Part involved: COND OUT Sensor of Outdoor Unit breakaway Error.
When it shows: Unit self-diagnosis: COND OUT Sensor of Outdoor Unit breakaway Error.
Likely causes:
- Refrigerant-side temperature sensor open/short circuit, detached or mis-located; connector or PCB fault.
- Engineer checks per Samsung service manual: Check sensor connection status, sensor location and sensor resistance against the Samsung resistance table (103 or 204 type); replace sensor or PCB if required.
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; then contact your installer or Samsung service; Samsung manuals do not describe a homeowner reset for this code.
What the engineer will check
- Check sensor connection status, sensor location and sensor resistance against the Samsung resistance table (103 or 204 type); replace sensor or PCB if required. Any work inside casings, on PCBs, wiring, sensors, pumps, valves or refrigerant is engineer-only.
Who to ask for: Heat pump engineer (Samsung-trained).
Certification: Competent electrical worker (BS 7671).
