How to Fix a Jammed Garbage Disposal

Overview

A jammed garbage disposal is a common kitchen problem that's usually easy to fix. When a disposal jams, it makes a humming sound but won't turn, typically because something is stuck between the impellers. This guide covers safe methods to unjam your disposal and get it working again.

Why This Matters

Professional repair for a jammed disposal costs $100-$200, but most jams can be fixed in minutes with basic tools. Knowing how to safely unjam a disposal saves money and prevents the inconvenience of a non-working disposal. The fix is simple once you understand the process.

Safety First

Essential Safety Rules

Before starting:

• Turn off power - At circuit breaker or switch
• Never put hand in disposal - Even with power off
• Use tools - Hex wrench or tongs to remove objects
• Check for sharp objects - Be careful when removing items
• Test power is off - Before any work

When to Call a Professional

Call a plumber if:

• Disposal won't unjam - After trying these methods
• Electrical problems - Circuit keeps tripping
• Leaks - Water escaping from disposal
• Unusual sounds - Grinding, scraping when running
• Uncomfortable with the process

Step 1: Turn Off Power

Disconnect Electricity

Critical first step:

1. Locate circuit breaker - For disposal circuit
2. Turn off breaker - Switch to OFF position
3. Or use switch - Under-sink switch if present
4. Verify power is off - Test switch (shouldn't work)
5. Never skip this step - Safety is essential

Step 2: Try Manual Rotation

Use Hex Wrench

Most disposals include a hex wrench:

1. Locate hex socket - Bottom center of disposal
2. Insert hex wrench - Provided with disposal
3. Turn back and forth - Rotate both directions
4. Feel for movement - Should free the jam
5. Remove object - If visible and accessible

If No Hex Wrench

Alternative method:

• Use long-handled tool - Pliers or tongs
• Reach from top - Through drain opening
• Carefully remove - Object causing jam
• Never use hands - Always use tools

Step 3: Remove Obstruction

From Top Opening

If object is visible:

1. Use flashlight - See into disposal
2. Use tongs or pliers - To grab object
3. Pull out carefully - Avoid sharp edges
4. Check for other objects - May be multiple items

Common Jam-Causing Items

What to look for:

• Bones - Chicken, fish, etc.
• Fruit pits - Peach, avocado, etc.
• Utensils - Forks, spoons (rare but possible)
• Fibrous materials - Corn husks, celery strings
• Too much food - Overloaded disposal

Step 4: Test the Disposal

Restore Power and Test

After clearing jam:

1. Remove tools - Clear disposal area
2. Turn on power - Restore electricity
3. Run cold water - Always run water with disposal
4. Turn on disposal - Test if it works
5. Listen for normal sound - Should run smoothly

If Still Jammed

Additional steps:

• Try hex wrench again - May need more force
• Check for multiple objects - May be more than one
• Inspect impellers - May be damaged
• Consider professional - If won't unjam
