Take off the cover of the valve and behind that you will find a pin that controls the water flow. This is prone to sticking if the valve has been shut for some time, pull it out using a pair of pliers cover with smearing of Vaseline replace and that should do the trick. :-)

I had a towel rail rad that was fed by flexi-hoses. There was a slight kink in one which prevented the flow.
As stated it could also need bleeding, or could be silted up (flush the system.
The system could also need balancing - I did mine following a free guide off the net, not at all difficult.
Turn all the other rads off and if this one gets warm it is most likely the balancing, otherwise one of the other problems.
Good luck.

Assuming it is not full of air, and it is not the only radiator, and it is a system with a boiler and a pump which are working etc.
Perhaps all the other values are open and the hot water is finding an easier route

This radiator may have been "balanced" already, and by altering the valve setting you have caused this problem. suggest that you close the flow valve to half way and see if that helps.

Builders don't put inhibitor into their systems, with the result that black rust forms called MAGNETITE which is finer than talcum powder and heavier than steel. This black mud chokes up valves and stops the flow of water, If black water comes out of your system you have magnetite. Cure is flushing and having FERNOX put into system.

Either choked with sludge or the system needs balanced. Is this rad. furthest from the pump??

more than likely to be air in the system. Best thing to do is bleed the readiator and see how it goes then.

Do what John W suggests but also check your boiler pressure...

Sounds like it is in need of bleeding
