fixing a radiator that is persistently cold on the top half
My radiator is cold on the top half. I've tried turning it on and off a few times but the problem is persisting. What else could I try to fix the problem?

"Check if there is air in the radiator. If you have a combination boiler then the pressure will need topping up afterwards. If this does not solve the problem initially there are further issues."
