Carrier Cassette Air Conditioner Fault Codes

Advertisements


Once a failure occurs with the indoor unit in operation, the green unit LED flashes at intervals of 0.5 seconds.
The fault code is deduced from the number of times the green LED flashes, blocking unit operation. Between one flash cycle and the next one, a pause of 5 seconds elapses.

    Hi! I have a 60,000BTU/hr Alliance Cassette split type air con unit. The air con wont start but only blinks the orange light on the display while showing error code E8. Once in a while, when I turn it off at the mains, the indoor fan attempts to run, but only very briefly and stops.

    The fault code list I googled only goes up to E6 and 7. Even these two last codes are said to not have been used and that if they show on the display, one must just replace the board.

    What could be the fault?

    Regards.
