If you spend a lot of time in the kitchen, your garbage disposal is an essential convenience. That's why it's so disheartening when you flip the on switch only to be confronted by silence or a strange humming sound. If your garbage disposal isn't working right, it's probably due to one of the following problems:
Jammed Disposal
Perhaps the most common issue, garbage disposals become jammed when an object gets locked in the impeller blades. The object could be a bit of food detritus—like a bone—or it could be an item that accidentally fell down the disposal—like a fork or knife. If your disposal is jammed, it will make a humming sound when you try to turn it on. The power turns on, but the blades are unable to rotate.
Poor Drainage
If your garbage disposal isn't draining properly, there's probably something obstructing the disposal's pathways. The obstruction may be located in the drain trap, an s-shaped plumbing line through which discharge travels. The obstruction could also be located in the line that connects with the wall. If the obstruction is here, you may have to use a plunger to force it out. Consider hiring a professional plumber to get rid of this sort of clog.
Disposal Won't Turn On
If nothing happens when you try to turn on your garbage disposal, several issues could be at work. First, the plug might have pulled out of its socket. Check to see whether it's still secure before considering any other options. You can also try resetting the garbage disposal; most units come with a reset button. You can also try resetting the circuit breaker. If none of the easy options solve the problem, it may be time to call in a professional plumber. Your garbage disposal's switch may be broken, and replacing it requires electrical know-how.
If your garbage disposal isn't working, you may be able to fix it with an easy, DIY solution. When the job gets tricky, however, a simple "plumber near me" search will help you find a professional to tackle the job.
