samsung fridge freezer?

I think a fuse went in my Samsung fridge freezer , I replaced the fuse.
At the top of the fridge,
is the power button 5 lights and a ref temp, (cant see the ref temp doing anything, press it nothing happens)
cant find the model number
before all this the first 2 lights stayed on and 3 were of, now all 5 lights are on and I cant switch any of
