I have a problem with Drayton actuator controlling the valve for the central heating. I have replaced this 3 times since January and it ends up with the actuator burning out and smoking when power is applied to it. Just had this one replaced 6 days ago and it looks to be doing the same. The plumber who came out said that the actual valve is okay and the spindle has enough movement without any restriction
The actuator is making a noise when it’s not in operation and I’m assuming the valve is closed. The noise is almost a click every second and an electrical kind of fizzing noise each time. It was working fine initially but obviously something isn’t right.
It’s not burnt out as of yet, but I do t hold out any hope of it not needing replacing again.
What is causing it ?? Video below…
