Dumb newbie here, trying to identify the mystery part soldered into the windings of an electric household fan. The fan doesn't work, and when plugged in and turned on has 120V across the (two) leads of this part, which is roughly 5/16 x 1/4 x 3/16 and made of black plastic displaying the marks "Elsen (next line) WA128 (next line) PSGF128C". The fan has no obvious fuse, and I am wondering if this is a solid state fuse. The fan has three speeds and different interwound windings, all with different colors, and all going through this part. Anyone with any ideas as to what this is, please post. Anyone with ideas as to what the markings mean, likewise. All help is appreciated.
