My Fridge suddenly stopped working, I have a multimeter to test it, but it has 4 connections. Brown - Live, Yellow - Earth, and a grey wire and a white wire. Which two do I use to test. When I test the Grey wire and the white wire, I get a good reading, but when I test the Live and earth - theres nothing.. Would this be saying the thermostats at fault?

Many Thanks
