Read the directions for your model before attempting a home repair. Most disposals have an electrical reset button, and a manual hex key for un-jamming. If the disposal stops working, its internal circuit breaker may have shut it off. Turn the switch definitely off, and try to pull out the hard object that may have jammed it. Then use the right-sized hex key to manually turn the rotor parts (usually directly under the unit in the center). If it turns, then push the reset button. It usually clicks in. Then, turn on the water and try the power, again.
No need to worry if your garbage disposal is on the fritz—installing a new one is a straightforward project that you can do yourself in just a few minutes. Start by switching off the power to the disposal at your home’s breaker box to ensure that you can work safely. Next, remove the old unit by detaching it from the mounting ring directly beneath the sink drain. Finally, install any necessary new mounting hardware, fit the new disposal into place, and turn on the water to test for leaks before giving it a trial run.

Lay the disposal on its side under the sink so you can make the electrical connections. Make sure the circuit breaker is off. Remove the plate on the bottom of the disposal to expose the wiring and use wire connectors to connect the wires from the disposal to the matching wires from the power supply. Finally, secure the power cord to the bottom of the disposal using the proper connection. Replace the plate to cover the wires. (See Fig 6)

Most garbage disposals are sealed using plumber’s putty. You’ll need to detach the garbage disposal, clean off the old putty and reseal. Other types of disposals use only a flange that is tightened and compressed with screws. This may need to be replaced. Either way, this can be a big job if you don’t know what you’re doing (requires removing and replacing drain pipes, as well).

Lowe's offers garbage disposals like the InSinkErator Evolution and Badger garbage disposals in various horsepower options. Models with lower horsepower tend to become jammed easily. What if your garbage disposal jams? No problem. Simply locate the hex socket in the center of the underside of the disposal. Grab a hex wrench, put it in the socket, and work it back and forth until you feel the blades loosen up. Once the blades are spinning freely, press the garbage disposal reset button. It's that easy.

Replacing a failed garbage disposer can seem daunting. There's the usual trepidation about electricity and water, the unfamiliar sink connection and enough drain fittings to make leaks a real possibility. Then there are the hassles of comparison shopping and the suspicion that the job could run into real money. And finally, failed disposers don't often leak, at least not in the beginning, so it's easy to put things off.

The horror movie image of victims having hands and arms severed in a garbage disposal is entirely a Hollywood invention. In reality, the blades inside a garbage disposal are rather dull grinders, not gleaming, razor-sharp sabers. That is not to say that a disposal should be taken lightly—it is indeed possible to be painfully injured if you don't practice basic safety measures. 
Some folks knocked the instructions. Take heart. It appears that the Waste King guys have heard the criticisms from the negative reviewers. I am guessing that they have been re-written to better explain the installation because they are really easy to follow. My best advice is this: don't be afraid of a difficult or confounding set of installation instructions. It is really easy. Here's what you do. Go to and search for a video on How To Remove Your Existing Garbage Disposal because this is the hardest part. You will find one that matches yours. Watch it. I started removing the Badger incorrectly, stopped, watched a video, and then it was a piece of cake. In my case, I shouldn't have removed the three long screws before removing the body of the old one. You do it after it is disconnected. READ the instruction manual carefully. Then go ahead and youtube the Waste King installation video. It is very easy once you see it done. No filing or grinding gaskets, and Good Lord, no car jacks under your sink please. If it is hard then you are doing something wrong. STOP!!! Review the procedure. Start again. The directions are actually very explicit. The parts are well labeled. The diagrams show you what to do. The videos show you what to do. If you prepare yourself (15 minutes of reading and watching videos, tops) you will fly though the installation and be a happy person.
