Help with step cover not coming up

Headed out today for our first trip of the season. Noticed when leaving the step cover in front of passenger seat would not come up. When pressing the button I can hear the motor running but no moment on the steps. Is there by chance a sheer pin or something similar on the motor shaft broken or loose not allowing the gear to move? Never dealt with the step cover before and not really sure where to begin first. Do you have to access from underneath the coach? Any suggestions would be very much appreciated. TIA

Dave

Probably need a new motor. The motor and gearbox is one contained unit.
Try lifting the cover while applying power. Might get it to engage for a cycle so you can access it underneath.

The first step is to stand outside the coach at the steps, get out a flashlight and look around under the step. The new smartphones are great for getting into hard to reach areas and snapping some photos. You may have broken a pin, or a corkscrew type gear came loose. Unless someone specifically knows what was used in your coach, you need to do some investigation.

Temporarily, you may have to remove the cover and go without it.

Dave, I had an ‘05 KS and had the same problem. The casing on the actuator for the step cover had a tendency to split open, allowing the gears to unmesh. You can repair it temporarily with a hose clamp or two, but ultimately you will have to replace the actuator. To get to it, you can actually lift up on the step cover and since the gears aren’t engaged, it should pull straight up with a little effort.

I seem to be unable to rise steps up to access actuator. Pulled quite hard while also having wife activate switch but no luck getting them to come up. I can see the actuator behind gap between the bottom step and riser. Am I going to need to remove the riser to gain access? It appears if I lift up the rubber glued down mats on steps, there are several wood screws that hold step riser in place which may allow me to get to the linkage and actuator area. Am I missing sometime or any better ideas? Thanks for the help.

Dave, if you are able to see the actuator, it may be possible to get a wrench in there to remove the bolt affixing it to the step mechanism. That's the only other thing I can think of.

Look up linear actuator, about $40. Choose the length and speed that you want. I have to look up the paperwork on the one that I ordered and get the specs. I think it was a 900N speed.

This is the information that I have on the step actuator. The linear actuator without a name is the replacement one that I bought, $33 + shipping. The other one is the original. The other two photos are of the step and actuator and the mount. Without cutting a hole in the lower piece of the step-cover, I do not see a way to get a wrench on the attachment bolt to free the actuator. Others may have a better technique.

Thank you all for the suggestions and information. I will try working on it when I can after we get home. I will let you know what I find out. Thanks again.

Took a look at it after arriving back home. I was able to access the actuator by pulling back a bit of the glued on rubber step cover and removing 5 screws holding the bottom riser on. There was a lot of tension on the two bolts holding the actuator in place which would not allow me to move the steps up or down manually. Removed actuator and I could easily rise and lower steps manually. Actuator would extend and retract when not connected to the steps but when reconnected, steps would not operated as should and would get stuck in either the up or down position. Ordered new actuator for $43.00 and pretty certain this will solve my issue. BTW, crazy range in prices for these things from $40's to $200 plus basically for the same unit. Thanks again for the suggestions and info.

Dave
