A corgi local mate has just changed a holed diaphragm in one of these which was fine on CH.
Afterwards, CH light slowly flashing indicating flame rec or pcb. Main burners light then it goes to lockout very soon. Once it flashed before even trying to light. Doesn't know what he could have done to the pcb but changed it.
Exactly the same. Then he called me!
Electrode resistance checked back to a pad on the board , nice and low.
Um.
I once had a similar thing , which was cleared by wiggling the board connector - is there something which could have been knocked?
Bad earths are the only thing I've since thought of, to look at.
