Just a quick one: I have read that if a multiu funtction gas valve (main solenoid) has power to it (and it doesn't work then it's faulty) - Me I would check the resistance of the coil too - open circuit def. faulty...
I have just heard today that it's best to check across live and neutral at the gas valve main solenoid as just checking the live doesn't rule out a neutral fault.
My point is this - if the coil had open circuit you wouldn 't get any reading across live to neutral at the gas valve surely? am i right or being stupid?!
I just wanted to clear this up with anyone who knows for sure - as I usually test fort power to the solenoid between the live and an earth/neutral as main boiler terminal
