Radiator help please, I’m freezing!

[BloodyCats]

My radiator has decided to stop working, no heat at all getting to it. It used to work and nothing has been done to it that I know of.
How can I make it work again?

It doesn’t have one of those thermostat switches, just this thing on either end.

Have you tried bleeding it? You need a radiator key to turn the valve and let any trapped air out.

Is your boiler firing up? Is it just this specific radiator?

On the assumption that is it just the one, it may be worth turning the "in" fully off, then opening again.

It may be worth a quick check of the boiler pressure, just in case.

It needs bleeding ( let the air out) make sure you protect your flooring and walls as water can escape and it will be black
