A disposal that hums without grinding, or does nothing at all, often has a simple cause. A few checks can be made safely with the power off. If they do not solve it, stop there and call.
FIELD NOTE
Safety First
Turn the disposal off at the wall switch. If you can reach the breaker safely, turn that off as well. Never put your hand into the disposal, even when it is off.
If water is leaking near the unit’s electrical connection, do not touch it. Keep clear and call.
FIELD NOTE
If It Hums But Does Not Turn
The motor is likely jammed. Many units have a hex-shaped socket in the center of the bottom. With the power off, insert the hex key that came with the unit and work it back and forth until the motor turns freely.
If you can see an object in the chamber, remove it with tongs or pliers with the power off. Do not use your fingers, and do not push tools into the chamber blindly.
FIELD NOTE
If It Does Not Start At All
Many units have a small reset button on the bottom that trips when the motor overheats or jams. Wait a few minutes, then press it once with the power off. Restore power and test briefly with cold water running.
If the reset keeps tripping, the unit still hums after freeing it, or nothing happens at all, stop trying. The motor, switch, or electrical connection may need attention, and we can check it safely.
