Hi guys have a highflow 400 with fan that's pulsating, took hoses off air pressure switch and blew them clean and checked venturi. Connected hoses up again and blew down 1 and fan cam on but didn't fire boiler but was running smoothly. Getting 240 to air pressure and also fan. But the power goes down to about 100 on fan..could there be an issue with pcb guys??
