Garbage disposal turns on but then slows down noticeably under even small loads.

Safety first: Turn off power before any electrical checks. Use a qualified electrician for voltage measurements if you are not trained.

• Step 1 – Test with no load: Run the disposal with water but no food. If it still sounds weak or slow, the motor may be failing.
• Step 2 – Check circuit load: Turn off other major appliances on the same circuit and retest. If performance improves, consider moving loads to different circuits.
• Step 3 – Inspect for mechanical drag: With power off, rotate the shaft with a hex wrench. It should turn smoothly without binding.
• Step 4 – Replace if weak: If the motor remains weak despite proper voltage and no mechanical binding, replace the disposal.
