Re: [Amel Yacht Owners] AC Compressor Death...

Hi Bill, 

We replaced both of our AC units with Marine Air systems in 2014 while in St Augustine. The manual says they are rated for 230v and 60hz. We contacted Marine Air prior to purchase, and they told us they would do fine at 50hz. We just spent a couple of weeks on the dock in Martinique, ran them every day on 230v and 50hz, and they did fine. 

Good luck getting your AC replaced.

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?
