Garbage disposals are essential appliances in modern homes. They make cleaning up after meals easier by grinding up food waste, but they can also cause problems. When a garbage disposal isn’t working correctly, it can be frustrating and lead to unsanitary conditions. In this article, we’ll go over some common problems that can occur with garbage disposals and how to troubleshoot them, and how to tell when it’s time to get hire a garbage disposal repair professional.
The Garbage Disposal Won’t Turn On
If you’re dealing with a garbage disposal that won’t turn on, it can be frustrating and even overwhelming. Fortunately, there are a few troubleshooting steps you can take before you need to call a professional. Here’s a quick guide you can follow to help identify the problem, with detailed steps to get your garbage disposal up and running again.
- Check the Power Supply
The first thing to check is whether the garbage disposal is receiving power. Start by checking the outlet and the switch that controls the garbage disposal. Check the circuit breaker or fuse box, and see if the circuit that powers the garbage disposal has tripped or blown. If the power supply is the problem, reset the circuit breaker or replace the blown fuse, and see if the garbage disposal turns on.
- Reset the Garbage Disposal
If the power supply isn’t the issue, the next step is to reset the garbage disposal. Look for the reset button on the bottom of the garbage disposal unit, and press it. This will reset the internal circuitry of the unit and may solve the problem. Once the reset button is pressed, try turning on the garbage disposal again.
- Remove Blockages
Another common cause of garbage disposal not turning on is a blockage in the unit. Over time, food particles and other debris can build up and cause the blades to become jammed. If this is the case, you will need to remove the blockage before the garbage disposal can function again.
To do this, turn off the power supply to the unit, and look for any visible debris in the garbage disposal. Use tongs or pliers to remove the blockage, taking care not to damage the blades. Once the blockage is removed, turn the power supply back on, and try turning on the garbage disposal again.
- Check the Wiring
If the garbage disposal still won’t turn on, the next step is to check the wiring. Turn off the power supply to the unit, and remove the unit from under the sink. Check the wiring connections to make sure they are secure and free of any damage. If there is any damage, you may need to replace the wiring.
- Replace the Garbage Disposal Unit
If none of the above steps work, the final solution may be to replace the garbage disposal unit altogether. If the unit is old or has been in use for a long time, it may simply be time for a replacement.

The Garbage Disposal Is Jammed
A jammed garbage disposal is another common problem that homeowners encounter. If you hear a humming sound but the disposal isn’t grinding, it’s likely that something is jamming the blades. Garbage disposals are designed to shred and grind food waste so that it can be easily flushed down the drain. Most garbage disposals consist of a motor, a grinding chamber, and a hopper. When you turn on the disposal, the motor rotates the grinding chamber, which grinds up the food waste. The ground-up food waste is then pushed through the hopper and down the drain.
Reasons Why Garbage Disposals Become Jammed
There are several reasons why garbage disposals can become jammed. Some of the most common reasons include:
- Overloading the garbage disposal: Garbage disposals are designed to handle a certain amount of food waste at once. If you try to cram too much food waste into the disposal at once, it can become overwhelmed and jammed.
- Putting the wrong types of food waste in the disposal: Not all types of food waste are suitable for grinding in a garbage disposal. For example, fibrous vegetables like celery and artichokes can wrap around the blades and cause the disposal to become jammed.
- Using dull blades: Over time, the blades in your garbage disposal can become dull. Dull blades are less effective at grinding up food waste, which can cause the disposal to become jammed.
- Foreign objects in the disposal: Sometimes, non-food items can accidentally fall into the garbage disposal, causing it to become jammed. This can include things like utensils, bottle caps, and small pieces of plastic.
Troubleshooting Tips for a Jammed Garbage Disposal
If your garbage disposal becomes jammed, there are several troubleshooting tips that you can try before calling a plumber. Here are some of the most effective solutions:
- Turn off the power: Before attempting to fix your garbage disposal, make sure that the power is turned off. You can do this by unplugging the disposal or turning off the circuit breaker that controls it.
- Check for foreign objects: Use a flashlight to check the inside of the disposal for any foreign objects. If you see something, use a pair of tongs or pliers to remove it. Never put your hand inside the disposal.
- Clear out any food waste: Use a long-handled brush or a wooden spoon to clear out any food waste that is stuck in the disposal.
- Reset the disposal: Many garbage disposals have a reset button on the bottom. Pressing this button can sometimes fix the problem.
- Use an Allen wrench: If your disposal has an Allen wrench socket on the bottom, you can use an Allen wrench to manually turn the blades and clear any obstructions.
- Call a plumber: If you have tried all of the above solutions and your garbage disposal is still jammed, it may be time to call a plumber. A professional plumber will have the tools and expertise necessary to fix the problem

The Garbage Disposal Is Leaking
Leaks in a garbage disposal can be caused by a variety of issues, such as a damaged gasket or loose connections. A leaking garbage disposal can be a major headache for homeowners. Not only can it cause a mess, but it can also lead to further damage to your kitchen appliances, floors, and cabinets. If you’re experiencing a leaking garbage disposal, it’s important to act quickly to avoid additional problems.
Here are some troubleshooting tips to help you identify the cause of your leaking garbage disposal and the steps you can take to fix it:
- Check the Sink Flange
The sink flange is the metal ring that sits at the top of the garbage disposal unit. If the sink flange is not sealed properly, water can leak through the seal and into the cabinet below. To check the sink flange, turn off the power supply to the garbage disposal and remove the sink flange. Inspect the seal and tighten the screws if necessary.
- Check the Dishwasher Connection
A common cause of a leaking garbage disposal is a faulty dishwasher connection. If the dishwasher hose is not connected properly, it can cause water to leak out of the garbage disposal unit. To check the dishwasher connection, turn off the power supply to the garbage disposal and inspect the connection. If the connection is loose, tighten the clamp or replace the hose if it’s damaged.
- Check the Drain Lines
The drain lines can become clogged, causing water to back up and leak out of the garbage disposal. To check the drain lines, turn off the power supply to the garbage disposal and disconnect the drain pipes. Inspect the drain lines for any blockages and remove any debris or buildup.
- Check the Garbage Disposal Unit
A damaged or faulty garbage disposal unit can also cause water to leak out. To check the garbage disposal unit, turn off the power supply and inspect the unit for any cracks or damage. If the unit is damaged, it will need to be replaced.
- Check the Mounting Assembly
The mounting assembly connects the garbage disposal unit to the sink. If the mounting assembly is loose or damaged, water can leak out. To check the mounting assembly, turn off the power supply to the garbage disposal and inspect the assembly. If it’s loose, tighten the screws. If it’s damaged, replace the assembly.

