Garbage disposal humming but not working

Garbage disposal humming but not working. If you hear a humming sound coming from your garbage disposal but can’t get it to work, don’t sweat it.

We have all of the answers you’re looking for so that you’ll never have to worry about your friend again.

Perhaps you already know from past experience that the humming (or buzzing) sound coming from your garbage disposal is usually an indication that your unit isn’t working as it should be.

Usually, this has something to do with jamming or the motor being clogged, which may come about for a variety of reasons, like small bits of food getting stuck inside or big chunks of food being thrown away after having been pulverized into mush over time by the blades.

Fortunately, there is always a solution at hand when dealing with these problems, and we’re more than happy to help.

In this article, we will discuss some common issues with garbage disposals that are humming but not working.

Jammed disposal

Disposal issues are a common trouble area for many homeowners.

To unclog and fix the issues associated with your disposal, you will want to make sure the wastewater has been drained.

If there is anything in the disposal, you can use tongs or pliers to remove it from the drainpipe, but don’t force it so stop if something gets stuck.

Simply try unplugging your disposal and then pushing it on manually and rotating the blades around manually for 10-15 seconds.

Make sure nothing is obstructing them, either at the top or bottom. If everything works fine after this point, your issue is resolved!

Defective Motor

If a disposer requires too much force to turn or it makes an odd noise when attempting to start it, this may indicate that the disposal itself is faulty.

If so, this means that you need to replace the disposer unit rather than attempt to repair it.

Be sure the source of your blockage and leak is removed before removing the faulty disposer; otherwise, any water remaining in the pipes could damage them and render them unusable.

Shredding Plate Failure

If your grinding plate is jammed, insert a broom handle through the top opening of the disposer and wiggle it in order to clear it. After loosening the plate, turn on the disposer again to be sure that the vibration has resumed.

If it still doesn’t work or if you don’t have access to the top of the disposer, insert an Allen wrench into the bottom of it and try clearing your jam from there.

If, after doing all this, there’s no change in your disposal’s ability to function, then you definitely need to replace your entire equipment!

Impeller Blades Might be Broken

A lot of issues that you will read about below have to do with homeowners putting things down their disposals that they really should not.

We’ll start with the harder materials first. Pits, bones, ice, and more are things homeowners shouldn’t put down their disposals.

These materials are far too tough for the impeller blades to properly chop into pieces small enough to fit down the disposal line.

What’s far more likely to happen is that these materials will break off the impeller blades, making your disposal pretty much useless for, well, disposing of things.

Throw these things away instead of putting them down at their disposal.

Clogged Drain Line

If you have ever seen your garbage disposal spewing hums but not working, then chances are you have a clogged drain line.

The drain line is the link between the garbage disposal and the sewer system. You should keep it free and clear to help prevent spillage in both your plumbing and your kitchen sink.

Most damaging to the drain line are fats, oils, and grease (FOG). It commonly gets dumped down as liquid after being used in cooking, but as it cools, it congeals and sticks to the walls of the drain pipe, causing restrictions.

To clean out the FOG build-up or even a plastic or paper bag stuck in the disposal, slide it from side to side until dislodged if nothing else works.
