Central heating control unit blowing fuse

Hi,
I have a Drayton Central Heating control unit ( i.e. controlling the
times the heating and water come on ) which keeps blowing the 3 amp
fuse protecting it.
Is it the controller or what the controller is switching ?
i.e the boiler or associated bits, the pump for example
Is it a case of getting a new unit ( and how complicated is that to
fit) or is there any likely chance of repair.
If you were the sort that could repair it, I would have thought you
would have got inside and tried without asking
but you're asking a how long is a piece of string question
As far as I know the unit is about 8-10 years old as it was in the
house before we moved in.
Since you haven't actually said what model it is, its hard to say as
different ones have different backplates which you may or may not have
to change, depending on age
My feeling is that its probably the further down the line where your
problem lies, programmers don't tend to blow fuses
