Solution
Select the right mode and set proper temperature and speed.
Check if there is any obstruction at the air inlet and outlet
Check if the surface of the condenser is too dirty
Check if it is short of refrigerant and if the high and low
voltage is within the normal range
When running in an environment with high humidity, water
drops may form on at the air outlet and core surface, which
is a normal physical phenomenon
Check battery for low voltage and verify the power source is
either DC 12V or 24V
Check if the low voltage protection value is too high
Check if the sensor at air inlet / outlet is plugged in correctly
Check if the display temperature is higher than normal
ambient temperature. If it is, change the sensor.
Check if the fan is correctly plugged in. Connect the fan with
a separate 12V or 24V DC power source. If the fan doesn't
work, replace fan.
Check if it is short of refrigerant.
Check if the high and low voltage is within the normal range.
Check if the condenser is too dirty - so that heat dissipation
is adversely affected.
