Heating advice needed

Does anyone know why 1 radiator in 1 of my rooms is cold when the central heating is on and all the other radiators are hot? I bled it but water came out immediately so does that mean there's no air trapped inside?
I have a combi boiler.
Any sensible advice appreciated as the room is question is freezing cold.
Thanks.

Did it used to get hot? I had a similar problem and found a rad that had been added as an afterthought and plumbed in wrongly!

If both the flow and return pipes at the point of entry to the radiator are getting hot then it might just be sludge which can stem the flow enough to make it feel cold. If the pipes remain cold or only just get warm then it could be the valve or lockshield.

Can you control the flow of water into the radiator by a rotating a knob at the bottom? Sometimes the valve can jam in the off position even when you have turned it fully on (so it looks on but is off).
In some valves you can unscrew the visible bit, and then you can see the actual valve. The bit you have removed, which controls the hotness by rotation, acts by pushing down on the actual valve. Pulling it up gently with pliers might free it. It only needs to move a little, and WD40 or oil might help.
There's probably a maintenance book in the library which will explain it better than me.

Don't pull up the pin on a thermostatic rad valve - push it down rapidly

Firmly tap the thermostatic value, it may free up.

Do a search on YouTube for 'Plumberparts How to Fix One Radiator Not Working' where James will explain what to try. (No it's not a dodgy channel despite the name). HOLD TIGHT!!!

I had the same problem. It turned out that the thermostatic radiator valve had broken and was stuck in the off position. If that's your problem, remove the valve and change the setting manually. You can get a cheap replacement on eBay.
