Would that part of the connector block missing stop the pcb from functioning? Also, what do you mean by using a chocolate block single connector for just that pin?

Had the usual blown pcb on one of these today, but when taking the pcb out, the top left lead (the power one) had a pin stuck init from the old pcb. When I removed it (which was difficult enough) it seems to have removed a metal strip from inside the connector block Can this block be fixed or...

Ok ill clean out the pilot injector and see what happens Also, to get to the pilot adjuster, do I have to remove the black box on the front of the gas valve?

Had a call out for one of these the other day, pilot wouldnt stay a light Customer said he had had 3 thermocouples replaced in the last 8 months. Upon inspection, its clear that it isnt the t/c that is the problem, but the pilot isnt big enough to go onto the t/c I have tried looking...

Permanent live? I thought only 2 port valves had permanent live, and that 3 ports were switched live?

Apart from having 2 less wires, whats the difference between a 3 wire and 5 wire 3 port valve? What do the extra 2 wires do? Thanks

So what would you guys do if you came across one as part of a landlords certficate??.....find any excuse to close it down? (Im not being sarcastic by the way, thats a genuine question)

Changed pcb and all is now working

Its the classic FF350.... yeah that part is still on the fan, have told him it needs a new one. Surely if it was the gas valve, the new one wouldnt be doing the same thing? And would that affect the power to the 2nd solonoid when connected? Like I said, on both valves, when the leads to...

This is with the new gas valve....

UPDATE: If I leave the leads on the second solonoid, it continues to spark and the 240v to the second solonoid comes and goes quickly (on and off twice a second) and it doesnt go to full gas. You can hear the second solonoid opening and closing quickly If I take the leads off of the second...

Have told that to the customer, but I was more concerned about making the correct diagnosis with regard to the gas valve. Theres no way the pcb (or any other component) would make the gas valve behave like that would there?

Went on a breakdown tonight and this was the boiler. They said it hadnt worked since friday, and was working fine before that When I got there, the fan was stuck, so eventually managed to free it and got it going with some wd40 It then lit the pilot but when going to full gas (which it...

As always, thanks for the all the help, ive really learned a lot from this

To be fair, I think the only reason he did it was because 1) It wasnt a private job so neither he or the tenant was paying and 2) He had about 10 of the pcb's on his van anyway!! Wheres the best place for me to learn about this type of testing? I know how to check for correct...

Could someone not just give me a quick description of what I need to know, so at least I can start researching it myself thanks

To be honest, I dont think they know either........ Thanks anyway

Never had to know it before now, thats why im asking :roll:

Not really!! But how can you test for these things when the pcb is blown and there is no power to any components?

No, I dont know how to How would I do that?
