Garbage disposal repair: what you fix, what you replace

Most “repair” is a jam, a reset, or power. The rest is a new unit. Do not rebuild a cracked drum.

DIY — jam, clog, reset, power, smell

Clear a jam from below with a 1/4″ hex key. Clear a drain-side clog at the P-trap before you blame the motor. Press the red reset. Confirm the wall switch and the breaker. Scrub a rotten smell off the splash guard before you buy parts. Fish out whatever is rattling and snug a loose mount before you blame a new noise on the motor. If the panel or GFCI opens when you run it, clear a jam and cool the motor before you assume the unit is dead. Those cover the jobs that are actually repairable at the sink. This page is the hub for garbage disposal repair: pick the symptom, then decide keep or replace.

Replace — do not keep repairing

Buy a new disposal if any of these are true:

• Cracked housing or a leak from the body, not a joint
• Worn lugs — food spins, nothing grinds, jams keep coming back
• Squealing or grinding from the motor with an empty chamber (see noise)
• The unit is older than 8–12 years
• A body leak you already dried and watched return

Three replacement lanes, no reviews. Then DIY vs hire for install.
