if you turn the freezer off for some time then on again the red light has to come on as an indicator for high temperature it goes off by itself when the freezer attains the required temperature according to the thermostat settings ,that is the lower the settings the faster the red light goes off. the orange light indicates super cooling and the green light indicates power supply.if you turn the two lights off and the freezer still works without the green light on that means that the bulb for the green light is faulty and you don,t need to worry
