Garbage Disposal Making Loud Noises

Why a Garbage Disposal Makes Loud Noises

A garbage disposal that grinds, rattles, or clanks loudly is usually reacting to something inside or under the unit rather than a single worn part. A foreign object caught in the grind chamber, such as glass, metal, or a fruit pit, strikes the flywheel on every rotation and produces a sharp, repetitive clanking sound. A worn motor bearing instead produces a steady grinding or whining noise that continues even with the chamber empty, since the noise originates in the motor rather than the grind chamber. A loose mounting assembly causes a different symptom: rhythmic vibration and rattling against the sink or surrounding cabinet as the unit shifts slightly with each rotation, even though the motor and flywheel themselves are working normally. Noise location and pattern, more than volume, are what separates these three causes.
