Tweeny High Start-Up Current / Marginal Circuit Capacity

Garbage disposal causes lights to dim significantly when starting

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

Shared circuit with lighting, Long wire run with voltage drop, Aging motor drawing excess current, Undersized breaker or wiring

Safety First: Consult electrical codes before modifying circuits.

Step 1 – Check circuit loading: Identify all devices on the same circuit as the Tweeny disposal. Avoid running multiple high-load devices simultaneously.
Step 2 – Inspect for jams: Ensure the rotor spins freely; a jam increases start current.
Step 3 – Consider dedicated circuit: For persistent dimming, have an electrician install a dedicated circuit for the disposal.
