Disposal makes a high-pitched squealing or chirping noise when running

Safety first: Turn off power before inspecting.

• Inspect for debris: Look into the chamber and remove any small metal or hard plastic pieces with tongs.
• Flush with ice: Grind a batch of ice cubes to help dislodge minor rust or debris.
• Listen again: If squealing persists with a clean chamber, the noise likely comes from internal bearings.
• Plan replacement: Bearing noise will usually worsen over time. Replace the disposal when the noise becomes objectionable or performance declines.
