My fridge-freezer is not cooling
My fridge freezer temperatures are too high, the appliance is running hard but it's not staying cool. I pulled it out to check if the back grill was dirty, but it's clean.
What I did notice is that the unit at the bottom (big black thing, Danfoss NLX15KK - I think it's the heat exchange unit) is very hot almost too hot to touch, however the pipe leading off it that goes into the coil/grill at the back of the fridge quickly cools off before the first loop, so the back of the fridge is not distributing the heat as it should be.
This would explain why the fridge and freezer aren't staying cool, but why is the heat not being sent around the coil? Is there supposed to be a pump? Could this be broken?
