Possible Causes

Defective evaporator fan motor, Faulty fan speed control circuit on PCB, Wiring harness damage, Obstruction in fan housing

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the fan assembly.

  • Inspect fan area: Remove the internal rear panel and check for ice or debris obstructing the fan blades.
  • Test fan motor: With a multimeter, check for appropriate resistance across the fan motor terminals. An open circuit indicates a failed motor.
  • Replace fan: If the motor is faulty or noisy, install an Ariston-compatible evaporator fan motor.

When to call a technician: If a new fan does not resolve F5, the fan control circuit on the main PCB may be defective.
