The oven fan motor doesn’t run through lack of supply. Element heats ok. There are two PCBs mounted on top of the oven, one of which I suspect is the problem. Which one is the question? One is listed as a mains board, the other just as a PCB which is the one I suspect. Both boards are visually good, no blown tracks etc, so I suspect a dodgy triac. Just looking for a second opinion really but any help greatly appreciated. Cheers. Steve.
