Caravan fridge?

My fridge is a RM4271, type C40/110. Stopped working, whilst using on electric power. I heard this could be due to a broken thermo cuppling, I replaced this part and still not working. I am aware the Thermo cuppling works the gas side of the fridge, but it's the electric side that has gone off. I have power to electric switches on fridge but still not woking IE: Not getting cold. Can anybody help??
