You flip the switch, and instead of grinding food waste, your garbage disposal hums—and that's it. No spinning. No shedding. Just a low humming sound that tells you something's wrong. In most cases, the problem lies in the motor or internal mechanics. But don't panic—Fair Appliance Repair Service is here to help you understand what's happening and how to deal with it safely.
The most common cause of a humming sound is a jammed flywheel. When food particles or debris block the blades from spinning, the motor tries to work but can't rotate the mechanism, hence the hum.
Signs of a jam:
👉 Humming sound when switched on
👉 No grinding noise
👉 The reset button may have popped out.
🛠️ Solution: Turn off the unit and use an Allen wrench to rotate the flywheel manually from underneath the disposal unit.
If the motor's capacitor (which helps start the motor) fails, the disposal may still hum but won't turn. A faulty motor is often the case in older units.
How to tell:
👉 You've already reset it, but nothing changes
👉 It's not jammed, but it's still not working.
👉 The hum lasts, and then the unit shuts off
🛠️ Solution: Depending on the age and brand, you may need to replace the motor or the entire unit.
When the garbage disposal overheats, it automatically shuts off for safety. However, the residual hum may remain briefly.
🛠️ Solution:
👉 Unplug the unit
👉 Let it cool for 15-20 minutes.
👉 Press the red reset button underneath
👉 If it continues humming without working, the motor may have burned out.
👉 Turn off the power at the breaker.
👉 Check for jams using a flashlight and wooden stick (never your hand!)
👉 Use the Allen wrench to rotate the flywheel manually.
👉 Press the reset button
👉 Plug it back in and test.
👉 Still humming? Time to call the pros.
Ignoring humming disposal can lead to motor burnout, electrical issues, or safety risks. What starts as a small issue can become a costly replacement if not addressed early.
