What it means
The manual says: Outdoor unit fan motor 1 error.
Part involved: outdoor fan motor.
When it shows: Fan <100 rpm 20 s after start; after 3 repeats within 60 s compressor and fan stop; 5 repeats -> permanent stop.
Likely causes:
- 1. Fan rotation failure 2. Motor protection by surrounding temperature rise 3. Inverter PCB failure 4. Main PCB failure 5. Fan motor failure.
Is it safe?
| Does the heat pump stop? | Yes |
|---|---|
| Severity | Fault — needs a manual reset once the cause is fixed |
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
What you can check
- Note the code or fault message shown on the controller/Halo and when it appeared; check the heat pump's isolator and consumer-unit breaker are on. Check the outdoor unit is not blocked by snow, ice, leaves or stored items and that air can flow freely around it.
What the engineer will check
- Rotate fan by hand (power off) for seizure/obstruction; check ambient around motor; check fan motor (Parts Information 4); check inverter PCB output (P650: Red-Black 280-373 V DC, White-Black 15 +/-1.5 V); replace fan motor/main PCB.
Who to ask for: Heat pump engineer; casing removal only by persons competent with R32 (A2L); refrigerant-circuit work requires Cat I/II F-gas certification (I&M p.75 warning).
Certification: F-gas Cat I/II for refrigerant work; electrical work by competent person.
