SOURCE: Hitachi RAS-25CHA will not work after power supply -brown outage.

Heya,
I am an ex warrenty agent for Hitachi in Western Australia and I will be able to take you through some tests if you want. But from the sounds of it I think that you will be up for a new indoor PCB as these are the most common things to go when there are power failures. If you would like me to go through it with you let me know. But first where abouts are you in Australia?

I would really call your installers back mate.

If you have anything to measure air temp with I will take you though some tests.

But at this point I would say that your air con does not have any gas and the installers should come back. If they will not come back you should contact Hitachi warranty

Hope this helps

Is the unit responding to remote instruction at all? It does sound like your board is gone. This is usually a capacitor (blue or green and round flat disc) on the pc board, and possibly one of the diodes (small black cylindrical shape with a white line on one side) Often it is the compressor drive relay (rectangular black box) on pc board. If however you have managed to find a replacement board. The plastic heads holding the pc board are released by using a small long nose pliers and pinching the bit sticking through the board. The rest is simply a matter of changing one wire at a time from old board to new board. Or a good method is just to take a snapshot with a camera to refer to regarding the wire positions.

Normally maximum indoor unit carries sealed motor. Hence, replace bearings.

The unit is working but Operation and timer light flash 4 times then timer light flashing 3 times


It depends on the model as some models error codes differ slightly but this is the typical code for operation x 4, timer x 7:
VDD permanence stop protection (Electric air clean)
When the air cleanness monitor trial protection operates 4 times.
> Only clean air permanent stop.
[Diagnosis Point]
The front panel is closed.
The foreign body such as dust doesn't adhere

Panasonic air con - when you turn the air con on it runs for about 3 mins and then the timer light flashes. Air con will not work.


• Once abnormality has occurred during operation, the unit
will stop its operation, and Timer LEDs blink.
• Although Timer LED goes off when power supply is turned
off, if the unit is operated under a breakdown condition, the
LED will light up again.
• In operation after breakdown repair, the Timer LED will no
more blink. The last error code (abnormality) will be stored in
IC memory.
• To make a diagnosis:
1. Timer LED start to blink and the unit automatically
stops the operation.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by
pressing the CHECK button continuously for 5 sec-
onds or without any operation the remote control for
30 seconds.
8. The LED will be off if the unit is turned off or the
RESET button on the main unit is pressed.

When you have the error code, we can work out what to do next.

PANASONIC CS-CU E24PKR fault code H00


H00 No abnormality detected - Normal operation

You may have a problem with the outdoor controller, the indoor controller or both. Power outages can do some strange things to the electronics. Turn the A/C isolator off for five minutes and back on again to be sure the problem is still there. You could also try this:

• To clear memorized error (Protective operation) status
after repair:
1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.

MY FIJITSU inverter is not working correctly, the timer light is flashing continuously and the timer lights flashes 5 times can anyone help pleawe


fujitsu is a good brand.
try one of these two things:

Turn the unit off then on again. After that press test button on remote control (rear side) and look how many times now operation and timer LED flashes. Note that. Then press MANUAL/AUTO button on indoor unit until you hear 3 beeps from buzzer. That will erase error memory.
Switch off and than on unit and see if indication repeat or it is gone. If it is gone, keep using your unit.
If it is repeated post your notes here.

OR+++++++++++++++++++++FOR OTHER MODELS

5 x Operation flash and a constant Timer flash indicates an outdoor unit control error. With this code flashing on the indoor unit, you need to point the remote at the unit and push the test run button. The flash pattern will change to a continuously flashing Operation light and a number of flashes of the timer light which gives more detail on what the error is.

To get the unit to try to restart you need to push and hold the manual/auto button on the indoor unit for a few seconds then reset the mains power supply but leave it off for a minute or so for the unit to power down completely. If you are going to try this make sure you make a note of any error codes first if you have to get someone out to look at it, it will help them a lot.

Hi I have a panasonic split air conditioner. It turns itself off immediately after turning on, the timer button then flashes and that's all.... I have checked for an error code it is H00. I have also made...


Hi Tania,
Have you gone through this checking sequence.? it's from a Panasonic a/c manual. It could be something as simple as a clogged filter. Once you have rectified the fault, you will probably have to clear the fault code as described at bottom below, before it will condescend to work again.

  • Once error occurred during operation, the unit will stop its operation, and Timer LED blinks.
  • Although Timer LED goes off when power supply is turned off, if the unit is operated under a breakdown condition, the LED will ON again.

    seconds) will be heard. If no codes are matched, Power LED will light up for 0.5 seconds and no sound will be heard.

LG aircon operation flashes blinking light 8 times and then shifts to timer light flashes blinking light 4 times


Sounds like a 48 code. (There is no 84 to my knowledge).
Outdoor unit coil outlet (liquid line) thermistor has disconnected or has shorted out.

My A/C unit will not switch on - the timer light flashes 13 times and then repeats this constantly


Check your indoor room and coil temp, may be defective. your ac requires wet service with some gas top up. First service your unit and run. If it runs smoothly, your problem solved. If less cooling short of gas. Tap up gas.
