Garbage disposals are a convenient addition to any kitchen, making cleanup quicker and easier. However, when your garbage disposal is not working, it can disrupt your routine and lead to frustration. Whether your unit has stopped working entirely or is only partially functioning, understanding the common issues can help you determine whether you can fix it yourself or if it’s time to call a professional.
In this guide, we’ll explore why your garbage disposal may have stopped working, troubleshooting tips, and preventative maintenance practices to keep your unit running smoothly.
Common Reasons a Garbage Disposal Stops Working
When your garbage disposal isn’t functioning properly, one of these issues is likely the culprit:
1. Electrical Issues
Tripped Button: Most garbage disposals are equipped with a reset button located underneath the unit. If the disposal has overheated or encountered a minor issue, pressing the reset button can often solve the problem.
Faulty Wiring or Circuit Breaker: If the disposal isn’t receiving power, check the circuit breaker and wiring. This could indicate an electrical issue rather than a mechanical one.
2. Jammed Blades
Humming Noise: A humming sound often indicates the blades are jammed by food debris, bones, or even non-food items like utensils.
What Not to Put in the Disposal: To avoid jams, never dispose of bones, fibrous vegetables (e.g., celery, corn husks), coffee grounds, eggshells, or grease in the disposal. These items are notorious for causing clogs and damage.
3. Worn-Out Motor
Over time, the motor may wear out, especially in older units. If the disposal isn’t turning on and you’ve ruled out electrical issues, the motor may have reached the end of its lifespan.
When to Replace the Unit: Most garbage disposals last 8–15 years, depending on usage and maintenance. If yours is nearing this age and frequently malfunctions, replacement is often more cost-effective than repeated repairs.
4. Clogs in the Sink Drain
Food debris, grease, or other blockages in the drainpipes can cause water to back up and make the disposal appear non-functional. Regular cleaning of your pipes can help prevent this.
Steps for Troubleshooting Your Garbage Disposal
If your sink disposal isn’t working, follow these steps before calling for professional help:
Step 1: Check the Power
- Ensure the unit is securely plugged in.
- If it’s plugged in but still not working, inspect the circuit breaker or press the reset button.
Step 2: Look for Jams
- Turn off the power to the disposal.
- Use an Allen wrench (hex key) to manually turn the blades and clear any blockages.
Step 3: Clear Drain Blockages
Use a plunger or drain snake to dislodge any clogs. Avoid harsh chemical cleaners, as they can damage your pipes and the disposal unit.
When to Call a Plumber
If your garbage disposal still isn’t working after troubleshooting, it may require professional repair or replacement. A plumber can diagnose the issue and determine whether your disposal can be fixed or if you need a new one.
Sometimes, a DIY approach isn’t enough. Call a professional if:
- The motor is burnt out.
- There are persistent electrical issues.
- The unit requires replacement, especially if it’s old or beyond warranty coverage.
Preventative Maintenance Tips for Garbage Disposal
To ensure your garbage disposal remains in good working condition:
- Use a Traditional Garbage Bin: Reserve the disposal for small amounts of food waste during cleanup. This reduces strain on the motor and blades.
- Avoid Using the Disposal with a Septic Tank: Garbage disposals can overload a septic tank, leading to clogs and costly repairs.
- Clean Regularly:
- Use a mixture of baking soda and vinegar monthly to clean the disposal and eliminate odors.
- Run cold water while using the disposal to help solidify grease and flush waste properly.
- Know What Can and Can’t Go in the Disposal: As mentioned, avoid disposing of bones, grease, or fibrous items.
Typical Warranty Coverage
Most garbage disposals come with a warranty that covers defects in materials or workmanship, typically lasting 1–10 years depending on the brand and model. Warranties often exclude damage caused by improper use (e.g., putting non-food items in the disposal) or lack of maintenance. Check your unit’s warranty details for specifics and consider a professional repair if the problem falls under coverage.
Conclusion
A garbage disposal not working can be inconvenient, but understanding the common issues and how to troubleshoot them can save you time and money. Whether it’s a tripped button, a jammed blade, or a worn-out motor, this guide has outlined practical steps to resolve the problem.
Remember, proper maintenance is key to prolonging the life of your disposal. Use a traditional garbage bin whenever possible, clean the unit regularly, and avoid overloading it with unsuitable items.
If your disposal is beyond repair, or you’re unsure of the problem, don’t hesitate to consult a professional plumber. A properly functioning garbage disposal is essential for a smooth-running kitchen!
