Garbage Disposal parts

Be honest about what a disposal is: a sealed motor in a can. Jams, splash guards, mounting hardware and drain gaskets are all serviceable. The motor is not, and once it is dead the job is a replacement unit, which usually costs less than a technician's diagnostic plus a part.

Find your garbage disposal model number first

No supplier can sell you the right part without it, and the name printed on the front of the appliance is not it.

  1. On the side of the motor housing

    Under the sink, on the black or grey body of the unit. A torch and a phone camera held underneath beats trying to read it directly.

  2. On the bottom of the unit

    Some brands print it on the base plate next to the reset button and the hex socket.

What the tag looks like

Short — often a model plus a horsepower rating such as 3/4 HP. For a replacement, horsepower and mounting system matter more than the exact model: a three-bolt mount and a twist-lock mount are not interchangeable without changing the sink flange.

What fails on a garbage disposal

Ordered most-replaced first. Prices are typical retail ranges for the part alone — not quotes, and not including labour. Confirm the part against your model number before you order.

Garbage Disposal replacement parts with symptom, install difficulty, typical retail price and expected lifespan
PartWhat you noticeInstallTypical priceLifespan
Splash guard / baffleCheck first: Pull it out and look at the underside — the flaps harden, curl and trap food. On many models it lifts straight out with no tools.Water spitting back up out of the drain, or a persistent smell that cleaning does not fix.easy10–20 minutes$8$28Aftermarket is fine5–10 years
Discharge tube and gasketCheck first: Dry everything, run water and watch. A leak at the elbow is the gasket; a leak at the top flange is the sink mount; a leak from the base of the can is the motor seal, and that one means a new unit.Drip under the sink that appears only while the disposal is running.easy20–40 minutes$8$30Aftermarket is fine5–12 years
Sink mounting assemblyCheck first: Flange, fibre gasket, backup ring, mounting ring and snap ring. If the snap ring has lost its spring, replace the whole set and re-bed the flange in fresh plumber's putty.Unit hangs loose, twists when you load it, or leaks at the top of the flange.moderate1–2 hours$15$50Buy OEM10+ years
Jam wrench and resetCheck first: Kill the power at the wall switch and unplug it. Work the quarter-inch hex socket in the base back and forth until the flywheel turns freely, remove whatever fell in with tongs, then press the reset button underneath. Never reach into the chamber.Unit hums but the plate will not turn.easy5–15 minutes$5$15Aftermarket is fineTool, not a wear part
Stopper or batch-feed switchCheck first: The magnet in the stopper is what closes the switch. Try a known-good stopper before assuming the switch has failed — losing the original is the more common story.Batch-feed unit will not start with the stopper in place.easy10–20 minutes$15$55Buy OEM5–12 years
Replacement unitCheck first: Check the breaker and the reset button before you accept the motor is dead. If you buy the same brand you can usually reuse the existing sink flange, which turns a two-hour job into a 30-minute one.No hum at all with power confirmed, or water leaking from the seam of the body.moderate1–3 hours$90$380Either works8–15 years

Easy · 4

Screwdriver, maybe a nut driver

Moderate · 2

Nut drivers, multimeter, a helper for heavy panels

Advanced · 0

Full socket set, multimeter, and somewhere to lay the machine down

4 of these 6 parts need nothing more than a screwdriver. Before you accept a repair quote on a garbage disposal, it is worth knowing which tier the part sits in — the labour is usually the larger half of the bill.

OEM or aftermarket for a garbage disposal

Paying OEM for everything is waste. Saving on the wrong part costs you the repair twice.

Splash guards, stopper plugs and discharge gaskets are generic and cheap; buy on fit, not brand. Mounting assemblies should match the original brand, because the sink flange, snap ring and mounting ring are a matched set and mixing them is how a slow leak under the sink starts.

Call the manufacturer before you buy anything. A covered repair costs nothing, and fitting a part yourself first can complicate the claim.

Next steps

Not sure the garbage disposal is worth the part?

Check what it is still worth before you spend. The Appliance Blue Book takes its age, brand tier and condition and tells you whether a repair still makes sense — or points you at someone local who can quote the job properly.

Part prices are our own editorial estimates of typical retail ranges for the part alone. They are not quotes, they exclude labour, and they vary by brand, model year and stock. Shipping and returns terms are those each supplier publishes and can change without notice. Always verify part compatibility with your specific model number before purchasing, and disconnect power before any inspection.
