5 Signs It’s Time To Replace Your Garbage Disposal

Your garbage disposal handles a lot of daily work, and most homeowners only notice it when something feels off. If you’ve been hearing strange sounds, dealing with odors that won’t quit, or hitting the reset button more often than usual, these are not random events. They signal that the appliance may be reaching the end of its useful life. And, you are probably wondering whether it’s time to replace the unit or just call for a repair.

Knowing the specific signs to replace your garbage disposal can save you from a surprise water mess and a larger repair bill. Below are five clear indicators that a new unit is the smarter next step, along with guidance on how home warranty coverage can handle the cost.

For peace of mind when your disposal unit acts up, consider getting a home warranty price quote to cover the costs of repair and replacement down the line.

How long do garbage disposals last?

Garbage disposals can last up to 12 years if the appliance is properly maintained.

According to the International Association of Certified Home Inspectors (InterNACHI), this estimate reflects typical household use. Lifespan can vary based on maintenance practices, usage frequency, and the types of food waste processed by the unit.

Running your unit regularly with cold water can help wash out any bits and particles that would otherwise block the piping beneath your kitchen sink.

How to Know When to Replace Your Garbage Disposal

Of course, when the appliance has problems, it can’t do its job. So, how do you know if it is in bad shape or broken? Below are five ways to tell when it’s time to change your garbage disposal.

1. Strange or unusual noises.
Because the unit has moving parts, any peculiar or new noises can be an indicator of a serious problem. Shine a flashlight down your drain to check for anything that may be blocking the unit. A sneaky piece of silverware or a small dish can easily result in unusual sounds from the unit.

If you find something, carefully remove it and test the disposal. If you’re not able to find anything and still hear abnormal sounds, it’s time to call in a professional or consider a replacement.

2. It has a bad smell that won’t go away.
Old food and waste are prone to bad odors, but through proper use of a functioning unit, this shouldn’t be a problem. If odors persist even though you’ve thoroughly rinsed and run your garbage disposal, there may be stubborn particles trapped in the unit that refuse to budge.

In most instances, you can call out a professional to remove these trapped particles. However, if you’re running an older disposal – 15 years or more – it may be time to swap it out.

3. Your unit won’t turn on.
When the appliance won’t turn on, there may be a serious problem with the unit itself. Start by pressing the reset button on the unit to see if that gets it going again. You can also check the circuit breaker in your home’s electrical panel.

If none of these troubleshooting methods resolve the issue, there’s a good chance you’ll need to call in someone to give it a serious look.

4. Water leaking from the main housing
Nothing lasts forever. With kitchen disposals, you’ll usually be looking anywhere from eight to fifteen years before you’ll need to replace the unit.
Over time, the disposal may develop cracks or even spring a leak. When this happens, you’ll likely need to replace the unit, as a repair wouldn’t be worth your money.

5. You’re frequently pressing the reset button on the unit.

The reset button exists for occasional use, not regular operation. If you’re pressing it every few days or every week, the motor inside the unit is losing strength. The reset is compensating for a motor that can no longer complete its cycle reliably.

Pressing the reset button is something that should be done seldom, so pay attention to how often you’re doing it. A healthy disposal rarely needs it. Frequent resets in a unit are one of the clearest signs to replace your garbage disposal.

If replacement appears to be the best option, understanding the expected expense can help you plan ahead. Read our guide, “Cost to Replace Garbage Disposal: What to Expect”, to learn about typical replacement costs and factors that influence pricing.

Frequently Asked Questions

Is a leaking garbage disposal always worth replacing rather than repairing?

Not always, but leaks from the main housing body usually signal internal cracking that repair cannot fix long-term. Leaks at the drain connection or dishwasher inlet may be a simpler fix. If the unit is over eight years old and leaking at the body, replacement is the more cost-effective path.

How much does it cost to replace a kitchen disposal?

A standard replacement costs between $150 and $400 for parts and professional plumbing labor.

Why does my garbage disposal keep clicking off or resetting?

Your unit is likely overheating due to a failing motor, a hidden flywheel jam, or degraded internal electrical wiring components.

Can I use chemical drain cleaners in my garbage disposal unit?

No, harsh chemical drain cleaners can corrode the plastic and metal internal mechanisms of your disposal unit, causing permanent leaks.

Why is my kitchen disposal humming but not grinding?

A humming sound often indicates that power is reaching the unit, but the grinding mechanism is jammed or failing. This issue should be addressed promptly to prevent motor damage.

What should not go into the disposal?

Grease, cooking oil, bones, coffee grounds, eggshells, fibrous vegetables, and starchy foods can damage the unit or cause clogs. Avoiding these materials can help extend disposal lifespan.

How often should I clean my garbage disposal?

Cleaning every one to two weeks can help reduce odors, prevent buildup, and maintain performance.
