We had issues with our step on our last trip the middle of last month. I've been too busy to troubleshoot, but it is weighing on my mind. Our step is a Kwikee 2 step as well. The last time I went in the motorhome, the steps were stuck closed. I don't know the date of manufacture, but it is on a 2009 Motorhome.
Ours has done this before, but usually just closing and opening the door again will get them moving. On our last trip we packed the motorhome with the steps stuck closed. When I went to put the temporary step stool inside the motorhome before driving off, the steps extended. They worked fine the rest of the trip, until the journey home. They were stuck closed when we unpacked it.
I hope to troubleshoot it in the next week or so when I get some free time.