The Garbage DisposaI Is Making Strange Noises
If your garbage disposal is making strange noises, such as grinding or rattling, it’s likely that something is stuck in the blades. There are several other reasons why your garbage disposal may be making strange noises. The most common causes of strange noises are clogs, damaged blades, or a faulty motor. Some other less common causes could be loose screws, worn-out bearings, or even foreign objects in the garbage disposal.
What Causes Garbage Disposal Units To Make Strange Noises
Clogs
One of the most common causes of strange noises coming from a garbage disposal is a clog. A clog can occur when food particles or other debris become stuck in the disposal. This can cause the motor to strain, resulting in a grinding noise. To fix a clog, turn off the garbage disposal, and then try using a plunger or a drain snake to remove the clog. You can also try pouring hot water down the drain to help break up the clog.
Damaged Blades
Another common cause of strange noises from garbage disposal is damaged blades. Over time, the blades in a garbage disposal can become dull or even break, causing a rattling or grinding noise. If this is the case, you will need to replace the blades. To do this, turn off the power to the garbage disposal, remove the old blades, and install new ones.
Faulty Motor
A faulty motor can also cause strange noises to come from a garbage disposal. If the motor is damaged or worn out, it may make a humming or grinding noise when it is turned on. In some cases, the motor may even stop working altogether. If this is the case, you will need to replace the motor.
Loose Screws or Worn-Out Bearings
Loose screws or worn-out bearings can also cause strange noises from a garbage disposal. If the screws that hold the disposal in place become loose, the disposal may vibrate, resulting in a rattling noise. Similarly, worn-out bearings can also cause a grinding noise. To fix this issue, you will need to tighten the screws or replace the bearings.
Foreign Objects
Foreign objects, such as silverware, can also cause strange noises from a garbage disposal. If you suspect that there is a foreign object within your garbage disposal, turn off the power and use a pair of tongs or pliers to remove it. Avoid using your hands, as the blades in the disposal can cause serious injury.
How To Troubleshoot A Garbage Disposal Unit Making Strange Noises
If your garbage disposal is making strange noises, there are a few steps you can take to troubleshoot the issue. First, turn off the power to the disposal to avoid any accidents. Next, check for any clogs, damaged blades, loose screws, worn-out bearings, or foreign objects. Once you have identified the problem, follow the appropriate steps to fix it.
If you are unsure of how to fix the problem, it may be best to call a professional plumber. They will be able to diagnose the issue and provide the appropriate solution. Attempting to fix garbage disposal without the proper knowledge or tools can be dangerous and lead to more extensive damage.

The Garbage Disposal Smells Bad
Smelly garbage disposal is a common problem that is easily fixed. The smell is usually caused by food waste that has become trapped in the disposal. Dealing with a bad smell from your garbage disposal can be an unpleasant experience. It’s not only embarrassing but can also be a sign of a more serious problem with your disposal unit.
What Causes Garbage Disposal Smells?
The most common cause of bad smells coming from garbage disposal is food waste that gets stuck in the unit. When food is left in the disposal for an extended period, it can rot and cause a foul odor. Some other causes of garbage disposal smell include:
- Bacteria and mold: When food waste is left in the disposal, it can attract bacteria and mold that thrive in warm, damp environments. These microorganisms can produce a foul smell.
- Clogged pipes: If the pipes that lead from the disposal are clogged, water and waste can back up into the unit, causing a bad smell.
- Old and worn-out parts: Over time, the blades, gaskets, and other parts in the garbage disposal can wear out, creating a bad smell.
How to Troubleshoot Garbage Disposal Smells
Now that we’ve identified some of the causes of garbage disposal smells let’s look at some steps you can take to troubleshoot and get rid of the odor.
Step 1: Run Cold Water and the Disposal
The first thing you should do when you notice a bad smell coming from your garbage disposal is to run cold water and turn on the disposal. The water will help to flush out any food particles or debris that might be stuck in the unit.
Step 2: Use Ice and Salt
To help remove any food waste that may be stuck in the disposal, you can try running ice cubes and salt through the unit. The ice will help to break up any debris, while the salt will act as an abrasive to help scrub away any stubborn particles.
Step 3: Clean the Disposal
Cleaning the garbage disposal regularly can help prevent bad smells from developing. You can clean the unit by pouring a mixture of baking soda and vinegar down the drain. Let the mixture sit for a few minutes before running cold water and the disposal.
Step 4: Use Citrus Fruits
Another effective way to get rid of bad smells from your garbage disposal is by using citrus fruits. You can cut up a lemon, lime, or orange and put the slices down the disposal. The citrus oils will help to freshen up the unit and eliminate any odor.
Step 5: Call a Professional
If you’ve tried all the above steps and still have a bad smell coming from your garbage disposal, it’s time to call in a garbage disposal repair professional. A plumber can inspect your unit to identify any underlying problems and fix them.
