Disposal will not turn on at all; no sound, no hum, reset button not popped.

Safety first: Before touching wiring, turn OFF the breaker feeding the disposal.

• Check breaker: Locate the kitchen/disposal breaker in your panel. If it is in the middle or OFF position, switch it fully OFF then back ON.
• Check GFCI: If the disposal plugs into a GFCI outlet (often under the sink or on the backsplash), press RESET and test with a lamp.
• Test wall switch: Use a non-contact voltage tester at the switch. If no power is present on either terminal with the breaker ON, the feed is open; if power is present on line but not load when ON, replace the switch.
• Inspect junction box: With breaker OFF, remove the small cover where the cord or house wires enter the American Standard disposal. Tighten any loose wire nuts and ensure the ground wire is secure.
• Try reset button: Turn power back on and press the red reset button on the bottom of the unit.
