Possible Causes
Outdoor fan motor feedback failure, Fan blades obstructed, Low refrigerant causing low suction pressure, Faulty low-pressure switch (if equipped)
How to Fix / Troubleshooting
Safety first: Turn off power before working near the outdoor fan or pressure switches.
Steps:
- Inspect fan: Check that the fan blades are not hitting the grille or debris. Remove any obstructions and ensure the hub is tight on the motor shaft.
- Check motor connector: Ensure the outdoor fan motor plug is secure on the PCB and not burnt.
- Spin test: Rotate the fan by hand; it should move freely. Stiffness indicates bearing failure and need for motor replacement.
- Pressure switch (if present): Some Blaupunkt units have a low-pressure switch wired to the PCB. Inspect wiring and terminals for damage. Do not bypass safety switches.
- Refrigerant diagnosis: If the fan is good and F5 persists, a technician should check system pressures for low charge or restriction.
