Troubleshooting Your Garbage Disposal: Why It Stopped Working and How to Fix It
If your garbage disposal has suddenly stopped working, you're not alone. This common household issue can be frustrating, but don't worry, it's often easy to fix. In this guide, we'll explore the most common reasons why your garbage disposal might have stopped working and provide simple, step-by-step solutions to get it up and running again.
Understanding Your Garbage Disposal
Before we dive into troubleshooting, let's quickly understand how a garbage disposal works. It's essentially a motorized device that shreds food waste into small particles that can pass through your plumbing system. It's connected to your sink's drain and is activated by a switch, usually located near the sink.
Common Reasons Why Your Garbage Disposal Stops Working
- Overload or Jam: The most common reason for a garbage disposal to stop working is that it's overloaded or jammed.
- Power Issues: There could be a power problem, either at the disposal itself or at the circuit it's connected to.
- Faulty Switch: The switch that turns your garbage disposal on and off might be faulty.
- Broken Parts: Over time, parts of the garbage disposal can wear out or break, causing it to stop working.
Step-by-Step Troubleshooting Guide
1. Check for Power
First, ensure that your garbage disposal is receiving power. Check the circuit breaker to see if the switch has tripped. If it has, flip it back to the 'on' position. If the switch trips again, there might be a more serious electrical issue at play, and you should contact a professional electrician.

2. Reset the Disposal
Garbage disposals have a reset button located on the bottom or side of the unit. If your disposal has stopped working, try pressing this button to reset it. If the button is stuck in the 'on' position, you might need to use an Allen wrench to turn it clockwise until it clicks back into place.
3. Check for a Jam
If your disposal is humming but not turning, it's likely jammed. To fix this:
- Turn off the power to the disposal at the circuit breaker.
- Use an Allen wrench (usually provided with the disposal) to turn the flywheel in both directions. This should free up any jammed debris.
- Once the jam is cleared, turn the power back on and test the disposal.
4. Inspect the Flywheel
If the flywheel is broken, you'll need to replace it. This is a more involved process that might require professional help. If you're comfortable with DIY repairs, you can find replacement flywheels online or at hardware stores.

5. Check the Switch
If your disposal isn't turning on at all, the problem might be with the switch. Test the switch by plugging in a small appliance, like a lamp, to ensure it's working. If the switch is faulty, you'll need to replace it.
Preventing Future Issues
To prevent your garbage disposal from stopping working in the future, follow these tips:
- Run cold water continuously while using the disposal and for a few seconds after turning it off.
- Never put non-food items, like utensils or glass, down the disposal.
- Regularly grind ice cubes to help clean the disposal and keep blades sharp.
- Regularly clean the disposal by grinding a mixture of lemon peels and ice cubes, then rinse with cold water.
If none of these troubleshooting steps solve the problem, it might be time to replace your garbage disposal. With proper care and maintenance, a good quality disposal can last for many years, but even the best disposals will eventually wear out.
