17.5.27 Outdoor High Pressure Switch Activate (F12) 

Malfunction Decision Conditions: 

During operation of cooling and heating, when pressure 4.5 MPa and above is detected by outdoor high pressure 
switch. 

 
Malfunction Caused: 

1  Dust accumulation on the outdoor unit heat exchanger. 
2  Air short circuit at outdoor unit. 
3  Faulty water pump. 
4  Insufficient water flow rate in system. 
5  Water leak in system. 
6  2/3 way valve closed. 
7  Clogged expansion valve or strainer. 
8  Excessive refrigerant. 
9  Faulty outdoor high pressure sensor and switch. 
10  Faulty outdoor unit PCB. 

 
Abnormality Judgment: 

Continue 4 times in 20 minutes. 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

Troubleshooting:

For safety reason and to prevent component breakdown,
always switch off the power before remove and connect the component.

Check the dust accumulation on the

outdoor unit heat exchanger.

Is the outdoor unit heat

exchanger dirty?

Check the 2/3 way valve.

Check the system water passage.

Is the 2/3 way valve closed?

Is there any water leakage?

Check for clogged

expansion valve or strainer.

Is the expansion valve or

strainer clogged (ice formed)?

Check refrigerant amount.

Is the additional refrigerant

amount filled correctly?

Check the outdoor air

passage.

Is there any short circuit?

Is the water pump working?

Check the system water

flow rate.

Is the water pump speed

adjusted according to system

hydraulic external static pressure?

Check the system water pump.

Clean the heat exchanger.

Open the 2/3 way valve.

Provide sufficient air

passage.

- Replace the faulty water

pump.

- Replace outdoor high

pressure sensor.

- Fix the system water leakage.
- Replace outdoor high

pressure sensor.

- Reclaim and recharge with

correct amount of refrigerant.

- Replace outdoor high

pressure sensor.

- Replace the outdoor unit

PCB (main).

- Replace the outdoor high

pressure sensor and switch.

- Replace the expansion valve

and/or strainer.

- Reclaim and recharge

refrigerant.

- Replace outdoor high

pressure sensor.

- Readjust the water pump

speed.

- Replace outdoor high

pressure sensor.
