Trouble Shooting
Check the soldering status of the
inverter PCB. (Check if any parts
have short-circuited).
Check if the DC 16V output is less
than 1 3.5V.Check the Comp and
Cycle.
Check the compressor wire connec-
tions. 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 invert-
er 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)
