While unplugging your garbage disposal and plugging it back in may help, most units have an actual reset button, a bright red switch found on the underside of your unit. If your garbage disposal needs resetting, you may notice this button sticking out about a quarter of an inch from the surface of the unit, with which it’s usually flush. Simply depress this reset button to reset the unit, and then test to ensure it’s working about 10 minutes later.

Never put glass in the garbage disposal. It can damage your disposal or eject shards of glass out of the disposal and cause injury. If you get broken glass in your garbage disposal, turn it off and cut the power from the breaker, use a tool like pliers or tongs to remove the glass, and use a wet-dry vacuum to remove the remaining glass pieces. If you can’t access the disposal safely, call a garbage disposal repair pro.

Most garbage disposals have a reset button that can be triggered with a tool as simple and accessible as your index finger. That said, if you need to perform a more in-depth troubleshooting step, like manually moving the arms inside the unit or rotating the impeller plate, a hex wrench is the most common tool you’ll need. Most garbage disposals come with a hex wrench.

Whether it's worth repairing your garbage disposal depends on its age and the specific problem. Generally, if the unit is eight years old or younger, repair is a good option. For minor issues like a bad seal or a simple jam, a repair can be inexpensive, sometimes under $10. However, if the motor is broken (a repair that can cost $150 or more) or the unit is getting old, it's often more cost-effective to replace the entire disposal.
