Whirlpool garbage disposal starts by itself or turns on unexpectedly.

Safety first: Immediately turn off the breaker supplying the disposal. Do not leave a self-starting disposal energized.

• Inspect switch: Replace a suspect wall switch or air switch that may be intermittently closing.
• Check control module: For electronic models, inspect the Whirlpool control box for a stuck relay. Replace the module if necessary.
• Verify wiring: Have a qualified person check that the disposal is not incorrectly tied into another circuit or device.
• Keep power off until resolved: Do not restore power until the cause of unintended operation is corrected.
