Radiator supply pipe cold

Dal2k Member Posts: 1
Hi. I have 6 radiators and all but one are working. The supply pipe to the cold one is also cold. I went to the basement and followed it from the radiator above the floor and touched ever part and I got to one connector section and it was hot. What would be the cause of this. A blockagr? Corrosion? Is there is easy way to fix this without calling someone.

    Air and/or not enough water in the system. Or a valve is closed.
    Show us some pictures of the radiators, boiler & piping and a close up of your boiler gauge.
