Trouble Shooting
Remove the MAIN PCB CN70 and CN7
connectors from the MAIN PCB and
read the continuity between BROWN ↔
ORG wires.
(It differs according to the energy
consumption.)
When it reads 0 Ohm, check the Heate
short and when it reads ∞ Ohm, chec
if the Wire/Thermal Fuse or the Bimeta
is Open.
The voltage between MAIN PCB CN31-
"1(WHT) ↔ 2(WHT)" should be within
0.5V~4.5V.
The voltage between MAIN PCB CN30
"5(ORG) ↔ 7(Gray)" should be within
0.5V~4.5V.
The voltage between MAIN PCB CN30
"4(RED) ↔ 7(Gray)" should be within
4.5V~0.5V.
The voltage between MAIN PCB CN72-
"9(S/BLU) ↔ 10(GRY)" should be within
7V~12V.
Check the soldering status of the
inverter PCB.
(Check if any parts have short-
circuited). Check if the DC 16V output i
less than 13.5V. Check the Comp and
Cycle.
Check the compressor wire
connections. Check the soldering statu
of the inverter PCB. (Check if any part
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 the input voltage. (This error occur
when the input voltage is AC 106 V or
lower.)
Check the input voltage. (This error occur
