An Expert Guide to Garbage Disposal Parts

Garbage Disposal is a critical part of your kitchen, it is important to know its key components and how they work together.


At the core of your garbage disposal, commanding the operation is the motor. This mighty little engine powers the grinding action, slicing and dicing your leftovers into tiny bits. It’s typically rated by horsepower, with 1/3 to 1 horsepower models being most common in household use. 

Grinding Chamber

Bound to the motor is the grinding chamber, often made from durable materials like stainless steel or galvanized steel. This is your system’s brawn, where the food waste is ground up. 


There’s the impeller, or grinding wheel, and the shredder ring which shows food scraps.

Reset button and switch

Now, controlling all this power is the reset button and the switch. The reset button, usually red and located on the bottom of the unit, restarts the motor if it’s overloaded. The switch, on the other hand, is located in your kitchen at an easily accessible place, providing you with the ultimate on-off power. 

Dishwasher Drain Connector

The last key player is the dishwasher drain connector. If you have a built-in dishwasher, this piece directs the water and food particles from the dishwasher into the disposer, ensuring no morsel escapes its deserved fate. 

What materials are typically used in Garbage Disposal parts?

Galvanized or stainless steel

The vital components such as grinding chambers and impellers are made from galvanized steel, stainless steel, or a combination of both.  Because these materials are rust and corrosion-resistant that ensures the life span of your unit.  Beware of the galvanized steel variant, it may be budget-friendly.

High-strength plastics

On another note, you may come across some components made from high-strength plastics. Yes, you heard that right – plastic in a garbage disposal. While it might sound strange, these plastics are incredibly reliable. They are commonly used for the inner linings and protective casings, offering exceptional resilience against daily wear and tear. 

Copper wirings

All the while, don’t forget about the electrical components. These parts are usually insulated copper wiring, kept safely away from the wet waste. Copper, in this case, is the go-to material due to its excellent conductivity properties.

Common Issues with Garbage Disposal Parts and How to cope with them?

Garbage disposals are quite convenient for handling domestic and restaurant waste. But they can sometimes encounter problems. These issues mostly occur due to breakdown or dysfunction within the key components of your garbage disposal system. Knowledge of these parts can make it easier for you to troubleshoot problems when needed. 

Malfunctioning flywheel

The first part to mind should be the flywheel. The flywheel is the component that gets things chopping. A malfunctioning flywheel can leave you with an inefficient or even non-functioning garbage disposal system. One telltale sign of a bad flywheel is if the disposal unit hums but doesn’t grind. If this happens, a simple reset of your garbage disposal could do the trick. 

Clogging in Impellers

Now, look at the impellers. These are attached to the flywheel, and they help to force the waste materials down the drain after the wastes are ground up. Impellers that are not working well may not fully dispose of the waste which leads to blockages. Unclogging may be necessary to cope with this issue,

Damaged shredder ring

The shredder ring cuts and shreds the waste into manageable bits that the impellers can easily force down the drain. If it gets dull or damaged, the shredder ring will not function at its optimum. Replacing it may be necessary to cope with this issue.

A burnt-out motor

The “heart” of the disposal is the electric motor, without which your garbage disposal unit would not work at all. It starts with the flywheel, shredder ring, and impellers. It creates the necessary mechanical energy to get rid of your waste. If you’re experiencing issues with your disposal unit’s motor, such as a burnt-out motor. You might need to consider a complete garbage disposal replacement. 

What are some safety precautions to take when handling Garbage Disposal parts?

If working with an already installed unit, the paramount rule is, never to stick your hand or any other object into the garbage disposal. 

Use of Pliers

In case of any blockages or jams, always use pliers or a similar tool for extraction. Importantly, before starting any kind of work with your garbage disposal unit, ensure it is completely disconnected from the main power source to prevent any accidental activation.
