Garbage Disposal Not Working? Here's What to Do

What You’re Experiencing

Your garbage disposal is doing one of three things: it’s humming but the blades aren’t spinning (jammed), it’s completely silent when you flip the switch (dead), or it’s leaking from the bottom, side, or connection point. In Atlanta homes, disposals tend to see heavy use year-round thanks to frequent cooking and entertaining, and the area’s moderately hard water can accelerate mineral buildup inside the unit.

Common Causes

1. Jammed Impeller (Humming but Not Spinning)

Something hard — a bone, fruit pit, or utensil — is wedged between the impeller plate and the drain housing. The motor hums because it has power but can’t turn. DIY fix: free (with an Allen wrench).

2. Tripped Reset Button

Garbage disposals have an overload protector (a small red or black button on the bottom). When the motor overloads, it trips. DIY fix: free (press the reset button).

3. Tripped Circuit Breaker

The disposal runs on a dedicated circuit. If the breaker trips, it appears completely dead. DIY fix: free (flip the breaker).

4. Failed Motor

If the reset button clicks but the motor won’t start, or you smell a burning odor, the motor has burned out. Disposals typically last 8–12 years. Replacement cost: $150–$350 installed.

5. Leaking Seals or Connections

Leaks from the top flange (sink connection), side (dishwasher hose), or bottom (internal seal) indicate worn gaskets or corrosion. Bottom leaks usually mean it’s time for replacement. Repair: $75–$200. Replacement: $150–$350.

Brand-Specific Issues

InSinkErator

InSinkErator disposals are the most common brand in Atlanta kitchens. The Badger and Evolution series use a hex wrench slot on the bottom for manual unjamming. If your Evolution model shows a red status light, consult the user manual for specific error codes. InSinkErator units have a shorter reset cycle — wait 5 minutes before pressing the reset button for best results.

Moen

Moen disposals feature a Vortex motor that is less prone to jams but more sensitive to hard objects. If your Moen disposal hums and won’t reset, there may be a broken internal flywheel — a repair that typically requires professional replacement of the entire unit.

Waste King

Waste King disposals use a continuous-feed design with high-speed motors (typically 2,800 RPM vs. 1,725 for InSinkErator). They jam less often but are louder and more likely to trip the breaker. If your Waste King unit is leaking from the bottom, the internal seal has failed and replacement is more cost-effective than repair.

DIY Checks Before Calling a Pro

Check 1: Press the Reset Button

Look at the bottom of the disposal unit under the sink. Press the small red or black button firmly. If it clicks, try running the disposal again.

Check 2: Use the Allen Wrench

Insert a 1/4-inch Allen wrench into the hex hole on the bottom of the disposal. Turn it back and forth to free the jammed impeller. Remove any debris through the sink opening with pliers — NEVER put your hand in the disposal.

Check 3: Check the Breaker

Go to your electrical panel and find the disposal circuit. Flip it off and back on.

Check 4: Test the Switch

If the disposal is silent and the breaker is fine, the wall switch may be faulty. Test by listening for any hum when activated.

Safety Precautions

Garbage disposals can cause serious injury if handled incorrectly. Follow these warnings before attempting any inspection or repair:

• Never put your hand inside the disposal. Even when the unit is off, blades and impellers are sharp. Use pliers or tongs to retrieve objects.
• Always disconnect power first. Turn off the wall switch AND unplug the unit under the sink (or flip the breaker) before doing any work.
• Never pour chemical drain cleaner into a disposal. It corrodes internal components and creates toxic fumes when the motor runs. Use ice cubes and salt for cleaning instead.
• Keep water running. Always run cold water before, during, and 15 seconds after using the disposal to flush debris through the drain line.

When to Call a Professional

• The disposal won’t respond after reset and breaker check
• There’s a burning smell from the motor
• Water is leaking from the bottom of the unit (internal seal failure)
• You need a new disposal installed
• The disposal is connected to a dishwasher and both are having drainage issues

Questions to Ask Your Technician

When you call a repair professional for your garbage disposal, these questions help you get accurate pricing and avoid surprises:

• Is it more cost-effective to repair or replace my disposal? Disposals under $200 are almost always cheaper to replace than repair.
• What horsepower disposal do you recommend for my household? A family of four in Atlanta typically needs at least a 3/4 HP unit.
• Is the diagnostic fee waived if I proceed with the repair? Most Atlanta-area technicians waive the $50–$100 diagnostic fee when you approve the work.
• Do you handle the plumbing connections, including the dishwasher drain line? Not all appliance techs do plumbing — confirm before booking.
• What warranty do you offer on the installation? Look for at least a 90-day labor warranty in addition to the manufacturer’s parts warranty.
