samsung mn:RS21FSCV SN:847242BLC00125

Hello guys hope someone can advise me on this domestic fridge freezer.

I found the condenser fan failed. The query is the compressor. The compressor runs for around 30 seconds then cuts off. I suspect this is a safety feature due to the system operating on propane R600. Could anyone confirm this is actually a safety feature and also where can I source Samsung parts.

Cheers
