     Tom, you did bring up some good points and these lead to Valid "ifs   
   and buts" -all related to starting.   
   If the load was a fan or similar, there would be no problems but with a   
   compressor, effects of frequency variations with capacitor start may   
   certainly reduce motor starting torque and if there is back pressure ?-a   
   problem. I had thought a fridge compressor did provide a high back   
   pressure at start but it appears that I may be wrong about this- it   
   makes a difference.   
   In addition, there could well be a problem with the centrifugal switch   
   If it's normal opening speed was too high (which is a good possibility),   
     then the starting winding wouldn't be disconnected-not good- smells   
   expensively funny.   
   The transformer, if 60Hz would have to be 288/120V -say 1KVA.   
   Considering the cost of purchase, shipping, transformer etc- it may well   
   be that one should purchase a 240V 50Hz fridge in the first place. A   
   quick search indicates that every major manufacturer of fridges (us and   
   elsewhere) have 240V 50Hz models - some sources have 240V 50 Hz   
   compressors which could replace 120V 60Hz units.   
      
   So it really comes down to experience when trying this.
