Garbage disposal switch produces a buzzing sound but the unit does not start.

Safety first: Turn off the breaker before removing the switch cover or touching any wiring.

• Inspect the switch: Remove the wall plate and gently pull out the switch. Look for discoloration, melted plastic, or loose wires.
• Tighten connections: Ensure all wires are firmly secured under the terminal screws. Re-terminate any back-stabbed connections to screw terminals.
• Replace the switch: Install a new heavy-duty switch rated for motor loads (typically 15A or 20A) if there is any sign of damage or buzzing persists.
• Test operation: Restore power and test the disposal. If it still does not start, the issue may be with the disposal itself.

A buzzing switch is a fire risk; replacing it with a properly rated unit is essential for safe Maxmatic disposal operation.
