An air conditioner that turns on and off by itself may be following a normal thermostat cycle, but frequent short cycling is a warning sign. Timer settings, sensors, voltage instability and protection modes can all be involved. For a technical inspection, contact our air conditioner technician.
Because several systems can create the same symptom, a structured diagnosis is more reliable than replacing parts at random.
