    Just looked for a list of flash codes throughout the manual as well as on the main cover panel. Nothing there... Looked on the net but still can not find anything? Any idea where I could find a list?

If it's winter, you may need to get rid of ice built-up inside that's keeping the fan from turning. Turn the power off AT THE FUSE BOX, open the top of the unit by removing the 4 screws, pour boiling water onto any ice at the bottom until melting, dry with hair dryer a bit, then turn unit back on.

I don't know if this is the proper technical solution or not but my unit was having the same issue. I cleaned it checked fuses made sure the cover was properly in place and nothing worked. As a final thought I went to the home fuse panel and tripped the breaker for the unit, waited about 30 seconds and turned it back on. I did this with the unit set to off. When I came back and turned it on, it is working properly with the operation light solid red.

Locate the manual, or the wiring schematic (usually located on the main cover panel inside for the unit.) and look at the flash codes.

This will tell you what the 5 flash and single flashes mean.
We can then help determin what needs to be done from there.

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.

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.
