Does it appear that the motor is trying to work, but the mechanical part of the steps is just jammed? You might try getting under there with some WD-40 or spray graphite lubricant, and see if you can free things up.
I would disconnect the motor linkage from the step, to see if the steps move without the motor (which would tell you if it's electrical or mechanical)
If the motor doesn't work, it may be the motor has seized up, or that you have blown a fuse or had some sort of electrical problem (broken wire connection?)
If you take it slow, and use some common sense, you may be able to work you way through it....but, it may also just be that it's old, and something has failed. Did you notice anything previously...like it would make more noise when in motion, or it was slower?

I hate to suggest this but if after you determine you still have power to the steps, take a hammer(wood mallet would be better) and whack the mechanism a couple of times underneath. I have Kwikee steps that love to stick but each time I just tap it a few times and there good to go. On edit....mechanism meaning actuator.

Thanks for all the input! I got underneath the RV witha mallet and pounded it in a few differnt spots and it's now working again. I had kicked it a few times prior to that but the mallet is what did the trick. I put some WD40 on all moving parts and I think it should be good to go. Thanks again!
