Disposal will not turn on, no sound, but the wall outlet has power and the breaker is not tripped.

Safety first: Turn off the wall switch and isolate power at the breaker.

• Press the reset button: Locate the reset button on the underside of the McAlpine disposal and press firmly until it clicks.
• Allow cooling time: If the unit was recently overloaded, wait 10–15 minutes before attempting to restart.
• Check internal terminals: With power off, remove the lower cover and tighten the live and neutral terminal screws.
• Test operation: Restore power and briefly switch the unit on. If it still does not respond, the internal protector or motor may have failed.
