There are some posts on the forum about an electric bed that failed. In that case the problem was a loose wire and there was an easy fix. If memory serves, remove the vertical front piece (screws are under the "buttons"...I think) for access to motor and wires.
We have the 2100 and electric sofa is our only bed. Thus, it is put in and out every day we are in the RV and it has not failed.
