Understanding How a Garbage Disposal Works
Your garbage disposal is the unsung hero of the kitchen — breaking down food waste so it flows smoothly through your plumbing. When it jams, it can throw your whole day off.
Here’s how it normally works:
- Motor Activation: Flipping the switch powers a small electric motor.
- Grinding Process: The motor spins impellers that shred food into fine particles.
- Water Flush: Cold water carries those particles safely through your pipes.
When the system jams, that steady hum without rotation means something’s blocking the blades or motor.
Common Reasons Your Garbage Disposal Is Jammed
Several culprits can cause a jam or humming sound:
- Foreign Objects: Forks, small bones, bottle caps, or other items can get lodged.
- Overloading: Feeding too much food waste at once can stall the motor.
- Lack of Water: Running the disposal dry can lead to buildup and blockage.
- Dull Blades: Over time, the grinding mechanism loses its edge, struggling with normal debris.
Safety First: Before You Do Anything
⚠️ Always prioritize safety before repairs.
- Turn Off Power: Unplug the disposal or switch off the circuit breaker.
- Never Reach In: Don’t stick your hand in the drain — even when the power is off. Use tongs or pliers instead.
- Protect Yourself: Gloves and safety glasses can prevent injury.
Tools You’ll Need
To fix a jammed garbage disposal, gather these essentials:
- ¼-inch Allen wrench (hex key) – for turning the flywheel.
- Needle-nose pliers or tongs – to pull out obstructions.
- Flashlight – for visibility under the sink.
- Bucket or towel – to catch drips or debris.
Step-by-Step: How to Fix a Stuck Garbage Disposal
- Cut Power Completely: Ensure it’s unplugged or switched off at the breaker.
- Inspect Inside: Use a flashlight to identify visible debris. Remove it gently with tongs.
- Turn the Flywheel:
- Look underneath the disposal unit for a small hex-shaped opening.
- Insert the Allen wrench and turn it back and forth.
- You’ll feel resistance—keep working it until the wheel moves freely.
- Reset the Disposal: Press the red reset button on the bottom.
- Restore Power & Test: Reconnect the power and run water as you flip the switch. The unit should hum briefly, then grind normally.
Keep Your Garbage Disposal Running Smoothly
Prevent jams before they happen with these easy maintenance tips:
- Always use cold water. Hot water can cause grease to solidify and stick to the blades.
- Avoid fibrous or hard waste. Keep out bones, fruit pits, and peels like corn husks or potato skins.
- Clean every two weeks. Run ice cubes through it with cold water for a quick blade refresh.
- Use a degreaser periodically. Keeps fat buildup from slowing the motor.
- Snake the drain every 2 years. A quick, affordable way to keep pipes clear.

1. Why does my garbage disposal just hum when I turn it on?
A humming sound usually means the motor is working but the flywheel is jammed. Use an Allen wrench to free it manually.

No. Hot water can make grease congeal and worsen clogs. Always use cold water.
3. What shouldn’t I put down my disposal?
Avoid fibrous foods (celery, corn husks), starchy items (pasta, rice), and any kind of grease or oil.
4. How often should I clean my garbage disposal?
Every 1–2 weeks is ideal to prevent odor and buildup.
