We have a LG mini split wall mounted combo air conditioner/heater. We had the heater on and it stopped heating. The amber star light is blinking twice and then the green power light flashes once. The blinking lights keep cycling. Model #LS360HV3. We have checked the manual and nothing regarding this issue. Filter, batteries, thermostat all seem to be good

Hi Cindy, thanks for question

Your LS360HV3 showing 2 amber blinks and 1 green blink usually means a system fault like sensor failure, outdoor-indoor communication error, or refrigerant/pressure issue. Heating stops to protect the unit. Try a full power reset and check wiring, but if blinking continues, a technician must test sensors, refrigerant levels, and the outdoor PCB.
