Radiator Stays Hot

[fullyabsorbent]

Hi. All of my radiators have individual thermostats. One radiator will not turn down. Even when it's own thermostat is on the froststat setting it is very hot. When I remove the thermostat the pin seems to be moving freely. Any ideas? 🙂

well if pin moving ok hopefully the body will be ok and just head faulty
therefore maybe no need to drain and replace body
remove head,take to plumbers merchants and see if you can get new valve with same size thread nut head,does not have to be same make
fit new head to existing body,should hopefullyall work ok

Thanks for the constructive advice. I tried the head from another rad on the faulty one and it worked. So no major DIY needed.
