i have no power getting to my boiler, i have checked the fuse in my boiler switch and i have checked the two glass fuses in the boiler itself. I have 240 volts at my boiler switch and again 240 volts going to the component board in my combi boiler but still no lights on my boiler totally dead please help.

i forgot to say make sure you have the 240v supply wired the right way around.

if you have 240v at the fuse on the pcb itself it is most likely the board has gone down.you can power down and remove the board, check for any dry joints or blown components.had a similar problem last year, got a board off ebay £120+
