To get a better idea of how to fix a garbage disposal, you need to find out how a garbage disposal works. When you turn on the disposal, a spinning disc spins quickly, pulling food into the grinding chamber.

This grinds the food up and allows it to be small enough to pass through the pipes with water from the sink. Garbage disposals are powerful, though, despite popular belief, they do not have sharp blades. 

They grind the food with discs that aren’t sharp enough to cut someone but nevertheless, can be dangerous. Primarily because of the force used paired with the fact that most garbage disposals plug into an outlet. 

Garbage Disposal Parts

Each garbage disposal is a little different than other garbage disposals. Some have dishwasher attachments, while others are fairly basic. But these are common parts that come together to make this food-grinding machine. 

  • Stopper – the plug of the disposal. 
  • Flanges – to strengthen the position of the hopper.
  • Hopper – the chamber where food is ground. 
  • Stopper Switch – controls the stopper. 
  • Shredder Ring – contains the impeller and helps to grind food.
  • Impeller – pulls food down to be ground up. 
  • Drain Opening – houses water and food to be drained.
  • Shredding Housing – holds the drain chamber and is the lower part of the hopper.
  • Sink Drain – the drain that allows food to pass through to pipes. 
  • Power Supply – this will usually be a wall switch into the outlet to power the garbage disposal. 
  • Reset Button – resets the garbage disposal as the first reaction to troubleshooting problems.

If the above tips didn’t help you fix your garbage disposal, then you may find the following tips useful.

Here are some common problems and how you can fix them.

Not Responding

This means the garbage disposal isn’t getting any power to the unit. If you suspect this is the problem, check your home’s electrical panel. If you hit the reset switch, make sure the outlet has power. Unplug the garbage disposal and plug in something else.

Garbage Disposal Humming

When you hear a humming sound, it means your garbage disposal is jammed. Unclog the device with a hex wrench. Before you do anything, unplug the disposal. If you can’t get through the disposal, you may need to use small tongs to clear the drain.

Draining

This can mean that the garbage disposal drain has a problem. If this is true, it’s more of a plumbing problem than a disposal problem. You need to take the disposal out to fix this problem.

After you take it out, you can fix the pipe that isn’t draining and put the garbage disposal back in without a problem.

Leaking

When there’s a leak, look for water dripping from the pipes or base. Finally, look at the bottom of the garbage disposal.

If you’ve determined that you have a leaking problem before you can fix it, tighten any loose areas. If there is a loose area but you can’t tighten it, there could be a broken screw. Take it off and find out which piece needs to be replaced. 

Grinding

If your disposal isn’t grinding well, try running extra water through the thing. Many people don’t use enough water when grinding their food. Never be afraid of using too much as this won’t cause problems. 

Tips To Prevent Garbage Disposal Problems

Just like anything else in your kitchen, you want to take care of your disposal. Here, we’ll provide you with a few tips that will keep your disposal healthy.

Tips To Prevent Garbage Disposal Problems

Run Cold Water During Usage

Don’t Overstuff

Do not put too much food in your disposal as large food items can get stuck in it. You don’t want to hire the services of a professional plumber for something as minor as a large piece of chicken, for example.

If you have a lot of food to process, do it slowly. Simply pushing food down your disposal drain with a long stick would not be a good idea. You should only grind food up into little pieces. You can also use a sink auger to clear your drain line and sink drain opening.

No Chemicals

Chemicals can harm your disposal. They won’t jam it up but corrosive chemicals could harm the discharge pipe or discharge tube. Never pour bleach or drain cleaner down the same drain trap as your disposal.
