Having a garbage disposal in your home can make life a little easier. These can save a lot of time in the kitchen and provide better waste management in the community. However, when it stops working, it can be frustrating.  

When your garbage disposal won’t turn off, it can be dangerous to try and mess with it yourself. You need to consider some of the different options you can utilize to help turn it off and get it working as well as before again.  

When your garbage disposal won’t turn off, it will be dangerous to get anywhere near it. You need to take the time to fix the garbage disposal and get it to stop spinning around.

But first, you need to make sure that you know what is causing the issue in the first place. Some of the common reasons why my garbage disposal is not turning off include: 

1. Wiring Issues 

If the wiring is off in your garbage disposal, then the garbage disposal may not know when to turn off, even when you turn the switch. Wiring a garbage disposal is something you might be able to fix yourself, but if you're unsure, call an electrician. This will help make sure that no one gets hurt and that the garbage disposal will work again.  

2. Electrical Switch Problem 

The electrical switch could have some problems turning on and off at the time. You can try to move the plug-in to another outlet to see if that will help. If this helps, then there is a problem with the outlet. If the reset is not working, the electrical problem could be further in than what you can do on your own. 

3. Garbage Disposal Not Installed Correctly

If the garbage disposal was not installed the right way, then this could cause it to not turn off when you are done using it. Consider whether there seems to be several problems with the disposal and get it fixed that way. An electrician may need to come to look at the installation and see if they can change it around.  

4. Circuit Breaker or Fuse Problem 

When the circuit breaker is not working well, it may affect how well the garbage disposal will work. You should check the breaker and see if this is causing the problem. Turn the breaker to the garbage disposal on and off and see if that can stop the problem.

    Move the cord over to the next one on the outlet. This should be above or beside the original outlet.

You can still use the sink, even if the garbage disposal is not working. You can run water through it and wash the dishes just like normal. You just will not be able to run food through the disposal, but the rest of the sink will work fine.  

Why can’t I reset my garbage disposal? 

When a homeowner is not able to reset their garbage disposal, it is because there is an electrical problem.
