Refrigerator Relay - Need replacement
The relay is similar to a Panasonic JW1AFSN-DC12V relay, cheaply available from various online sources (and likely of higher quality than Sanyou).  

As the part number implies, the nominal coil voltage is 12V, so the relay expects to see about 12V across the coil to turn it on. As @markrages said, you need to check that first before mucking with replacing a PCB-mount relay- there are a number of reasons why the relay might not be pulling in, including a dead power supply, but based on your other comments about fans and display functioning, Mark's caution about a protection switch working (or not) could be the culprit.
