LG Split System Air Conditioner Error code = C6 or CH06 LG AC Fault Definition = Excessive current at inverter DC power circuit - DC Peak Power
Flashing Light = 6
Display = Indoor Outdoor
Indoor Operation = SHUTDOWN
There are several things that can cause this,, first step is to check all wiring connections, but this can be pointing to a more major issue, the AC to DC transformer,,
It is a experienced tech kinda job

DescriptionError 09 checks lower PCA memory locations during the power up test sequence. If a fault isfound during the power up test sequence, error 09 will be displayed. This error code is only usedon products utilizing the dual microprocessor system.Possible Causes1. This error message almost always indicates a lower PCA problem when it is consistentlydisplayed. Failures causing this error message to be displayed are rare.Possible Remedies1. If the error message is consistently displayed when the unit is powered up, the lower PCAshould be replaced. It is possible to see this error message displayed intermittently due toexternal causes. If the units A.C. input significantly dips during the power up test sequencethe test could fail resulting in this message being displayed. Treadmills operating onnon-dedicated A.C. circuits may see this message displayed on an intermittent basis.God bless you

Precor Error 01, Memory, RAM, EEPROM Test Error Probable Cause This error message almost always indicate an upper PCA problem when they are consistently displayed. Failures causing this error message to be displayed are rare.
Corrective Action If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced. It is possible to see this message displayed intermittently due to external causes. If the units A.C. input significantly dips during the power up test sequence the test could fail resulting in this message being displayed. Treadmills operating on non-dedicated A.C. circuits may see this message displayed on an intermittent basis. Precor Error Code 01

Precor Error 03, Memory, RAM, EEPROM Test Error Probable Cause This error message almost always indicates an upper PCA problem when it is consistently displayed. Failures causing this error message to be displayed are rare.
Corrective Action If the error message is consistently displayed when the unit is powered up, the upper PCA should be replaced.

Precor Error Code 03 E03 EEPROM Test Error

If your Sony camcorder displays a tape transport or mechanical error code always try resetting the camcorder. This is done by removing the battery or ac power, wait 10 seconds, reapply the battery or ac power and try again. If it still goes into error try another tape. The camcorder will not always display an exact error code. Sometimes you may see an error message such as, "Reinsert the cassette", on the LCD screen. This is the camcorders way of saying, "Take the tape out and try again." Try reloading the same tape as well as a new tape. If the camcorder is still going into error this means it is time to send it in for service or repair.
The camcorder may also sometimes display a "Reattach Power Source." This is the camcorders way of saying,"Try resetting my system,so I can try again." Many people mistaken this error and think they have a problem with the battery or ac adapter. This is not true and has nothing to do with your battery or ac adapter. Reset the camcorder by removing the battery or ac power, wait 10 second, reapply the battery or ac power. If the error reappears the unit needs to be serviced or repaired.

Dear Sir:

Hello I hope you are o.k

I wil give some tipoe with this Error code:
Error 09 - Lower PCA Memory Test Errors
Description
Error 09 checks lower PCA memory locations during the power up test sequence. If a fault is
found during the power up test sequence, error 09 will be displayed. This error code is only used
on products utilizing the dual microprocessor system.
Possible Causes
1. This error message almost always indicates a lower PCA problem when it is consistently
displayed. Failures causing this error message to be displayed are rare.
Possible Remedies
1. If the error message is consistently displayed when the unit is powered up, the lower PCA
should be replaced. It is possible to see this error message displayed intermittently due to
external causes. If the units A.C. input significantly dips during the power up test sequence
the test could fail resulting in this message being displayed. Treadmills operating on
non-dedicated A.C. circuits may see this message displayed on an intermittent basis.

Thank you in advance, sincerely. Blessing.

Dear Sir:

Hello, I am glad that you contact us.

I will give some Tips:

1) Your Error C is for Troubleshooting, only that message, is must be special some times.

2) Your Error C, has some interpretation depend of the factory.

3) Example: E 01: Mean Replace VSD( Variable Speed Drive) to due some Microprocessor Chip Failure: The Option will be replace Board VSD, but you must contact to the Company for to Fix the Board.

4) The another Alternative: If your equipment has Servo Motor:the enconder is Malfunction: You must Re-Start Machine, and follow again. If the problem persist, You must exchange: a) Servo Motor b) or The Drive Board.or Both.

5) The following alternative is:
Description
Errors 00 through Error 04 check upper PCA memory locations, RAM memory locations and
EEPROM checksum during the power up test sequence. If a fault is found during the power up
test sequence, the appropriate error code will be displayed.
Possible Causes
1. These errors messages almost always indicate an upper PCA problem when they are
consistently displayed. Failures causing these error messages to be displayed are rare.
Possible Remedies
1. If the error message is consistently displayed when the unit is powered up, the upper PCA
should be replaced. It is possible to see one of these messages displayed intermittently due
to external causes. If the units A.C. input significantly dips during the power up test sequence
the test could fail resulting in one of these messages being displayed. Treadmills operating
on non-dedicated A.C. circuits may see these messages displayed on an intermittent basis.

I hope that you can resolve this, and take your final step.

Thank you in advance, sincerely. God bless you.

37,0XX.xx Errors - PEST Faults
AC power supplied by power sources such as uninterruptible power supplies
(UPSs) or DC-to-AC inverter systems may not supply correct voltage to
properly power up the printer. Likewise, other devices sharing the same AC
circuit can cause AC voltage sags that cause the printer to fail its AC heater
PEST tests (Print Engine Self Test). The printer may produce any of the
following disconnected heater errors:
■ Printhead jet-stack 37,002.47 or 37,003.48

Error Messages and Codes
■ Reservoir heater, 37,004.40 or 37,005.41
■ Drum heater error 37,006.42
■ Preheater error 37,008.44
■ Ink melters errors 37,009.45 thru 37,013.40
The printer includes several heaters powered by AC. The printer itself can
power up despite insufficient or irregular AC voltage but it may fail its AC
heater tests. This is due the test not measuring sufficient current flowing
through the heater at the moment the test runs.
Devices sharing the printer’s AC circuit shared, such as a laser printer, a
coffee maker, or a space heater, may be placing heavy intermittent demand
on the AC circuit. This sudden inductive demand creates momentary AC
voltage sag that causes the PEST test to fail.
Verify the AC power source prior to troubleshooting these errors. For wiring
diagrams to aid in diagnosing PEST faults, see “Wiring Diagrams” on
page 10-1.
8400/8500/8550/8560 PEST Description
37,001.46: Generic PEST error. Something went wrong during the PEST process.
37,002.47: PEST Error - Printhead Left jetstack disconnect. The left jetstack is
not drawing the expected power from the supply.
