What it means
The manual says: Fan motor Outdoor unit fan motor is anomalous.
Part involved: DC fan motor / fan driver.
Likely causes:
- A strong wind is blowing against the fan, making it turn in the opposite direction. Reorient the unit or shelter it to prevent the wind from blowing against the fan. The fan motor is broken, replace it.
Is it safe?
| Does the heat pump stop? | Partly |
|---|---|
| Severity | Fault — clears by itself when the condition goes |
| Engineer needed? | Yes |
The heat pump keeps running with some functions stopped.
Resetting itself: yes - system restarts automatically when the cause disappears (may run in degraded/back-up mode meanwhile).
Manual reset: not required once cause removed.
What you can check
- Note the exact code shown on the controller and when it appeared.
- Check the outdoor unit is not blocked by leaves, debris, snow or covers and has clear airflow.
- The manual's user steps allow switching the system off and on once to see if the error clears; if the code returns, contact the installer.
- If the code persists or returns, contact a heat pump engineer.
What the engineer will check
- A strong wind is blowing against the fan, making it turn in the opposite direction. Reorient the unit or shelter it to prevent the wind from blowing against the fan. The fan motor is broken, replace it.
Who to ask for: heat pump engineer with electrical competence.
Certification: Qualified electrician / manufacturer-trained heat pump engineer; F-gas if refrigerant circuit is opened.
