Troubleshooting
Check the compressor wire
connections.
Check the soldering status
of the inverter PCB.
(Check if any parts have
short-circuited).
Check the Comp and Cycle.
Check if the compressor
and the Cycle is normal.
Check the input voltage.
Check the soldering of the
inverter PCB.
(Check if any parts have
short-circuited.)
Check Input voltage. (This
error occurs when the
input voltage is below
voltage or lower.)
AC 53V(Input power AC
110~127V) or
AC 106V(Input power
AC 220~240V)
Check Input voltage. (This
error occurs when the
input voltage is below
voltage or higher.)
AC 155V(Input power
AC 110~127V) or
AC 310V(Input power
AC 220~240V)
Voltage between MAIN
PCB CN 30 #2 AND
#3 should be within
4.5V~1.0V.
Check the connection
between MAIN PCB CN02
and WIFI Module.
