You know the temperature thing you turn round from like 0 to 5 depending on how hot you want it to be? Well I think, in trying to turn it off I may have turned it too far. As the it just keeps turning but in a jerky movement and the number doesn’t change if that makes sense? Like there’s a little plastic arrow that points up at the setting it’s on, so that you know what setting it’s on. But now it’s like the whole thing is turning rather than just the plastic cover with the numbers on.
So I think (well I’m hoping cos the opposite would be worse) that it’s now turned completely off and there is no way to turn it on. But because the whole thing is turning and the numbers don’t change up or down regardless of which way you turn it, it’s possible it could be on any one of the 0-5 settings but only stuck as showing on 0.
Any ideas?
Cheers!
TRV - thermostatic radiator valve
You should be able to remove the plastic cap. There’s a stem under it. Will pliers turn the stem?
If yes cap plastic is broken. Can be replaced
If not, the whole trv is broken and needs replacing.
The silver ring below the black plastic secures the thermostat to the valve. If you loosen that screw, it will release pressure on the valve which in turn opens -> heating starts. It is rather tricky to fasten that ring again unless you can turn the thermostat to MAX though. Is the silver ring tight right now?
(just re-posting from the other thread - so ignore if you’ve already read!)
It’s a TRV head. You can unscrew it with the ring under the black area - may need an adjustable spanner to loosen. When you take it off, see if the rotation works and that the pin inside moves up and down. You can also check the metal pin/valve where it attaches isn’t stuck (it may need quite a bit of force to check - could need whacking with a hammer if it’s actually stuck). If everything seems OK, re-attach the head and see if it’s working. If it isn’t, new heads are cheap. What you have looks like what I have - cheap generic TRV heads, easy to find online.
