You have a 2010 unit the same year as mine. This spring I thought my motor had gone bad also as my steps wouldn't close either. I drove it to the nearest camping center. They looked at it from underneath and said that I needed a new motor/power supply and they would have to order it. Price quoted was over $200.00. I came back home. During football season we camp at Lake Lurleen Srate Park in Tuscaloosa, Al. Close by there is a RV center, Country Roads RV, that done some work for me before. I called and talked to their Tech. He told me to stop by and he would check the step. He had it for about 25minutes and came back in and said it was only jammed. Loosened it, greased it and has worked like a charm ever since! Charged $20.00. Could yours be jammed?
