Question about Panasonic Heating & Cooling

1 Answer

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 sure both timers are set to 0.00. Can you please advise a fix?? The unit is only a year old...

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.
  • In operation after breakdown repair, the Timer LED will not blink. The last error code (abnormality) will be stored
    in IC memory.
14.2.2 To Make a Diagnosis

  1. 1 Timer LED starts to blink and the unit automatically stops the operation.
  2. 2 Press the CHECK button on the remote control continuously for 5 seconds.
  3. 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. 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. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main unit.
  6. 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. 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. 8 The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.
14.2.3 To Display Memorized Error Code (Protective Operation)
  1. 1 Turn power on.
  2. 2 Press the CHECK button on the remote control
  3. 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. 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. 5 Each press of the button (? or ?) will increase error code number and transmit error code signal to the main
    unit.
  6. 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. 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. 8 The same diagnosis can be repeated by turning power on again.
14.2.4 To Clear Memorized Error Code after Repair (Protective Operation)

  1. 1 Turn power on (in standby condition).
  2. 2 Press the AUTO button for 5 seconds (a "beep" sound is heard) on the main unit to operate the unit at Forced Cooling Operation Mode.
  3. 3 Press the CHECK button on the remote control for about 1 second with a pointed object to transmit signal to
    main unit. A "beep" sound is heard, and the Error Code is cleared

Hi, I have a Panasonic split A C, i think the off timer is set in it by mistake but when i 'm trying to cancel the timer ..it is not getting cancellrd. All the time timer light is blinking. Pls...


A fairly quick solution is to turn the unit OFF & unplug it for 15 - 20 minutes. Once the time has elapsed, plug the unit back in & turn the ON/OFF Switch to ON. During that time out, the electronics should have reset and reverted back to the original factory settings. You should now be able to set the controls as you like.

Hope this helps and thanks for Choosing FixYa.
