Tweeny Electrical Contact Arcing / Low Voltage to Motor

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

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn wall switch contacts, Loose wire nut connections, Undersized wiring, Shared overloaded circuit

Safety First: Turn OFF the breaker before working on electrical components.

Step 1 – Replace wall switch: Install a new, properly rated switch for motor loads.
Step 2 – Tighten connections: Check all wire nuts and terminal screws in the switch box and disposal junction box.
Step 3 – Avoid shared heavy loads: Do not run high-draw appliances on the same circuit while using the disposal.

If buzzing persists after electrical repairs, the motor may be failing and the unit should be replaced.
