I picked up a Kenmore canister vacuum today with the Powermate power nozzle. The overload protection reset switch is broken. Under the cover is a small plastic housing that says Mel Rain / Littlefuse 742332. I would like to see if I can replace this device, as the red button on top is broken and the bottom part is broken as well. Does anyone know where I could order a part like this? Thank you in advance. Mark
