In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional refrigerant R22 in order to prevent destruction of the ozone layer.

A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner. Caused from its characteristics, a current limit works on the direct current motor. When replacing the high performance filter or when opening the service board, be sure to stop the fan. If an above action is executed during the fan operation, the protective control works to stop the unit operation, and the check code “P12” may be issued. However it is not a trouble. When the desired operation has finished, be sure to reset the system to clear “P12” error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

TROUBLESHOOTING

Before troubleshooting
1. Required tools/instruments
> + and – screwdrivers, spanners, radio cutting pliers, nippers, push pins for reset switch
> Tester, thermometer, pressure gauge, etc.
Confirmation points before check
a. The following operations are normal.
Compressor does not operate.
> Is not 3-minutes delay (3 minutes after compressor OFF)?
> Does not thermostat turn off?
> Does not timer operate during fan operation?

> Is not outside high-temperature operation controlled in heating operation?

Indoor fan does not rotate.
Does not cool air discharge preventive control work in heating operation?

Outdoor fan does not rotate or air volume changes.
> Does not high-temperature release operation control work in heating operation?
> Does not outside low-temperature operation control work in cooling operation?
> Is not defrost operation performed?

ON/OFF operation cannot be performed from remote controller.
> Is not the control operation performed from outside/remote side?
> Is not automatic address being set up? (When the power is turned on at the first time or when indoor unit address setting is changed, the operation cannot be performed for maximum approx. 5 minutes after power-ON.)
> Did you return the cabling to the initial positions?
> Are connecting cables of indoor unit and remote controller correct?

Troubleshooting procedure
When a trouble occurred, check the parts along with the following procedure.

Trouble > Confirmation of check code display > Check defective position and parts.

For cause of a trouble, power conditions or malfunction/erroneous diagnosis of microcomputer due to outer noise is considered except the items to be checked. If there is any noise source, change the cables of the remote controller to shield cables.

Wireless remote controller type: (For 4-way air discharge cassette type only models)

Confirmation points before check
The following operations are normal.
Compressor does not operate.
> Is not 3-minutes delay (3 minutes after compressor OFF)?
> Does not thermostat turn off?
> Does not timer operate during fan operation?
> Is not outside high-temperature operation controlled in heating operation?

Indoor fan does not rotate.
Does not cool air discharge preventive control work in heating operation?

ON/OFF operation cannot be performed from remote controller.
> Is not forced operation performed?
> Is not the control operation performed from outside/remote side?
> Is not automatic address being set up?

a. Did you return the cabling to the initial positions?
b. Are connecting cables between indoor unit and receiving unit correct?

Troubleshooting procedure
(When the power is turned on at the first time or when indoor unit address setting is changed, the operation cannot be performed for maximum approx. 5 minutes after power-ON.)
When a trouble occurred, check the parts along with the following procedure.

Trouble > Confirmation of lamp display (When 4-way air discharge cassette type wireless remote controller is connected) > Check defective position and parts.

Outline of judgement
The primary judgement to check where a trouble occurred in indoor unit or outdoor unit is performed with the following method. Method to judge the erroneous position by flashing indication on the display part of indoor unit (sensors of the receiving unit) The indoor unit monitors operating status of the air conditioner, and the blocked contents of self-diagnosis are displayed restricted to the following cases if a protective circuit works.
