If your garbage disposal suddenly stops working and only hums when you flip the switch, you most likely have one of these 2 problems:
Now, first off, the fact that you hear the disposer humming means that you are still getting power to the device, which rules out any electrical supply problems. But something (either a jam or a bad motor) is preventing the blades from churning.
Note: If your disposal motor is at fault, it’s probably more cost-effective to just replace the garbage disposal altogether instead of repairing it.
We’ll show you how to determine which problem you have and what to do next.

What you’ll need:
To determine whether your disposal is jammed, follow these steps:
Note: Always run water while you are testing the disposal. Also, avoid keeping the disposal on for more than a minute at a time to prevent (further) damage to the motor.
Turn the allen wrench back and forth. Then check to see if the disposal runs normally. If the disposal still only hums and water doesn’t drain well, have a professional check for a clog in the P-trap under your sink.
If you’ve determined that your disposal isn’t jammed, you most likely have a disposal motor that needs to be repaired or replaced.
To help you decide whether you should repair or replace your disposal, we’ve included some cost comparisons between the two options.
Keep in mind that higher-end garbage disposal models will cost more to install. But if you want to replace your disposal for a simple, less expensive model, you’re most likely better off replacing the device rather than repairing it.
If your disposal still isn’t working and you’re not sure whether to repair or replace, just contact us.
We’ll send over a professional plumber who can diagnose the problem and give you both repair and replace options.
