Tripping of the circuit breaker occurs when the electric system is overloaded with many kitchen appliances running simultaneously. It then strains the voltage and leads to tripping of power supply from the main transmission switch for the whole kitchen.
The breaker has three settings, namely; on, neutral and off indicator. When you check and find out that it is off-switching, reset it back to on. You may consider turning off some of the apparatus that are not necessary to allow you maximum use of garbage disposal at that time.
4. Remove clogging materials
It is without a doubt that clogging can be a nuisance. It is caused by the lack of quick running water down the disposal or lack of water at all. The trap will get coated with food waste hence obstructing the free flow of the waste into the drain. After the disposal unit grinds the waste, it is supposed to find its way into the drain line.
Clogging may also be caused by some ground particles stick in the pipes, and the common type of waste is from starchy foods like potatoes and bananas. An easy way out of this problem is to avoid using it if there is no running water.

Typically, clogs occur at the sharp bends of the trap. Use a brush to scoop all the debris and check for any obstruction in the drain pipe. If the clogging is in the drainpipe, use a sink auger to clear it. In the end, fix the drain trap into the pipe and then run the water through to ensure the obstruction is cleared and your garbage disposal resumes function without humming.
5. Replacements to take care of Wear and Tear
It is worth to note that any item has its lifespan and may require replacement from time to time. Though garbage disposal may last long, they still need replacement with time.
