The answer to 'garbage disposal not working' is the garbage disposal is not functioning properly and needs to be repaired or replaced. Common causes include a jammed or clogged disposal, a broken motor, or a tripped circuit breaker. Symptoms may include the disposal not turning on, making strange noises, or not grinding food properly.
For minor issues, you may be able to troubleshoot and fix the disposal yourself. Try resetting the disposal by pressing the reset button, removing a jam, or checking the circuit breaker. However, for more complex problems like a broken motor or leaks, it's best to call a professional plumber to properly diagnose and repair the disposal.
