Sounds like the air filter is dirty. Air flow is restricted and the compressor will shutdown if it gets too cold because the available air cannot warm up the evaporator enough. That could also be the reason it does not heat as well either. Since you do not mention that the air flow is lower than it use to be.

    Thank you for the potential help! The fan motor is probably broken because ice formed all around the A/C and all around the fan inside

We had a similar problem. The timer light would blink 3 times, pause, then blink 3 times again, pause, and so on. The fan was blowing lots of air out, but the air was not cold. The operation light was off.

The technician came and fixed it for free, since it's actually easy to fix. He went to our circuit-breaker box, and cut power (from the box) to the air conditioners for 30 seconds. Then, he restored power - problem fixed!

It's apparently because the air con goes into a "safety" mode when there's a power surge.

How do I get the fault codes up on a Panasonic split air conditioning system CUE24FKR


14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control 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 unless
pressing the CHECK button continuously for 5 seconds or
operating the unit 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.

Note:

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

Fujitsu a/c outdoor model number AOTG12LVC indoor unit economy light flashing continuously, operation light single flash, timer light single flash this sequence repeats


Serial communication error. This means that the indoor unit is not communicating with the outdoor unit usually because the outdoor unit is faulty. You can check the indoor unit by switching it to 'fan' mode and seeing if all functions work normally (fan speed, louvers move as directed). If it responds normally, then it's probably ok so you can turn your attention to the outdoor unit. A common problem with the outdoor controllers is that they are susceptible to bugs, geckos, etc. shorting them out which will mean replacement of the board.

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.

    Fujitsu Inverter ASTA24LCC has flashing "Operation" and sometimes "Timer" lights. I have cleaned filters but the lights still flash. Does anyone know the issue here?


    You may need to open the louver and hold down the Manual/Auto button for 10 seconds to see if you can reset the machine. Additionally, unplug the unit for 30 seconds or so and then plug back in.

    Timer light on fujitsu heat pump flashes not heating


    the light flashing indicates there is a problem. you can try reseting the system by turning the power supply off and back on again 30 sec later, if the same thing happens you need to count the number of light flashers and that relates to a fault code

    FUJITSU Indoor Inverter ASTA09LCC/ASTA12LCC airconditioning - not cooling


    If the operation button is flashing 8 times, the timer light should also flash 4 times in each sequence. This indicates a failure of the PFC circuit in the outdoor unit which basically means a faulty outdoor board and will have to be replaced.
    If the operation light is flashing 8 times by itself, the indoor controller board may have a fault. You can normally test this by putting the mode on the remote to 'Fan' and checking that the controls otherwise work normally - louvers work as directed and fan speed changes correctly when selected on the remote.
    Most likely the fault lies in the outdoor board but you should contact a tech to diagnose correctly.
