I have an old indesit freezer with green red and yellow lights in a narroe row at top of door which ones set it on but don't fast freeze

Could you please recheck for the model number. R134A is a reference to the coolant used in the freezer mechanism.
Orange is often a reference to the 'Fast Freeze' function being turned On. Green is showing the freezer unit is at the correct temperature. Red is warning the freezer is Too warm. Some freezers are fitted with an 'Economy' function where the freezer can be run at a lower power level when not used regularly such as when on holiday.

The compressor won't burn out just because it's running all the time. The plastic fascia pops out easily from behind(take the little panel off on the side) Set the thermostat to the middle of its range and switch the fast freeze off.

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 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.

Is it a red light? If so it's not reaching temperature (the alarm is about -12c) If it's a yellow light, you've accidentally switched on "fast freeze". If it's a green light it's just the power supply light.

If the freezer has a condensor coil thry cheaning it. Hope this helps. Wally

Normally there is a Green light showing that power is on

A Yellow one for fast freeze and a Red one for under temperature

The outer casing is well insulated from the inside otherwise the freezer motor would run none stop without cooling the contents so the temperature of the outside casing will reflect the room temperature not the intenal

I used to sell freezers.the green light tells you the mains is on and the freezer should work.The red light is to inform you the freezer is not low enough temperature,and the orange light is a fast freeze light to over ride the thermostat for use when introducing fresh food.It should not be used for prolonged periods as it may burn out the compressor although in your case you already have a problem and should seek advice or buy another freezer.If you get a cheap freezer thermometer it should confirm what I am saying.
