Does the motor on the 2 port valve continue to operate even when the valve is fully open and it can travel no further. I ask this because I have disassembled my 2 port valve to investigate why occasionally the boiler does not get a call to heat the water and noticed that even if I tape the microswitch on the valve in the closed position the motor on it continues to run. Is this normal to keep the valve open and prevent the spring returning it to the closed position.
I was thinking that the controller is on the blink but now I not so sure...
If I turn up the room thermostat the boiler operates as normal..?
