Once you nail down the issue you can easily call in a professional, or fix the issue yourself.
Cassette Fault Codes
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.

Troubleshooting
Aircon will not start:
- The main switch is switched OFF, place the switch in the ON position.
- The fuses on the main switch are burnt out; replace the fuses. ( this operation need to be carried out by qualified personnel only).
- Wait for 3 minutes: protection against frequent compressor cycling is ON.
- Selected temperature is higher than the room temperature (or lower in the heating mode).
The unit emits unpleasant smells:
Unpleasant smells can accumulate on the air filters and then be dispersed into the room during air conditioner operation. Switch the unit OFF and contact an authorised service centre to have the filters cleaned. Restart unit in the ventilation (fan only) mode and open windows to change room air.
The unit makes strange noises:
Occasionally the unit makes strange noises at start-up, during operation or when it has stopped. These are generally due to the effect of temperature changes on the plastic parts.
Air conditioner is not supplying enough cooling (or heating):
- Air cannot circulate freely.
- Dirty filter reduces air quantity circulating.
- Filter must be cleaned by skilled personnel only.
- Doors and/or windows are open.
- Fan speed has been set to ‘low’.
- Air flow direction is not correct for optimum ventilation.
- Selected temperature is not correct.
P (Green LED) indicator is flashing:
System malfunction. Contact service organisation after having ensured that:
- Air circulation is not obstructed.
- Outdoor unit coil is not obstructed and causing severe reduction of air circulation.
- Condensate drainage tube is not obstructed.
As regards fault codes to be communicated to the after-sales
Q (Red LED) indicator is illuminated:
In the heating mode, the LED switches on to indicate an active defrost condition.

Hi, our aircon is inverter 40ccv360308
Ceiling cassette.
Theres an error code P3 in indoor and P6 in outdoor. Tnx
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.
Ronald (Blantyre, Malawi)
