Whirlpool garbage disposal emits a burning smell or smoke when running.

Safety first: Immediately turn off the disposal and switch off the breaker. Do not continue to run a smoking or burning-smell unit.

• Allow cooling: Let the unit cool completely for at least 30 minutes.
• Check for jams: After cooling and with power off, use a wrench in the bottom hex socket to ensure the impeller spins freely. Remove any obstructions from the chamber with pliers.
• Inspect for visible damage: Look for burn marks on the housing or wiring compartment.
• Test briefly: Restore power and run the disposal for only a few seconds with water. If the burning smell returns or the unit hums and trips, the motor is likely damaged and the disposal should be replaced.
