FAQs
What typically causes garbage disposal impellers to jam?
The most common culprits are hard food scraps (bones, fruit pits), fibrous materials (celery stalks, corn husks), and non-food items (utensils, bottle caps) that slip into the unit. These objects wedge between the impeller plate and the shredder ring, preventing the plate from spinning. In Lookout Mountain, where many homes sit above tree-lined lots, autumn leaf debris can also make its way into outdoor kitchen sinks and contribute to jams.
How do I know if my disposal in Lookout Mountain has jammed impellers or a burned-out motor?
If you flip the switch and hear a low hum but no grinding noise, the motor is energized but the impeller plate is stuck—classic jam. A burned-out motor, on the other hand, is silent or trips the circuit breaker immediately. Another quick check is to insert an Allen wrench into the hex slot on the bottom of most disposals: if you can’t turn it in either direction, the impellers are jammed. If it spins freely but the unit still won’t start, the motor or internal wiring may be at fault.
Is it safe to unjam the disposal myself, or should I call a professional plumber?
You can attempt a basic reset and manual unjamming—turn off power at the breaker, press the red reset button on the base, and use an Allen wrench to rotate the flywheel. However, avoid sticking hands or makeshift tools inside the grinding chamber. If the unit still hums or trips the breaker, or if you smell burning, shut it off and call a licensed plumber. Improper DIY attempts can damage the motor or void the manufacturer’s warranty, and plumbing codes in Lookout Mountain require electrical safety compliance.
How quickly can a technician reach my Lookout Mountain home for jammed-impeller repairs?
Because Lookout Mountain is only 15–20 minutes from our main Chattanooga dispatch center, we offer same-day service on most calls received before 2 p.m. For after-hours or weekend emergencies, we provide a 24/7 on-call plumber who can usually arrive within 60–90 minutes, weather and traffic permitting. During peak tourist seasons the roads can be busier, but we prioritize disposal jams because they can halt kitchen operations and cause sink backups.
If my disposal is more than 10 years old, is it worth repairing the jam or should I replace the unit?
Most jams are inexpensive to fix—usually a service call plus minor parts. However, disposals over 10 years old may have worn bearings, seals, and motors that make recurrent jams more likely. If the unit shows rust, leaks, or frequent resets, replacement is often more economical. Newer ENERGY STAR® models grind more efficiently and use less water and power. We can assess on-site and provide a repair-versus-replace quote so you can make an informed choice.
What preventive steps can I take to avoid future impeller jams?
1. Feed small amounts of food waste gradually, running cold water the entire time. 2. Avoid hard or fibrous items—compost them instead. 3. Cut large scraps into smaller pieces before grinding. 4. Once a week, grind a tray of ice cubes with a splash of vinegar or lemon to scour residue from the impeller plate and freshen odors. 5. Keep silverware stowed away from the sink basin. 6. Have a plumber perform an annual inspection; they’ll tighten mounting bolts, check for leaks, and verify electrical safety to keep your disposal jam-free.
