check the main supply line to it from the heat source (boiler), if you can't trace it, contact a professional

Shut the valves on the other 3 and see if it heats then. If it does, it may be have been choked with sludge or you may need to slightly close the lockshield valves on the first 3. (i.e. balance the system) If it doesn't heat, try opening the lockshield valve fully, since it is last in the run.
If its a thermostatic valve remove the head and make sure that the pin is free to move, it may have stuck in.

The pump might need turning to a higher setting, if you have one. The inlet and outlet could be blocked with muck. Try turning down the lockshield valve on the other 3 as the system could be out of balance. You need to encourage the water through the cold one so you strangle the flow to the others. If you have thermostatic valves on 3 of them then turn the settings down and open fully the lockshield valves. This is how they should be with a therm static valve. Best of luck.

It sounds to me like the radiator is air locked. There should be a bleeder valve on the radiator (if it's a hot water system) that you can open to release any air that may be trapped. Once the hot water is flowing, the air may move down the line and "air lock" another radiator, so pay attention to the other radiators in your house. Bleeding radiators is a simple process that you should be able to handle yourself. BE CAREFUL! Usually the hot water system runs at 180 degrees.

try turning the other rads down a bit and see if it gets any better, If it doesn't, then you have air locked in the pipework going to this rad. The only way to get it out, is to turn the rad off and drain it out. As it is draining, open the air vent. Then when the rad is empty, undo one rad valve, and let the water run.as it runs you may see the water turn from clean water to black. let it run until the water is hot Turn off the valve and connect to rad. Keep the valve shut, and do the same the other end. Then connect valve to rad, and turn valves on again and vent air from rad. Keep boiler on whilst doing this.

It could be any of the following reasons
1) Blockage in the systems - Try a chemical Flush
2) Failed Thermostatic Rad Valve - Replace valve
3) System is unbalanced if you have opened all the rad valves, so flow is only going to the other rads

You have a fault on the inlet valve on the radiator what is last in line ,stopping the water from circling round that radiator .

99% it's an air block.
