Grinder Motor and Gearbox Assembly
The combination of a stalled motor state and audible noise indicates the motor is energized but unable to translate rotation to the burrs. This is typically caused by stripped teeth on the internal nylon reduction gears or a catastrophic stall due to debris. Replacing the integrated assembly restores the mechanical advantage required for the grinding process.

Conical Burr Set (Inner and Outer)
Mechanical jamming often occurs when a foreign object, such as a stone or unroasted bean, becomes wedged between the burr flutes. This creates a hard mechanical lock that stalls the motor and can cause the high-pitched hum or vibration described by the user.

Grinder Drive Impeller
The plastic impeller located beneath the inner burr can wear down or melt due to friction, allowing coffee fines to enter the drive shaft housing. This buildup creates significant rotational resistance (drag) that can eventually lead to a total motor stall and subsequent gear failure.
