    hi, I have 1 radiator which won't warm up. Watched a few guides and think I have narrowed it down to the trv valve. Only problem is I can't get the valve cover off to check the pin. It's a myson valve if that helps, probably very old.
    Any help would be appreciated and thank you

    Give it a wiggle and pull should pop off

    Shaun you are awesome. Was worried to pull it too much before but a good wiggle and a bit of force sorted it. Pin was indeed stuck and thanks to you I now have a lovely hot radiator.
