How to Fix / Troubleshooting
Safety first: Turn OFF the breaker before inspecting wiring or outlets.
- Step 1 – Check plug and cord: For corded units, ensure the plug fits snugly in the outlet and the cord is not damaged or pulled tight.
- Step 2 – Inspect junction box: Remove the disposal's junction box cover and tighten all wire nuts. Re-strip and reconnect any loose wires.
- Step 3 – Test wall switch: Wiggle the switch gently (with cover on) while the disposal is running. If it cuts in and out, replace the switch.
- Step 4 – Secure cables: Use cable clamps or staples (per code) to prevent movement of the cable that could loosen connections over time.
Warning: Intermittent electrical connections can overheat and pose a fire risk.
