How to Fix / Troubleshooting
Safety warning: Turn off the breaker before removing any switch plates or junction box covers.
- Step 1 – Test outlet (corded models): Plug in a lamp to confirm the outlet is live when the switch is ON. If not, suspect the switch or wiring.
- Step 2 – Inspect switch: Remove the wall plate and gently pull out the switch. Tighten any loose terminal screws and replace the switch if it appears burned or worn.
- Step 3 – Check junction box: Under the sink, open the disposal junction box and verify all wire nuts are tight and wires are intact.
- Step 4 – Restore power and test: After reassembling, turn the breaker back on and test the disposal.
- Step 5 – If still dead with confirmed power: The issue may be internal to the disposal; replacement is likely required.
