vokera linea 28he

tomorrow i am going to a vokera linea 28he
showing up fault code 34 (Fan fault)
have you ever came across this before

Was there on Saturday. was told it was the MAIN PCB .( it wasn't of course )
Was also told by vokera it was the transformer and also no

see the problem is. It not getting the right voltage back to the pcb from the fan transformer
it getting about 1.056 ac back to the pcb
But there 240 ac going to the fan transformer

if its not the fan its the venturi, if its not the venturi its the air pressure switch, if its not the air pressure switch its the PCB

when you fault find a boiler keep asking yourself whats it doing now, work out at what point its stopping and youve likely found the problem
