Proven! Best Step by Step To Fix Humming Garbage Disposal


Have you ever been victimized by a humming garbage disposal and just can’t understand why it is happening? Well, don’t feel too bad because it does happen every so often. So let’s try to understand more about it.

Reason why humming garbage disposal is exist.

Before you go to the humming garbage disposal, there are few things you need to know about the garbage disposal concept itself. When you know the function and how it works, you will understand easily why it’s humming.

There are several reasons why a humming sound may come from your garbage disposal. Here are some of the possibilities:

  • An object is stuck and has jammed the motor. That is where the humming sound is coming from. This means once it is dislodged, the humming sound should go away.
  • Overheating is another reason why you may hear such a sound. Allow it to rest for a bit before pushing the reset button.
  • Another possibility is an electric overload that has tripped the breaker. Simply reset it to see if the humming sound has gone away.
  • Clogging is another reason, and similar to having a lodged object, it too will cause the motor to stop and possibly overheat. You need to clear the unit before operating it again.
  • The last possibility and probably the least you would want to happen is that it is time for you to replace your garbage disposal. This would mean additional cost on your part, but it will save you a lot of trouble.

Humming Garbage Disposal

How to repair humming garbage disposal?

It is not recommended, but if you would like to try your hand in repairing the humming sound coming from your garbage disposal instead of calling a licensed plumbing professional, then here are some suggested steps to follow:

  1. Turn off the garbage disposal and disconnect any electrical connection for your own safety.
  2. Use a flashlight to look down the drain and check for any obstruction.
  3. If there is something lodged down the drain, use a kitchen tong to pull it out.
  4. If there is nothing blocking the blades or hampering the motor, check if there is enough power to the unit. This is done by pushing the reset button of the unit. At the same time, make sure that you are using a GFCI outlet.
  5. Look for the breaker socket usually found at the bottom of the unit. Use an Allen Key and twist it back and forth to see if the blades are rotating freely.
  6. Turn the power back on and run water down the unit to flush any remaining waste down the drain. Use ice cubes to clean and sharpen the blades.

If there is still a humming sound coming from your garbage disposal unit, you may need to remove it to see if there is any waste that has built up. You have to manually scrape and flush this out. Reinstall the unit once cleaned.

Now, at this point you have two options. One is to buy a replacement unit or to call a licensed plumbing professional to properly trace and solve the problem.

How to prevent humming garbage disposal?

As we have discussed, one of the most common reasons for the humming is a blockage in the unit. To prevent this from happening, here are some of the things you shouldn’t throw inside garbage disposal.

  • Banana peels because these are too hard to grind;
  • Potato peels become starchy and gluey resulting in jamming;
  • All types of grease, which can slow down the turning of the blades and overwork the motor;
  • Pasta and rice because once these sit in water they expand and may prevent the blades from rotating freely;
  • Any kinds of bones because it will dull the blades, making grinding difficult;
  • Coffee grounds that can create blockage;
  • Egg shells also dull the blades and may cause the motor from working properly; and
  • Celery because just like banana, it is too tough to grind.

If you keep all of these away from your garbage disposal, then you shouldn’t be bothered by humming garbage disposal sounds for a considerably long time.
