Garbage disposals

Brand-new garbage disposal jams right away

A new disposal that jams almost immediately usually has a leftover shipping item inside it or was fed something too tough too soon, rather than being defective.

Symptoms

  • New disposal jams within the first few uses
  • Grinding sounds unusually harsh from the start
  • Reset button trips quickly on a brand-new unit
  • Problem started with the very first or second use

Likely causes

  • CommonShipping debris or a small part left inside the chamberOccasionally a screw, protective piece, or packaging fragment ends up inside during manufacturing or unpacking.
  • CommonFed hard or fibrous food too soon without breaking it in gentlyEven a healthy new disposal can jam on tough items like corn husks or large bones.
  • PossibleImproper installation causing flywheel misalignmentAn unevenly mounted unit can bind slightly and jam more easily.
  • Less commonManufacturing defectUncommon, but new appliances can occasionally have a defect covered by warranty.

What to do

  1. Turn off and unplug the new disposal before inspecting.
  2. Shine a flashlight into the chamber to check carefully for any shipping debris, screws, or packaging remnants.
  3. Remove anything found with tongs and turn the flywheel by hand with the hex wrench to confirm it now spins freely.
  4. Check that the unit is mounted evenly and fully locked into the mounting ring, not sitting at an angle.
  5. Restart with gentle use: soft food scraps and plenty of water for the first several uses.
  6. If jams continue with no debris found and even mounting confirmed, contact the manufacturer about a possible defect while the unit is still under warranty.

Tools and parts

  • 1/4-inch hex wrench
  • Flashlight
  • Tongs

When to call a pro

If a brand-new disposal keeps jamming with nothing found inside and proper mounting confirmed, contact the retailer or manufacturer for a warranty exchange.

Safety

Use caution

Keep power off while checking inside a new unit for shipping debris, same as any other jam.
