Nibe High-Pressure Stat (518288) (NEW PART N* 060423)

• Part Number: 518288 (NEW part number 060423)

• Description: High-pressure switch (often called high-pressure stat or cut-out switch)

• Function:
  This component monitors the refrigerant circuit pressure in your NIBE heat pump. If the pressure exceeds a safe limit, it cuts off the compressor to prevent system damage. This helps protect against issues like blocked coils, insufficient cooling, or refrigerant overcharge.

• Typical Application:
  Used in certain NIBE air source and ground source heat pumps — exact compatibility depends on the model and refrigerant type.
  Some models where part 518288 may be used include:

  • NIBE F1330 - 60kw
    

  • Certain ground source models (like F1145, F1155, depending on configuration)

🔧 Installation and Service Notes

• Replacement requires:

  • Refrigerant system handling (likely involves pressure release, reconnection, and recharge).

  • Professional tools and knowledge (because it’s connected directly to the refrigerant circuit).

• Signs it needs replacement:

  • Repeated high-pressure error alarms, even after system reset and checking for airflow/brine flow issues.

  • Visible physical damage or corrosion on the switch.

  • Faulty readings confirmed by a technician.

If you are replacing this part, make sure it’s done by a certified F-Gas qualified technician, as handling refrigerant is regulated.
