honeywell m/valve problem

[londonpuma]

hi forum experts,need some advice/help.
this valve is sticking,if i turn off the power,both valves will let me move the little handle to the left with some resistance,then they both go back to the middle on there own.when power back on,i push the lever on the front valve back to the left and it stays there.what is the middle setting,i know the left says man and the right is auto,and should it allways be in the middle.
with the power back,if i set the h/w to 24hrs or override the controls to come on the boiler wont fire up,it will only fire up if i turn the c/h on aswell.
is it easy to swap out the motor on this model,theres some nos on the valve 8738.
thanks for all advice View media item 35616 View media item 35617or can the motor come out so i can get at the spindle ive read a lot about

Sounds like you have a spicky spindle.
The number for this valve is v4043h1056 thats printed of the case of the bottom of your valve.
The valve don't have a middle position.

you take the complete actuator off.
check the lid has it got a dimple on the top ?

Like this dimple on the top lid.

there was a little screw below where the dimple is,i unscrewed that and took the face plate of completly

 

[seco services]

link don't work.

if the spindles sticking then its the bottom brass part you need not the actuator.
they useally just get crud round them inside causing them to stick.

 

[londonpuma]

on my first post,that is what the valve looks like with the face plate off

well if you have that dimple on the lid then you can remove the actuator without getting wet.

look inside where the cable enters and you'll see a brass screw and oppersite corner at bottom near spring is another screw, undo them and the actuator lifts off.

Thats the actuator.
if the spindles jamming it'll be the brass valve at fault not the actuator.

ok,so if i cant free the spindle then i have to buy the brass valve which comes with the actuator allready attacthed,is that right,which will mean draining the system,is that right,ta
