Why a single radiator is not working?

Why is one radiator cold and hot?
If you live in a house that spans more than one storey, and only the radiators downstairs are cold, this is likely down to a balancing issue.

What happens if you bleed a radiator with the heating on?
Should I be bleeding radiators hot or cold? Always make sure your central heating system (your boiler) is turned off and your radiators are cold before attempting to bleed them. When turned on, your radiators contain hot water, and you could be at risk of scalding yourself if you bleed them at this time.
Why is 1 radiator in my house cold?

Why is half my radiator cold?
The commonest, and most likely, reason for a radiator being cold at the top is trapped air. Because water is about 900 times denser than air, even if the air is under a small amount of pressure, the air will always float to the top.

Why are some radiators hotter than others?
Some radiators occationally get quite a bit warmer than others. When this happens it usually means that your central heating system is out of balance. In some instances, radiators can be different temperatures due to the distance that water that heats them has to travel from the boiler or pump.
