If your garbage disposal has suddenly stopped working, don’t panic—it may not need to be replaced. In many cases, a simple jam is the culprit, and you can fix it yourself using the small “S”-shaped hex wrench that came with the unit. Most homeowners don’t realize this tool even exists until they read the manual—or stumble across a helpful article like this one.
As a handyman, I often get calls about “broken” disposals that just need a quick turn with this little tool. So here’s how you can try fixing it before calling in the pros.
Step 1: Safety First – Unplug the Unit
Before you do anything, unplug the garbage disposal or turn off the power at the breaker box. Never, ever reach into a disposal with your hand or tool while it’s connected to power. Even if it’s off, safety comes first.
Step 2: Locate the Hex Hole Underneath
Crawl under the sink and look at the bottom of the garbage disposal unit. Right in the center, you’ll see a small hex-shaped hole. This is where the “S” wrench fits. Some disposals come with this tool attached underneath, but if yours is missing, a standard 1/4-inch Allen wrench will work just fine.
Step 3: Insert the Wrench and Turn
Insert the wrench into the hole and gently try to turn it back and forth. If it’s jammed, it might be stiff at first, but don’t force it too hard. Work it slowly until you feel it loosen up and spin freely. This movement helps dislodge whatever is stuck between the blades.
Step 4: Check Inside (Carefully!)
After you’ve freed the blades, use tongs or pliers (not your fingers!) to peek inside the top of the disposal. You might find a bone, a spoon, or some other item that caused the jam. Remove anything you can see.
Step 5: Restore Power and Test
Once you’re confident the jam is cleared, plug the unit back in or flip the breaker on. Then test it by running cold water and switching the disposal on. If it hums or runs sluggishly, turn it off immediately and repeat the process.
When to Call a Pro
If the disposal still doesn’t run—or you hear a loud humming without the blades moving—it might be time to call a handyman or replace the unit altogether. Motor issues and electrical faults aren’t DIY-friendly and are better handled by a professional.
Final Tip from a Handyman
Always keep that little “S” wrench in a drawer under the sink or taped to the side of the disposal. It can save you time, money, and the headache of calling someone out for a 5-minute fix.
