Central heating stopped.. fuse blown. I disconnected the pump fuse blew, disconnected the motorised valve no blown fuse but obviously no central heaying as pump wont run.
Does this sound like the Motorised valve or have i just disconnected the signal from another source. If it is how can i test what part is broken can you test the motor?
It is a Drayton mid position actuator MA1.
If it is the MV can i just replace the motorised box, that comes off via a button or do i have to unplumb the whole thing? it is blumbed via 2 compresions and one decidedly nasty looking threaded joint.
If i need a new one what is the best one to buy?
Also can i wire it so that i just have CH and HW until i get a new part?
any help would be appreciatted
