How Do You Fix a Garbage Disposal?
Most garbage disposal problems trace to a tripped reset button, a jam, or motor failure. A licensed Oklahoma plumber explains the safe way to fix each one.
How to Fix a Garbage Disposal: Essential Steps from a Licensed Plumber
Fixing a garbage disposal typically involves resetting the unit, clearing jams, or addressing mechanical failures. Most garbage disposal problems in Edmond and Oklahoma City homes stem from overloading, foreign objects, or electrical issues. As a licensed plumber, I recommend starting with the simplest solutions first: check if the disposal has tripped its reset button located on the bottom of the unit, ensure the circuit breaker hasn’t flipped, and verify the wall switch is functioning properly. If the disposal hums but doesn’t spin, you likely have a jam that needs clearing. Never put your hand inside a disposal—instead, use the Allen wrench method or a disposal turning tool to safely dislodge obstructions.
How Do You Troubleshoot a Garbage Disposal That Stopped Working?
When your garbage disposal stops working, systematic troubleshooting identifies the issue quickly. First, turn off the power at the breaker box for safety. Look underneath the disposal unit for a small red or black reset button and press it firmly—this resolves many issues caused by overheating or overloading. If pressing reset doesn’t work, check the circuit breaker in your electrical panel.
For a humming disposal that won’t turn, you have a jam. Locate the hex-shaped hole on the bottom center of the disposal and insert a 1/4-inch Allen wrench. Turn it back and forth several times to manually rotate the grinding plate and free the obstruction. Many disposals come with this wrench attached to the unit. Alternatively, use a wooden spoon or broom handle inserted from the top to push against the impeller blades (with power off). Once freed, remove any visible debris, restore power, run cold water, and test the disposal.
When Should You Replace a Disposal Instead of Repairing It?
Some disposal problems require professional assessment. If you notice persistent leaking from the housing, frequent tripping despite proper use, or complete motor failure, replacement may be more cost-effective than repair. Oklahoma’s hard water can accelerate corrosion in disposal components, sometimes making older units beyond economical repair. At Triple Play Home Services, we’ve seen that disposals older than 10-12 years often develop multiple issues simultaneously.
Safety Precautions and Professional Help
Always disconnect power before attempting any garbage disposal repair. Never use chemical drain cleaners in disposals, as they damage seals and pipes while creating dangerous conditions. Avoid putting fibrous materials like celery, corn husks, or potato peels down your Edmond home’s disposal, as these commonly cause jams.
If basic troubleshooting doesn’t resolve your disposal issue, or if you’re uncomfortable working with electrical appliances and plumbing connections, professional help ensures safe, lasting repairs. Complex problems like internal seal failures, motor bearing issues, or mounting assembly problems require specialized tools and expertise.

Frequently asked questions
- Why is my garbage disposal humming but not spinning?
- A humming disposal almost always means the grinding plate is jammed. Turn off the power, insert a 1/4-inch Allen wrench into the hex hole on the bottom of the unit, and work it back and forth to free the obstruction. Never reach inside the disposal with your hand.
- Where is the reset button on a garbage disposal?
- Look underneath the unit, on the bottom of the disposal housing, for a small red or black button. Press it firmly after the motor overheats or overloads. If it trips again right away, check the circuit breaker — repeated tripping can signal a failing motor.
- When should I replace a garbage disposal instead of repairing it?
- Replace it when you see persistent leaks from the housing, frequent reset trips despite proper use, or complete motor failure. Oklahoma's hard water corrodes internal components, so disposals older than 10 to 12 years often develop several problems at once and usually aren't worth repairing.
- What should never go down a garbage disposal?
- Keep grease, celery, corn husks, potato peels, and other fibrous foods out of the disposal — they're the most common causes of jams. Skip chemical drain cleaners too; they damage seals and pipes. If a clog keeps returning, Triple Play Home Services can help at (405) 500-5333.
