Any idea where to get a replacement control board for a NV501 machine? Brush motor checks out, but no power going to brush motor (though vacuum suction is fine).

Wife took all apart; quite impressed - but what voltage does beater motor run at? Gotta get a multimeter which are cheap now; Ck red and white leads to cute little motor; and if no power is reaching motor i’ll have the same question as DAVE… and also need to find part (and price of part) if it’s fhe motor …

I’m in the same boat here, Pretty sure my brush motor is going out. It keeps stuttering. I’ve cleaned everything but the filters. If cleaned filters don’t fix the problem, which I don’t know why they would, I need to buy a new brush motor. I don’t want to trash a vacuum only because of a easy to replace motor piece. If anyone finds where to buy it let us know!
