I finally got a plumber round to look at my failing gas boiler.
Basically system fires up, then when it reaches required temperature it
cuts
out - pilot and everything. There is nothing wrong with pilot,
thermocouple
etc and I checked the circuit boards.

Just looking at it, he told me that the fault was the gas valve which
would
need replacing. Of course, like all his brethren, he is too busy to do
this
in the next month or so, but he said it is something I could do myself.

So, is he likely to be correct in his diagnosis?
Is he right to suggest that this job could be done by a competent DIYer?

thanks in advance for any response

Firstly, if he is a plumber then his experience and knowledge of gas
controls is probably very limited. People make the mistake of thinking
plumbers are experts at heating. they are not. they are good at drains and
gutters. The people to go to should be heating engineers. A company that
only does heating - not heating and plumbing.

The wires generally just plug into the valve (make a note of what goes
where). The valve is just a screw in screw out job. Any screwed thread put
on jointing compound.
