Samsung AQV09AWN-X
Hi,
I had a heat problem with an air conditioning AQV09AWN-X. This donīt produce heater and one day the external unit board burned completely.
We replace the external unit control board but now the internal unit gave us the E1-01 error which is a communication error between both units.
But we realize that the internal unit turns on the 220V only for a few seconds and after that the voltage backs to zero and I thought that the external unit board don't have enough time to start the communication and after a few minutes the internal unit gave us the E1-01 error.
I donīt know what I can do to solve this problem, I need some help. Do you have any clue about this problem?
regards

Re: Samsung AQV09AWN-X
When I install a new board we need to introduce an "option code" in internal unit for the external board starts to communicate with internal unit.
Someone know where is this "option code"?

Well, I answer to my question but this can be useful to anyone.
For the unit AQV09AWAN
the option code is
004777-17520C
or also can be
004877-17520C
depending on the board.

Re: Samsung AQV09AWN-X
Anyone has the schematic of AQV09AWAX board ?
My new board has high voltage on it but the low voltage is always zero and the 7805 regulator didnīt work and also the microcontroller and the complete board.

Re: Samsung AQV09AWN-X
Hi again,
I though that the problem is on SMPS module.
Someone has a SAMSUNG SMPS module schematic (don't matter the model)?
