Entry steps

Was working on setting up toad and opened the door to motorhome, all good. Step came down and I entered. Closed the door behind me. Heard the steps come up and once fully retracted the motor seemed like it wanted to keep closing causing it to loud pop repetively like it is still trying to close fully or not registering it was closed....


Any thoughts?

I suspect it is the crush disks, in the motor gears, needs replaced. Replacing the motor will come with new crush disks and solve the step problem you are having. Step motors are designed to operate a car power window. The torque required to move a car window does not usually cause the 3 disks to fail.

The increased force required to move the rv steps, causes the crush disks to become misshapen. They act like a clutch, when they slip the motor does not produce enough current to signal shut off. Crush disks are available at many auto parts stores. For about 40 bucks you can get a new car window motor that is an exact replacement, then you have everything new. Unfortunately, you and I are not the only folks this has happened to.

Unless you can see an issue with the main gear, replace the motor.

"Crush disks"???
Well, this is the first time I've ever heard of them. I've had mine apart once or twice and have never seen anything that represents anything you're describing. My steps acted just like the OPs only, there was a ratcheting sound when at the end of the travel. On mine, it ended up being a damaged "driven" gear, not the drive gear on the motor. And, as far as I know, I was always lead to believe that those motors are governed by resistance. Once the step hits the end of it's travel, either in or out, the increased resistance is what stops the motor. I'll have to look those "crush disks" up to see what they look like.

On my old mh, I had the same issue. The crush disks, if that is what they are called, were all broken up. They are about 1/2" diameter and 3/8" high. I found that 1/4-20 nuts are almost the same size and worked fine until I found the right part in the help section of Autozone. On my current mh, I had what I though was the same problem and bought the crush disks. Found out the problem was the drive gear was slipping on the motor shaft. Drilled a hole through both and pinned it. Still working fine!

I have a copy of the Kwikee Service Manual but the file is too big to post on IRV2. It also shows different models and replacement part numbers. If you give me your email address (PM or post) I will be happy to send it to you.

There are a couple reasons why these steps fail.

1/. Putting weight on the steps before they are fully extended.

2/. Lack of pivot point lubrication. ALL Pivot points should be lubricated at least twice per year or more often in a humid climate.

So I got this motor home about 2 yrs ago and whenever the steps were fully extended and you stepped on them they gave in about .5 to 3/4 inch.
Just thought it was normal could this have caused it to strip.

And when it started making the noise is when i closed the door and the steps retracted into the closed position, once reaching closed position is when it was are skipping teath on the gear...

Any way to repair or adjust length of movement in gear box to bypass that gear section

Or just buy a new 70 part

At this point your pretty much committed to replace the gear box. There's not a lot of adjustment on these. The stop bumpers can be adjusted slightly. The key to longjevity is keeping them lubricated.
