Please can anyone help, In my system i have 1 radiator that stays cold. The water gets hot uptill the thomostat,but no futher. I have taken the thomostat off and cleaned around to try and make a connection but with no luck. Do i just need to change the thomosat or is there something else i can do. The system is part of a Worcester Bosch 24 combi boiler. The rad that dosen't work is on the middle floor. the rad on the next floor works ok.

Bleed the radiator with the boiler turned off, try pressing the pin in the TRV by hand - still nothing ? try a couple of sharp knocks on the side of the valve with a hammer or wrench.
