thanks for your help ,john,lads its up and running now. the oil solenoid had shorted inside and blew the box . i threw in new fan bearings as well while i waited on new box, so a warm hoose again

i opened up panel and there is no slow blow fuse or anything that resembles a fuse

the overheat stat was ok , top panel still working as normal but no life at burner , i will check this fuse at the pcb next , i have a new control box coming, but theres hope in the meantime if i find a blown fuse at pcb. thanks

your the man! ,thank you very much

I have no action at the burner unit at the moment after changing the fuse .the timer panel and indicator lights are working up top would this be the case if the slow blow fuse on PCB is blown .I'm thinking it may run if I find rise and replace it. I don't have a slow blow fuse would a...

That's a great help john thank n you

thanks john theres an 830 for sale on my doorstep .tempted to go get it as its getting cold in the evenings here in the highlands,

i have soldered behind connector 5 and the fans not kicking in so unless there is a fuse to blow in the timer board where the timer is up top? what voltages should i see from the top board coming down from the timer board to the control box`?

great thanks, so any 832 or specifically 832.3 thanks again

ok folks , i disconnected the pc annd it didnt energise solenoid , i wired the solenoid straight and it worked as it should. the initial problem was the fuse blew on boiler , i changed that and on initial try to start i gave a good spark inside the control box , i have since opened it up...

That's great thanks , the reason I asked the voltage was I'm sure I seen around 45-60 volts at the solenoid . I will double check it when I check the ohms of pc . thanks again

Hi folks , I will have to try straight wiring it next ,what volts do I expect to be going to solenoid when its wired through the control box. I never thought about the photocell ,how do I check it? Its a short 770s,thank you kindly

Hi Bob, I have a complete new pump assembly, so I swapped the new solenoid onto valve still no startup . i tested resistance of new solenoid and it seems bang on. I renewed the control box last year so I'm hoping that's OK. Perhaps the new solenoid is faulty ,neither of these hold a...

hi all , i have the above boiler, if i operate oil valve manually the boiler runs as it should. but assembled as its meant to be the thing doesnt fire because no power going to solenoid . all connections behind control box tight and continuity of cables good. has me kind of stumped. any...
