One radiator not working...please help

[kugacount]

Hello,

I have a 7 year old Combi bolier system in my flat and one small radiator has stopped working.

I bled all the radiators first, no joy.

I have checked the TRV and unscrewed it, the pin is moving up and down okay.

I have also switched the lockshield on and off a few times incase the valve was sticking.

Both tailpipes to the radiator are cold....any suggestions


Cheers

Is it microbore -very small 10mm, pipes

The down pipes are about that size. The whole system is connected by that rubbish fastfit rubber stuff

My last thought would be to shut down all radiators at each end and turn the heating on, try and force the issue, however I might damaage the rubbish piping under floor, any suggestions are welcome!

Cheers

Tool the TRV off again and hit everything abit with a light hammer, seems to have worked!

Hooray for brute force!

Thanks all
