The answer to 'what causes garbage disposal' is that a garbage disposal can malfunction or stop working for several reasons, including jams, clogs, motor failure, or electrical issues. Overloading the disposal with too much food waste, trying to grind up hard items like bones or shells, or not using the disposal properly can all lead to problems.
Garbage disposals are convenient kitchen appliances, but they do require regular maintenance and care to keep them running smoothly. Proper usage, regular cleaning, and prompt attention to any issues can help extend the life of your disposal and prevent costly repairs.
