After 20 years, the compressor on our aft cabin AC unit has died.  Cause of death is a failure of the internal check valves, so the motor runs, but doesn't pump refrigerant. Not an unusual failure mode in this type of unit.

Seems crazy to put a new compressor into a unit as old as this.

The specifications for the original Cruisair SX7C described a 60hz unit that ran at reduced capacity when run at 50Hz.  I can not find a similar statement in the specifications for current production units.  Can someone confirm that current Cruisair units specified as 60Hz models will run happily at 50Hz?
