I had a similar problem this past winter, I had just returned from having some repairs completed at the dealership and within a couple of days the steps all of sudden did not retract with the door closed or when the ignition turned on. I was a little upset because the dealer was supposed to fix the steps from going in and out on their own, so I thought they had messed up the whole repair and now the steps would not go in. With some further investigation I checked for a in-line fuse behind the steps and next to the coach battery compartment, and sure enough the fuse was blown, I changed the fuse and the steps worked as they should. During my research to find a resolution to the problem I found that we should grease the steps (once a month suggested) to maintain smooth opening and closing of the steps, I had not done any greasing since I purchased the RV over a year and half ago. I believe what happened is the gears got stuck (no grease) and the fuse went. This was my experience maybe you had something similar happen.
