Welcome. My name is ***** ***** would be glad to assist.

When dealing with refrigerant compressors, unless they are labeled as 50/60 hz, they are not interchangeable.

I have never seen a dual rated refrigerant unit, not to say they dont exist.

A 60 hz compressor running on 50 hz will run at 20% less speed and cause major issues with the refrigerant and operation.

Same goes with the other direction, a 50 hz running on 60 hz will run 20% faster.

Unfortunately you need one designed for your frequency.

Let me know anything further,

Thanks

Will a 50 hz compressor working on 60 Hz will consume more current than rated one?
Expert:  AssuredElectrical replied 1 year ago.

The problem is the refrigerant flow will be too great and it will overload the entire cooling system and drive the amperage up too high on the compressor as well.
