Has anyone else had problems like this? What was the fix?
It is easy to jam the motor's worm into the plastic drive gear. There are no limit switches, so the motor stalls when the steps lock into open or closed positions. You can disassemble the motor from the gear and free the worm, but I have found that only works for a couple months then the motor jams again. The permanent fix seems to buy a new motor and gear assembly. Be careful as there several motors available for different model Kwikee steps. The transmission seems to be very rugged so I would not plan on replacing it. Makes sure you lubricate the steps every month or every time you drive in the rain. I personally believe that stepping on a moving step or a lack of lubrication causes most motor failures.
