How about a little more information, which model year do you have, ...?
There is a hidden switch in the upper kitchen cabinet that kills power to the majic bed control switch, did it get turned off. Also there may reset breaker next to the bed control switch, if you are operating on inverter power do the other inverter outlets work, if not the gfci on the inverter itself may have tripped, if the inverter is not running and you are on generator or shore power check the breaker in the lower bathroom cabinet.
