Help with heating controls

[jake987]

Update. I have now fitted channelplus h27xl series 2. To replace the original channelplus. Same wiring as original.but checked nothing loose. Everything fires even though turned off. I gently and repeatively hit the valve for the heating with my screwdriver and now the heating has gone off as it should do as the new programmer has everything off. Don't know if I dare turn it back on now ha

Definitely the culprit, to me
I'm afraid I don't know if you need a whole new valve, or if just the head is available.

The actuator spring return may have gone week or the valve may be sticking, with the heating off you should feel a fairly stiff resistance while pulling the manual lever.

I can easily move the switch with one finger. Doesn't feel any resistance.

the synchron motor in the valve is seizing, either change the motor or the actuator head

 

[jake987]

Iv never done that. Are they easy to change?

 

[ianmcd]

I will say yes but I do this for a living and have changed many of both what make is the valve, post a pic if not sure

 

[jake987]

Honeywell valve. That's a picture of the sticker on the bottom on the valve. Let me know if need clearer pic if that doesn't help.

just do it in situ, only warning, be carefull not to drop the little screw when changing the motor, not that I have ever done that

Thank you. Il order new part and give it a go. Thanks for all the help, glad I stumbled across this forum il put a bowl underneath for when I drop the screw (bound to happen ha)
