How to Fix / Troubleshooting
Safety First: Immediately stop using the disposal and turn OFF the breaker. Do not touch the sink or disposal until the issue is resolved.
Step-by-step:
- 1. Verify grounding: Inspect the disposal's electrical connection. Ensure the green ground wire from the KitchenAid disposal is securely connected to the house ground.
- 2. Check outlet ground: Use a receptacle tester to verify proper grounding at the outlet feeding the disposal.
- 3. Tighten ground connections: In the junction box and panel (by a qualified person), ensure all ground wires are tight and properly bonded.
- 4. Inspect cord: Replace any damaged power cord that may expose live conductors to the housing.
- 5. Test with meter: Confirm no voltage exists between the sink and a known ground before resuming use.
When to call a technician: Any shock or tingle issue should be evaluated by a licensed electrician to ensure safety.
