Just had new synchronous motor fitted as central heating was not working and boiler overheating. Now all works were fine except radiator in upstairs bedroom (nearest boiler) is cold and downstairs radiator is cold (same side of house but not directly below each other.)I have bled the system but these two radiators are still cold all others are nice and hot.....HELP!
 
Close one valve on each of the hot radiators, and full open both valves on one of the cold rads.

If this doesn't work, shut off valves on a cold rad, remove rad, take into garden and flush it out, replace.
 
If you have TRVs, it could be the pin is stuck in. Do you have TRVs?
