Garbage Disposal Humming But Not Working: Motor Problems Explained

When the Humming Means Trouble


You flip the switch, and instead of grinding food waste, your garbage disposal humsβ€”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 panicβ€”Fair Appliance Repair Service is here to help you understand what's happening and how to deal with it safely.


Why Is Your Garbage Disposal Humming But Not Working?


1. Jammed Flywheel or Impeller


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:


πŸ‘‰ Humming sound when switched on


πŸ‘‰ No grinding noise


πŸ‘‰ The reset button may have popped out.


πŸ› οΈ Solution: Turn off the unit and use an Allen wrench to rotate the flywheel manually from underneath the disposal unit.


2. Faulty Motor or Motor Capacitor


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:


πŸ‘‰ You've already reset it, but nothing changes


πŸ‘‰ It's not jammed, but it's still not working.


πŸ‘‰ The hum lasts, and then the unit shuts off


πŸ› οΈ Solution: Depending on the age and brand, you may need to replace the motor or the entire unit.


3. Overheating or Thermal Overload


When the garbage disposal overheats, it automatically shuts off for safety. However, the residual hum may remain briefly.


πŸ› οΈ Solution:


πŸ‘‰ Unplug the unit


πŸ‘‰ Let it cool for 15-20 minutes.


πŸ‘‰ Press the red reset button underneath


πŸ‘‰ If it continues humming without working, the motor may have burned out.
