Lost power to sofa bed.

[Sinman5386@aol.com]

I have a 2010 Roadtrek RS Adventurous (2009 Mercedes Sprinter diesel. On our latest trip, the power to the electric sofa bed cut out in mid movement. I have checked all the fuses I could find, including at the inverter, and have not found a bad one. Is there a circuit breaker i’m missing or hopefully some other simple fix? Everything else seems to be working fine, but the switch to the bed is totally unresponsive.
