I have a 17 year old sta-rite 400 that has never had a problem. We’re in Texas so we haven’t asked much of it. Recently got a service light and the panel light indicates AFS. I shorted the switch and it turned the light off, blew in in the intake tube and that turned the light off too so it doesn’t seem to be the switch. The blower makes no noise at all at any point. Doesn’t even hum. No rat nests and all the wires seem intact. All the signs seem to point to a dead blower motor - anything else I should check?
