InSinkErator Garbage Disposer Parts

InSinkErator disposers are built to grind food waste reliably, but even the toughest units eventually need replacement parts. When your Badger or Evolution model starts leaking, jams, or loses grinding power, the right OEM part gets you back to a working sink fast. Common failures include worn grinding chambers, tripped reset switches, and mounting hardware that loosens over time.

The most common fix is simpler than you'd think — a tripped thermal overload reset switch often stops the disposer cold. Jam busters, splash guards, and replacement power cords are also frequent repairs. Browse InSinkErator disposer parts by model to find exactly what you need, or use our model number lookup below.

• Disposer won't run or hums: Reset switch tripped (thermal overload); press red button on bottom of unit first
• Poor grinding or weak discharge: Worn grinding parts; replace grinding chamber assembly
• Leaks at sink flange: Mounting rings loose or gasket failed; reset with wrench or replace flange kit
• Jammed disposal: Use jam buster key or Allen wrench; remove bone/foreign object before restarting
• No power to unit: Check power cord; replace if frayed or burnt

InSinkErator Garbage Disposer FAQs

Why did my InSinkErator disposer stop working?

The most common reason is a tripped thermal overload reset — press the red reset button on the bottom of the unit. If that doesn't work, check that the breaker hasn't tripped. If the motor hums but won't turn, something's jamming the grinding chamber. Turn off power, use a jam buster key or Allen wrench to free the jam, remove the obstruction, then try again. If it still won't run after reset, the motor or control switch may have failed.

How do I find my InSinkErator model number?

The model number is stamped on the underside of the disposer unit, on the collar that mounts under the sink. Look for a label that starts with "BADGER" or "EVOLUTION" followed by a number (e.g., BADGER 5 or EVOLUTION 200). Write down the complete model number — it's required for getting the exact replacement parts for your unit.

What's the difference between InSinkErator Badger and Evolution disposers?

Badger models are entry-level, durable disposers designed for standard food waste. Evolution models offer higher horsepower, faster grinding, and quieter operation — they're a step up in performance and features. Both use similar mounting hardware and basic parts, but control switches and grinding chambers differ. Always use your model number to confirm part compatibility.

Can I replace just the grinding chamber on my disposer?

Yes. If your InSinkErator is grinding slowly or producing weak discharge, the grinding parts (impeller and chamber) can wear down. Replacement grinding chamber assemblies are available — they're one of the most cost-effective repairs you can do. Confirm your model number to ensure you get the right fit, as chamber designs vary between Badger and Evolution lines.

Find the Model Number on Your InSinkErator Garbage Disposer

On most InSinkErator garbage disposers, the model number is stamped on the underside of the unit, around the mounting collar beneath the sink. Use a flashlight and wipe away grime if needed, then record the complete number, including the BADGER or EVOLUTION name and any digits that follow it. Type it into our model number lookup and the catalog narrows to parts made for your unit. This model number applies to the entire disposer, so it filters the full selection of associated parts, from mounting hardware and gaskets to switches and grinding parts. You get a faster, more accurate match without guessing between similar InSinkErator models.
