Issues with a Imbera Coca Cola retail cooler displaying code RSF

Hi guys, was looking for some advice on a Coca Cola refrigerator i have which is an Imbera G319… I will reset the unit and the compressor will kick on and run for 6-8 hours before going back to code RSF on the display panel and no longer cooling until once again reset.. seems like it would be a sensor or probe? Please advise if possible.

Information I have on the unit is as follows Imbera G319 Asset code: VM10017871

Please let me know if there is any other information I can provide.
