Repair or Replace? A Quick Guide

Garbage disposals are workhorses that most homeowners take for granted — until they stop working. Here's how to know whether yours needs a repair or replacement.

Signs It Needs Repair

  • **Humming but not spinning** — Usually a jam. We can often fix this in 15 minutes by clearing the obstruction and resetting the unit.
  • **Slow grinding** — Dull blades or minor obstruction. Repairable.
  • **Intermittent operation** — Could be a loose electrical connection or failing switch.
  • Signs It Needs Replacement

  • **Leaking from the bottom** — This means the internal seals have failed. Not repairable cost-effectively.
  • **Persistent bad odor** — Even after cleaning, if the smell won't go away, internal buildup may be too severe.
  • **Frequent resets** — If you're hitting the reset button weekly, the motor is failing.
  • **Age** — If your disposal is over 10 years old and having any issues, replace it.
