What it means
The manual says: Error on DC fan (Non-operating).
Part involved: Fan motor.
When it shows: Unit self-diagnosis: Error on DC fan (Non-operating).
Likely causes:
- Fan motor fault, obstruction (ice/snow/debris), motor-to-PCB connection, fuse or supply fault.
- Engineer checks per Samsung service manual: Check the DC fan in the hydro unit and its connection.
Is it safe?
| Does the heat pump stop? | Yes |
|---|---|
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
Resetting itself: unknown.
Manual reset: unknown.
What you can check
- Note the full error code shown on the controller; check the heat pump breaker/isolator in the consumer unit is ON; check the outdoor unit is not blocked by leaves, debris or snow and air can flow freely; then contact your installer or Samsung service; Samsung manuals do not describe a homeowner reset for this code.
What the engineer will check
- Check the DC fan in the hydro unit and its connection. Any work inside casings, on PCBs, wiring, sensors, pumps, valves or refrigerant is engineer-only.
Who to ask for: Heat pump engineer (electrical).
Certification: Competent electrical worker (BS 7671).
