Remove Danfoss thermo valve

[Will DIY]

Ive unscrewed the plastic as much as i can. Dont seem to be any other screws to turn. Does anyone know how this comes off? If i pull it off and break it am i going to flood the bathroom or will it just remain on until I get a replacement? Thanks

Just pull it off. It will expose a pin that the head pushes up and down to control the heat. It's this pin being stuck up or down that is a common cause of rads being permenantly on or off. If it's stuck give it a spray with some GT85 or similar and a gentle tap to free it up. Don't pull on the pin too hard cos then you might get wet!

Do you mean pull off the whole thing?

Pull all the plastic off all the metal. You'll need to twist it (over not round) and be a little assertive with it.

And leave it on full, like in the picture, when putting it on/off.

Got it off thanks. Pin goes in a bit when i put pressure on with hammer so seems ok? But no heat. If you can advise. Cheers.

I've never known a Danfoss rasc2 pin to stick. Take the rad off and open each valve individually into a bucket to check you have flow through them. You can also do this without taking the rad off by taking the vent cap out. Screwing in a 15mm compression elbow with some ptfe on the thread on one end and a 15mm pipe connecting to a hose on the other end and opening each valve individually

If it's an airlock try turning off all the other rads except the one you want to get warm, the air should blow through.
