F.32 — Fan fault

What does F.32 mean?

• Plug at the fan is not correctly plugged in or has come loose.
• Multiple plug on the PCB is not correctly plugged in.
• Break or damage in the cable harness connected to the fan.
• Fan is mechanically blocked or the Hall sensor (speed sensor) is defective.
