Radiator Stone Cold after Taking off of the Wall to Decorate

Postby ad213 » Tue May 19, 2015 8:05 pm

I took the radiator off the wall to decorate and when I put it back on it won't heat up. It's stone cold as are the pipes to it. I bled the radiator but no luck. The trv pin moves up and down freely. I've even turned off all the other radiators in the house but it still doesn't heat up at all. Any ideas?

Hi ad213

You say the pin is free, but what actually sticks is the valve washer to the seating. The best, and only positive way of checking would be to disconnect the rad and open the valve.
