Hi there... I have a Hail Mary kind of question. I have a Mercury Nutone Scovill range hood in need of a replacement fan and motor. Problem is, there is no model # anywhere on the range hood and the previous owner removed the fan and motor. The control knob says it's a 2 speed fan and that's where the "Mercury Nutone Scovill" nameplate is, but there's no model # there or anywhere. It's 30" wide, 18" deep and 5" high and the metal mesh filter that fits over where the fan should be is 9" square. There's a 3-position white Molex connector where the fan wires would plug in. I've attached photos in hopes someone knows what the model # is for this range hood. Thank you!
