Description
No communication between MICOM MAIN
and PANEL(PC Er) error code will light up
with alarming sounds.
The Freezer Display blinks in the following
conditions.
- when the Freezer temperature increases
abnormally
- when the Freezer Door is being left open
for a certain time with the inside
temperature is high
The Fridge Display blinks in the following
conditions.
- when the Fridge temperature increases
abnormally
- when the Fridge Door is being left open for
a certain time with the inside temperature
is high
When the Compressor fails starting
When there is a IPM Fault error
When ther is abnormal crrunt detected at
the Compressor
When there is a Compressor restriction error
When there is a low voltage error
When there is a over voltage error
How to do Self-Diagnosis
It needs a Oscilloscope to do the error
check. So, it is more realistic checking the
error after replacing Main or Panel PCB.
The inside temperature has risen
abnormally.
See if the door is being left open for a long
time or it there are hot food being put
inside.
When its root causes get cleared, it will stop
blinking after a while.
The inside temperature has risen
abnormally.
See if the door is being left open for a long
time or it there are hot food being put
inside.
When its root causes get cleared, it will stop
blinking after a while.
1. It will stop blinking after a while
short(U,V,W)
2. Check IPM Pins short of Inverter PBA
(No. #1 ~ 26)
3. Check IPM operating Voltage
(under DC 13.5V)
4. Other cases check the COMP cycle etc
1. Check COMP wire connections(U,V,W)
2. Check PCB Bottom side solder(R1)
3. Other cases check the COMP cycle etc
1. Check PCB Bottom side solder(R1)
2. Check Input voltage oscillation
3. Other cases check the COMP cycle etc
1. Check input voltage under AC 55V(if
input Power is AC110~127V) or AC
106V(if input Power is AC 220~240V)
2. Check the Resistor(R309, R310, R311)
1. Check input voltage over AC 155V(if
input Power is AC110~127V) or AC
310V(if input Power is AC 220~240V)
2. Check the Resistor(R309, R310, R311)
