Activation Current And Led Blinking 6 Times - LG LTNS16121V /00 Service Manual

. 2 Activation current and LED blinking 6 times (Activation Current)
Blink Blink
6 times blinking (activation current) may occur in a temporal disconnection situation like when refrigerator is turn on/off for 3
minutes.
1. If it's blinking 6 times but there's no a significant difference between the temperature inside the refrigerator and the set
temperature, there's no problem in PCB, Compressor or refrigeration cycle
2. If it's blinking 6 times and problem such as no cooling occurs, it means cycle leakage or cycle clogged (moisture, trash).
Cause: Cycle leakage or clogging, excessive increase in compressor temperature, compressor piston is locked, PCB IPM,
device is burned due to condenser fan defect.
Cause: Over-current protection.
Action: Check PCB output, verify compressor operation, leakage inspection and check cycle clogging (for re-vaccum, 30
minutes in additional vaccum).
