Not cooling and shutting off, indicator light flashes

Within 5 minutes of turning on the air-con, it will turn itself off. In this time it will not have any cooling effect at all. When the aircon shuts off, the power light will flash.

This is possibly either a complete outdoor pc board error or an E-Prom error on the indoor pc board. You can try shutting down supply power completely for a minute and then switch on. These units also have a delay timer system which does not like to be switched on, off repeatedly in a short period. Please also check for reset button on the outdoor pc board. Hope this helps.

Sounds like your aircon is stuck on heating mode. Or. The outdoor fan speed is affected by ambient temperature, or low refrigerant. In heating mode the indoor fan will come on for a while to sense temperature and will then wait for the outdoor unit to pump up pressure and build up heat.

SOURCE: air con indoor unit is flashing 6 times out door is off

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.

It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.

It should measure 5kΩ @ 25°C

Flashing snowflake


The flashing snowflake means it is in the cooling mode, but is waiting for itself to 'time out' after a call for cooling. It should be about a 5 minute delay then should come on automatically. At that poing, the flashing snowflake becomes steady.

Try it one more time and set the timer on your smart-phone to ten minutes before you touch it again. If that time elapses and no cooling and it is still flashing there's possibly a problem in the thermostat that will necissitate replacement.
