Replacing Your Garbage Disposal

By Bluehammer Admin

Your garbage disposal eats a lot of food and then one day it stops! The following are some helpful tips when it comes time to replace your Garbage Disposal.

It's broken.. or is it?

There are a few things you can do before you start heading to the local home improvement store or looking up plumbers. Important! Never put your hand down a garbage disposal while it's running!

  • Could it be jammed?Sometimes a hard piece that doesn't grind can fall into the drain and jam the unit making it seem like it is dead. Turn off your power, unplug your unit and remove the rubber part in the drain. Shine a light and make sure there is nothing stuck, if there is use pliers to fish it out.
  • Did you try the reset button?Garbage disposals work hard, sometimes too hard triggering their safety breaker. If you have been using your disposal before it shut off, wait ten minutes for it to cool down, and then press the reset button usually located on the bottom of the appliance.
  • Try and manually move the motorUnder the garbage disposal is a place for you to insert a hex wrench and manually move the motor. Doing this can loosen any jam and could get it working. Make sure your unit is off when you do this. After manually turning the motor back and forth try to turn on the garbage disposal.

Horsepower Options, Which One?

The most common household horsepower (hp) options for garbage disposals are 1/3hp, 1/2hp, 3/4hp and 1hp. For limited household use (1 -2 people) and grinding of soft foods a 1/3hp or 1/2hp unit will work although they will jam easier than the more powerful appliances. If you cook more and have a larger family it is suggested to lean more towards the larger 1hp appliances.
