Anyone had much to do with the Ravenheat CSI aaa primary heat only boilers went to one fan was sized changed fan all good up and running happy days waited half hour all still going just as I'm about to leave locked out again reset it and fired back up got a feeling this will be coming back into me. A previous engineer had changed ignition / fan pcb. Any one had much dealings with them anything common on them? Didnt see it lock out so can't tell at what stage it did it I.e if it dropped out while in full flame or weather it knocked off and tried to re-fire

I had a job on one of these last week, it was firing up for a bout 7 seconds and then it would go out, then fire up again and go out and kept doing it, turned out to be the fan PCB, I spoke to technical who went through it with me, I had to put multi meter on volts ac on the brown wire on fan PCB, and I was getting a reading of 230v then all of a sudden it would drop down to about 50v and fan would cut off, then 230v again and fan would kick in and it just kept cycling like that.

Your case could be the same but when the volts are dropping to the fan it just might not be going back up like it was with me and it's just going to lock out. Just test the brown wire on fan PCB and see what's going on with the voltage, but just keep your multi meter on it until it locks out.

Cheers pal will check but it's had a new fan pcb a month ago the old one had been left on the top of the boiler nothing saying it's not faulty though so will check that I think it's going to be one of them sit in front of it and wait for it to fault
