Product details
This is the Hall sensor idler assembly, part D375-1400, from the Fuller Brush FBP-14PWBP. It also fits the Maytag M700 and the Riccar and Simplicity R10P and R10S. The unit carries the belt idler and the Hall-effect sensor together, so the part that tensions the belt is also the part that reports whether the brush roll is turning.
That pairing is why one failure looks like two. A worn idler lets the belt slip and the brush roll slow down, the sensor reports what it sees, and the machine flags a brush roll fault or shuts the drive down, so the warning light and the loss of agitation arrive at the same moment.
Note how the sensor lead is routed before taking the old unit out, and reconnect it exactly the same way.
