Possible Causes
Incorrect fan feedback signal, Failing fan motor, Loose fan blade on shaft, Control board fan driver fault
How to Fix / Troubleshooting
Safety first: Isolate power before accessing internal components.
- Visual inspection: Access the cooling fan and check that the blade is firmly attached to the motor shaft and not slipping.
- Check for obstructions: Ensure no insulation or wiring is interfering with the fan blades, which can alter speed.
- Connector check: Reseat the fan connector at both the motor and control board ends.
- Replace fan: If the fan is noisy, wobbles, or does not maintain speed, replace the fan assembly.
- Control board: If a new fan does not resolve F31, the control board's fan driver or feedback circuit may be defective and require replacement.
