General Inverter AOH12LSAC

[Debonair Spain]

Hi Everyone can anyone help, i was called to look at a General Inverter ( Fujitsu ) and found that the system would run for approx 3/4 mins before going into a fault mode and the red LED on the outdoor board flashed 22 times does anyone have any info on error codes or a manuel.

The unit was installed in 2002

Thanks

Will try and find out next week for you, did you get the indoor unit error code display patterns?
They have two levels of display on the indoor unit, you need note the first display then press the test run button on the remote (aim it at the unit of course!) and the flash pattern on the indoor unit will change showing the second part of the error code display.

Thanks Nike123 will keep you informed, the client has gone back to England and cannot access his home until he is back.

You need to count the number of times the light goer out not on. The closest I can come to is 21 offs which is abnormal voltage at active filter module. This is a DC device which amplifies the voltage to about 360 volts DC up to 380 volts DC. It refers to the output voltage so you need to test this, usually a yellow & a blue wire.

Hi Ozairman sorry it has taken so long, client went back to the UK just to let you know that the first part of the error code is 8 flashes on the red lamp with the green one flashing constantly. The second part of the error code is the red lamp flashing constantly and the green lamp flashes 3 times.

Any ideas
