My Baxi boiler on light comes on when hot water/heating is called for and thermostats are set high but then nothing happens. Initially this was intermittent but now seems permanent. I have gone through the Baxi boiler manual fault checker and it seem to suggest I need a new PCB. How would I know for sure?
Thanks Ian. No the fan does not run nor the light come on. I have checked the fuse on the PCB and this is OK. Any other checks I could carry out before investing in an expensive new PCB??

does the fan run or the fan on light illuminate? if not then it probably is the pcb.
