9.3.3 Phase sequence error

9.3.4 High temperature protection

condenser

High temperature protection of condenser

Check the resistance of the temp. sensor

according to

Appendix 1

, is it normal?

Possible reason

1. Air or other gas in the refrigerant.

2. Heat exchanger is dirty

3. Outdoor fan or fan blade is defective

4. Outdoor unit is bad ventilation

5. Refrigerant is leakage

6. Outdoor PCB is defective

Replace the sensor

Yes

Phase sequence error

Change the order of the wires to power supply.

Switch on the unit again.

If the problem cannot be solved, the outdoor PCB is defective
