Possible Causes

Normal cooling overrun behavior, Stuck fan relay on control board, Faulty temperature sensor reporting high temperature, Control board logic fault

How to Fix / Troubleshooting

First determine if behavior is normal:

  • Many Candy microwaves keep the fan running for a short period after cooking to cool internal components. This can last several minutes.

If fan runs excessively (e.g., 20+ minutes):

  • Unplug the microwave to stop the fan.
  • After cooling, plug back in and run a short cycle; observe if the fan again runs excessively.

Internal checks (experienced users):

  • Remove the outer cover.
  • Inspect the control board fan relay for signs of sticking or overheating.
  • Check the temperature sensor wiring for shorts that could falsely indicate high temperature.

Repair: A stuck relay or faulty sensor typically requires control board or sensor replacement by a technician.
