Thanks Henboy and others who have replied, I will have to get under the couch when I return home next week (?), So far the allen wrench that I stuck in there to replace the broken bolt while traveling has held up to two or three openings and closings. it makes sense that if the motor is moving it would put a lot of stress on that bolt.
You would think that they would know about this problem and fix it before sending these things out! Same as the bent water tank brackets I encountered (fodder for another thread) I bought mine used from a non FR dealer so no warranty for me.
