I have a Frigidaire BM1393 and the power head no longer operates. I confirmed 120V at the wall connection, and have voltage at the four copper bands at the end of the hose inside the handle. I do not have voltage, however, where the wand plugs into the handle when I turn on the switch. My guess is that the switch is bad as all of the wire connections (the two lighter gauge white wires that I believe signal the vacuum motor to come on, as well as the heavier black and white wires that I believe power the beater brush motor) seem solid.
Do you sell the switch as well as the other handle "innards", or perhaps a new handle without the hose?
