Troubleshooting

Perform troubleshooting according to Table 3-1.

Table 3-1 Table of Alarm Troubleshooting

Fault Phenomenon

Possible Causes

Handling Method

Equipment does not
start up

Equipment does not connect to the
power supply

Check the input voltage

High pressure alarm

Insufficient condenser air flow

Clean away the alien objects on the coil surface or near the air
inlet, and check the fan speed regulation function of the
control board

Condenser fan does not run

Check  if the cable connection between the control board and
outdoor  unit  terminals  is  loosened,  check  if  the  outdoor  unit
cable  connection  is  loosened,  and  check  if  the  condenser
pressure sensor is  normal
