texas and called our dealer, he said to replace the module which we did. I checked the voltage and it was 13+. I also cleaned all ground wires. This did not solve the problem. The dealer has no other suggestions. Has any of you had this happen. What do I do now?

How Dun,
Well Sir, one of the first things I need to know here is, what exactly do you mean by "hammer" several times? You see, the reason I ask that is because I just finished working with a problem on our step that sounds incredibly close to what you're experiencing right now with yours. Ours has been operating just fine for the time we've owned the coach, about 3.5 years. But, we just came back from our annual Quartzsite AZ trip and, upon parking the coach at home, and the step retracted, it made a "hammering" noise for a couple of seconds.

I opened the door, which, extended the step and that went as normal. But, upon retracting the step, it made the hammering again. So, I decided it was time to operate. I removed the step motor and drive mechanism. I put it on the operating table and began to dissect it. I came up with what you see in the pictures.

There's two gears in that gear box. One, the Driven gear, is about 3" in diameter and the other one, the Drive gear, is about 1" in diameter. The driven one, has one broken tooth and one about to break. The drive one is flawless. But, if you look close at the picture of the drive gear, you'll see the broken tooth of the driven gear, lodged in between two teeth of the drive gear.

So, in cleaning things all up, I noticed that the driven gear, only rotates about half way in the total movement of the step, either in or out. That leaves the other side of the driven gear, completely brand new and not used at all. So, because the shaft of the driven gear allowed me to do it, I rotated that driven gear 180 degrees so that, the drive gear comes in contact with all brand new teeth on the driven one.

I put it all back together with new and way better grease than the factory used and, it works absolutely flawless. No noise(s) what so ever. I got lucky on that one. Now, could this be your problem too? Who knows? It's actually quite simple to remove that motor drive assembly and, do some dissecting on the operating table. It would take you about 1/2 hour, from the time you started pulling it off the coach, to the point it's all apart on the work bench. There's only a few moving parts so, it's not very hard. Take a look at the pics and see what you think. Maybe it's your same problem.

Thanks Scott, I will look at that. Will let you know. Thanks again.

Yeah, I would definitely say its a gear issue vs. an electrical one. Either it is off on the gearing or there is a shutoff switch when the steps retract or go out that is not working.

You have a Kwikee step. The OP has an LCI and is a different animal. His problem is the step motor. Doug

Why not contact Kwikee ,They are very nice and might send parts FREE ?

Doug,
Well Sir, I didn't know he had a different brand step. Learn something every day. Trouble is, I always forget what I learned the day before. Thanks for the info.
