Garbage Disposal Jammed? Here’s How to Fix It
If your garbage disposal is jammed and only making a humming noise, you’re not alone. This is one of the most common kitchen issues homeowners run into, and in many cases, it can be fixed in just a few minutes.
That humming sound usually means the motor still has power, but something inside is preventing the disposal from spinning. Before you assume it needs to be replaced or schedule a repair, you may already have the tools at home to fix it yourself.

Why Garbage Disposals Get Jammed
A jammed garbage disposal is usually caused by something blocking the grinding chamber or restricting the internal components.
Common causes include:
Food scraps packed too tightly
- Grease or debris buildup
- Small utensils or foreign objects dropped inside
- Fibrous foods like celery, corn husks, or peels
- Internal parts sticking after long periods without use
The good news is that many of these issues can be cleared without major repairs.
How to Fix a Jammed Garbage Disposal
Most garbage disposals are designed with a manual release mechanism on the bottom of the unit. This allows you to manually turn the disposal and break the jam free.
1. Turn Off the Power
Before doing anything, make sure the disposal is switched off. For added safety, turn off the breaker as well.
2. Locate the Bottom Access Point
Look underneath your sink at the bottom of the garbage disposal. Most units have a small slot designed for a disposal wrench or hex key.
3. Use the Proper Tool
If you still have the garbage disposal wrench that came with the unit, use that first.
If not, you may already have another tool at home that can work depending on the model.
Common household tools may include:
- Allen wrenches
- Certain drill bits
- Paddle bits
- Pliers for grip and leverage
The key is using something that fits securely and allows gentle control.
4. Rotate the Mechanism
Turn the tool back and forth slowly to help free the jam. You may feel resistance at first, then the disposal should begin moving more easily.
5. Test the Disposal
Restore power and briefly test the unit while running cold water.
If it spins normally again, the jam has likely been cleared.
Important Safety Tips
Whenever working on a garbage disposal:
- Never put your hand inside the unit
- Always disconnect power first
- Use tools carefully
- Stop immediately if you smell burning
- If the motor overheats, allow it to cool before retrying

No. If your disposal is humming but not spinning, you should turn it off right away. Letting it run in this state can overheat the motor and cause permanent damage.
