Malfunction display: High/Low pressure sensor error

Pressure sensor error

The plug

on pressure sensor is correctly

connected to the socket on

mainboard, is it?

Measure the

DC voltage value between black

line and green line of the sensor: is it

OK?(0.5~4.5V)

Replace the mainboard of outdoor

unit

Check the orientation of

plug and socket

Replace the pressure

sensor

Yes
