Hello sir LG inverter cassette AC red light 5 time blinking

@InstaromRo 2 года назад

Hi, unfortunately you have this error, the “Units” digit of the fault code is shown by the power led, this is usually Red, but on a few models it is Green. The “Tens” digit will be displayed by one other led, usually the “Sleep” or “Filter” lamp. In any case it is the only error code with 5 flashes, it cannot be confused with a code with the number of tens 5, because the codes with the number of tens 5 start from CH51, which will be 5 flashes and one on the other led.

Sir Ch 60 Error Also explain please

@InstaromRo 2 года назад

Hi, CH60 refers to EEPROM Check sum error. If removable EEPROM, check communication with the circuit board, check PCB for poor soldering. If not, the EEPROM is defective. Replace with the circuit board.

Hello, I checked my wires and they are good, the indoor unit runs for 2 minutes, I have good voltage and then goes back to CH 05!! I went to the outdoor unit and replace the open board and I make sure that all the wires were connected the right way. I turned off the unit nearby and still same problem, what am I doing wrong ???
