Why is my radiator not heating up?
If just one (or a few) of your radiators aren’t heating up, the most common reason for this is trapped air. If you’ve just turned the heating back on after the summer, air can become trapped in your radiators, causing them to be warm at the bottom but cold at the top. Your radiator should soon be nice and warm.

If improper signal/temperature is registered, the valve will not open and close correctly not bringing in heat to the cabin.
Why does my furnace blower not come out?

What happens if no air comes out of the air bleeder valve?
Watch out: If no air comes out of the air bleeder valve valve, just water, then the radiator or baseboard served by that valve is not air-bound. If nothing comes out of the air bleeder – no air and no water, the system may not be hot enough or it may be air-bound.
When to open an air bleeder valve in a hot water convector?
In a building whose heat is delivered by hot water radiators or by hot water convector units every one of these may have its own individual manually-operated air bleeder valves installed. If one radiator or convector is not heating up, find and open the air bleeder valve to let out air. Close the valve immediately when water begins to come out.
