FAQs
What causes my garbage disposal to make a loud growling or grinding noise?
A growling sound usually means something inside the grinding chamber is preventing the blades and flywheel from spinning freely. Common culprits include silverware, bone fragments, fruit pits, or excess fibrous food such as celery or corn husks. If nothing is jammed, the noise can point to worn-out bearings, a loose mounting ring, or an aging motor that is beginning to fail. Our technicians start with a visual inspection and manual rotation test, then check electrical load and bearing wear to pinpoint the exact cause.
Is it safe to keep running the disposal when it’s growling, or should I shut it off right away?
Turn the unit off immediately. Continuing to run a disposal that is growling can overheat the motor, shear the impellers, and damage your plumbing trap. Always cut power at the wall switch or breaker panel before putting your hand or a tool anywhere near the opening. Once the unit is off, look inside with a flashlight—never with your fingers—to see if an object is lodged. If you can’t remove the obstruction safely or the noise persists after clearing it, schedule service to avoid a complete motor burnout.
Can I fix a growling garbage disposal myself, and what’s the safest DIY approach?
You can try a basic jam-clearing procedure: 1) Switch off power at the breaker. 2) Insert a ¼-inch Allen (hex) key into the bottom flywheel socket and turn it back and forth to free the impellers. 3) Use tongs or pliers to remove any visible debris from the chamber. 4) Press the red reset button on the underside, restore power, and test the unit with running cold water. If the growling returns, the issue is likely internal wear or motor failure that requires professional tools and replacement parts. Avoid using chemical drain cleaners or forcing the flywheel; these steps can warp seals and void warranties.
How quickly can your Knoxville team repair or replace a growling garbage disposal?
For most homeowners in Knoxville, we provide same-day or next-day service. If you call before noon, our dispatcher can often send a licensed plumber within a 2-hour window. Standard repairs—such as clearing jams, tightening the mounting assembly, or replacing a worn splash guard—take about 45 minutes. Complete disposal replacement typically runs 1–1½ hours, including leak and electrical tests. Emergency after-hours service is also available 24/7 for heavy jams that risk flooding or kitchen downtime.
What does garbage disposal repair cost in Knoxville, including diagnosis of a growling unit?
Our trip and diagnostic fee is $49, which is waived if you proceed with the repair. Simple jam clearances or reset services range from $95–$145. Replacing seals, bearings, or the flywheel generally falls between $180–$250, parts and labor included. If the motor is burnt out, installation of a new, comparably sized disposal runs $325–$475, depending on horsepower and warranty length. We provide upfront, written estimates so you know the exact price before work begins, and all repairs carry a 1-year parts-and-labor warranty.
How can I prevent my garbage disposal from growling in the future?
Run a strong stream of cold water before, during, and 15 seconds after every use; cold water keeps fats solid so they grind and flush away instead of coating the chamber. Feed food scraps slowly to avoid overloading. Avoid fibrous foods (celery, onion skins), starchy items (potato peels), coffee grounds, and expandable foods like pasta or rice. Once a month, grind a tray of ice cubes and a cup of rock salt to scour the impellers, then rinse with a half-cup of baking soda followed by a cup of white vinegar to neutralize odors. Finally, schedule an annual maintenance check—especially for units older than five years—to tighten mounting hardware, test amperage draw, and catch bearing wear before it turns into a growl.
