When the yellow light is on, is that because the freezer is off? On the switch there is I/O . which means OFF and which is ON?

Green light means that freezer is connected to the mains/electric

Red means that your freezer has not reached minimum working freezing temperature, this is not good news, something may be wrong with your freezer, get it checked by a competent person.
yellow light means that you have switched the fast freeze button on. This yellow switch allows the freezer to run continuously so that the frozen food you brought home from shopping can freeze up quicker. You must not leave this light on for more than 3 hours. It will cause you to waste a lot of electric and will place a lot of stress on the working component in the fridge.

Red light lit on freezer means that is not reaches operating temperature.

Most often the old freezer has three indicator lights.
- Green light : that it is brought to a power source and turned on - Red light : means that the temperature is above -18 degrees
- orange light : pressing the so-called SUPER-switch which means that the compressor is running continuously. The SUPER-button switch on a few hours before you begin deep-freeze foods. Freezing time depending on foods quantity (kg). With old freezer must be careful to turn off the switch S (orange light) when the red light goes out or when foods are frozen, otherwise after a few days may burn out the compressor. You should be following the instructions from user manual.
In new freezer managed by the electronics, this function has a predetermined maximum duration, in order to protect the compressor, and can have different marketing names like "shopping".....

Red Alarm Indicator Light
Under normal operating conditions, the internal temperature of the freezer will ensure the long-term conservation of the stored food. When such temperature rises above a certain level (-12 °C), the appliance will trigger an acoustic and light alarm. The light alarm is a blink red light (Red Alarm Indicator Light), while the acoustic alarm is an intermittent sound.
You can stop the acoustic alarm by pressing the Acoustic Signal Stop Switch once.

When switching on the freezer for the first time, the Red Alarm Indicator Light will blink until the internal temperature has reached a level required for the safe conservation of frozen food.

Fast Freeze function
If more than 3-4 kg of food is to be frozen:
1. Press the Fast Freeze Switch for 2-3 seconds to activate the fast-freeze function 6-24 hours before placing the fresh food in the freezer, the Yellow Fast Freeze Indicator Light will illuminate. The compressor will now run continuously, to ensure that the fresh food is frozen as quickly as possible.
2. It is possible to deactivate the function at any time by pressing the Fast Freeze Switch for 2-3 seconds.
3. Place the foods in the freezing compartments (indicated with graphics).
4. Once the food is completely frozen (it may take up to 24 hours) you can manually switch off the fastfreeze function by pressing the Fast Freeze Switch for 2- 3 seconds and the Yellow Fast Freeze Indicator light will also go out.
5. Move frozen food from the freezing compartments into the other compartments (storing compartments) to make room for another freezing.

If the Fast Freeze Switch is accidentally left on, the fast-freeze function will be automatically switched off 48 hours later. The Yellow Fast Freeze Indicator light will also go out.

I believe that you all understand. If you intend to freeze larger amount of food then certainly a few hours before some shopping switch on the fast freeze function.

You did not specify which lights are on?

• The green pilot light will illuminate to show that the appliance is switched on.
• The red alarm light will also illuminate until the freezer
  reaches the correct temperature.
• If you press the SUPER button than you start fast freeze function and yellow light will illuminate.

I assume that the freezer is on and the green light is illuminated. This means that the freezer is on and energized.
Also, if freezer does not cooling, means that did not achieve the set temperature should be illuminated the red light (alarm).

Set the thermostat for example in position 4th and after that compressor should be start.
If compressor running but not cooling, defective is the system which circulates gas.
If compressor does not start, then is faulty thermostat, compressor or the wiring.

No. It could be green, red, white, IR, and colored light will work if it's the right wattage and the same bulb barrel, then it will workie...he,he,he,he, awesome colored lights in one freezer---never though of that before, wonderful...GB ya. stewbison

Pretty sure that the slide is for winter and summer operation, you are rite, the 3 position is the cold level and the 3 lights (Yellow, Red, Green). the Yellow indicates a caution,"" not at temp or faulty""the Red indicates the unit is active and the Green indicates at temp and operating correct. This unit is old and not much information is available however I hope from my experience, that will help you, any further problems call Russ on 08 95230552.

Hi,

The on/off switch is only for the alarm. Some people do not want the buzzer to sound for them. If your buzzer is going off then the temperature in the freezer is too warm. It usually means the door was not closed all the way or there is a malfunction in the cooling system. Check the door and seal, make sure it is closing all the way around. If it is and the alarm does not stop on it's own then you will need service done on the unit.

This just means that you have power to the freezer.  It's letting you know it is plugged in.
