One cold radiator

[longbloke23]

Hi
One of our radiators has stopped working.

I've removed the TRV and checked the pin which looks fine - pushed it in and out a few times to make sure it isn't sticking. That hasn't helped.

Pipes leading away from the radiator on both sides are cold.

Any thoughts on what else I can try before getting a plumber in?

Thanks a lot

try turning some of the other rads off at the wheelhead/trv end and see if the cold rad starts to warm. if it gets hot turn the others back on and see if the cold rad stays hot. if not possible blockage in valves/pipes/ rad? or rad being starved
