wouldnt be a bad idea
try joining the wires to the overheat stat and see if the pilot stays on
if it does its the stat
DONT TRY AND RUN THE BOILER LIKE THIS

wood and trees springs to mind 1) Turn the power off first in case you're messing with the wrong wires.
2) Make absolutely sure you can get everything back where it came from.
3) If the two wires from the stat have bare ends, join them with chocolate block.
4) If they have push on connectors you'll have to improvise something but INSULATE IT before you put the power back on.
5) Try to light your boiler. Does it work? Yes - you either figure out how to reset that stat or you get a new one. No - it's not the stat.
7) Turn the power off again and put everything back EXACTLY WHERE IT CAME FROM.
For the pilot to stay on, a small valve inside the main gas valve has to be kept open. You hold it open at first but when you let go the job falls to a tiny electromagnet. This magnet is driven by the voltage from the thermocouple, nothing else.
There are lots of reasons why this system might fail, eg insufficient volts from thermocouple (wrong type, not hot enough), too much resistance in the circuit (bad connection, faulty stat, wires too long) or a faulty gas valve. Let's hope it's not the gas valve!

Can see this man blowing himself and his kids to kingdom come. I assume all you good guys will be able to sleep at night when this happens. It is evident from his post that the chap know nothing about circuitry.
Blind man driving a car on M1 come to mind.

14 yrs no money to pay a fitter not been serviced since dont know when ?????????? this could be a rusty wreck
case seals leaking ( who knows) death not far away why r u helping him to kill himself he seems to be doing a good job on his own
BANZAIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
Who was it that used to shout that ? ah yes Kamikazess
phone any gas company and tell them your skint and can u pay them in 5 instalments dont try to do your own work when u dont know how to
