Possible Causes
Underrated wall switch for motor load, Loose switch terminal screws, Failing switch contacts, High inrush current from aging motor
How to Fix / Troubleshooting
Safety first: Turn off the breaker before removing the switch cover.
- Tighten terminals: Check that all wires on the wall switch are firmly secured under the screws.
- Replace switch: Install a new switch rated for motor loads (typically 15A or 20A) as recommended for Whirlpool disposals.
- Monitor operation: If buzzing persists with a new switch, the motor may be drawing excessive current and the disposal may need replacement.
