Possible Causes

Overloaded McAlpine motor from frequent heavy use, Failing motor windings, Seized upper or lower motor bearing, Blocked ventilation around motor housing

How to Fix / Troubleshooting

Safety first: Turn off power immediately if you smell burning. Do not continue to run the unit.

  • Allow cooling: Leave the unit powered off for at least 30–60 minutes to cool and reset the internal thermal protector.
  • Check for jams: Use the hex key at the base to ensure the rotor turns freely. Clear any obstructions from the grinding chamber with pliers.
  • Inspect ventilation: Ensure the area around the McAlpine motor housing is not blocked by stored items and that air can circulate.
  • Test lightly: Restore power and run the unit with water for a few seconds only. If the burning smell returns quickly or the unit stops again, discontinue use.

Repeated overheating or burning odour indicates serious motor damage. The safe remedy is replacement of the motor assembly or the complete McAlpine disposal.
