The unit is overheated and the safety high limit switch on the heat has shut the unit off. sometimes this means that they are need to be replaced , use an ohmmeter check out the resistance and see if it's still good.

Repeated 3 flash on atmospheric-vent Honeywell gas control valve means temperature sensor failure.
Take apart gas control, and buy temperature sensor if sold separately at AO Smith dealer.

Lg spilt system turns of after 5 mins green light flashes


You need to note the pattern of the flashes, short or long flashes etc.
there is a legend that explains all the possible codes.

Example: 3 long flashes 1 short flash, the legend will say something like hi pressure safety switch
or low pressure safety switch , this could mean dirty coils, inside and outdoors, or bad fan motors either location as well, the compressor may be over heating or overloading, or be gong bad. a capacitor may be the culprit, what you can do is see the fuses and airflows good and no coils blocked etc , notice if any motors stop causing the flasing lockout condition.
