Whirlpool Electronic A class upright freezer. Has stopped freezing: Acoustic Alarm mute button and Fast Freeze buttons are lit.

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.

Warning light (red)
If the temperature warning light (4) lights up, it
indicates that the temperature within the freezer has
reached a level where the safe food storage is no
longer ensured. When the freezer is first switched on, the warning light will stay on until the temperature has dropped to
a safe level for the storage of frozen food.

Temperature acoustic alarm
This appliance incorporates an alarm which gives off
an audible signal whenever the warning light comes
on. This signal can be temporarily stopped by
depressing the push button for fast-freezing (6).
The fast-freezing push button can be released as
soon as the warning light is off.

Open door acoustic alarm
This appliance also incorporates an alarm which
sounds if the door is left open for more than 60
seconds. The signal will be stopped when the door is
closed again.

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.

In my opinion, since your going for the fast freeze mode, your freezer sets to its lowest operating temperature to fast tract the freezing process.

and about the noisy clicking sound it is probably a thermostat or relays depending on your system which starts and stop the compressor.

i think your freezer is just doing fine.

check the engine and pipes.cooler

The light indicates the need for a new battery (9V)

-18c is about 0 F. it shold be cold enough to freeze you know what.
you might want to turn the tempture up a little.

JennyT just trying to help with this. I assume this is a self defrost model. If so then is there an ice build up on the back wall? If so then the unit isn't defrosting. That is why pushing the Fast Freeze button is no longer working. You can get by however. Remove all the food from the freezer, put a vacumn in the freezer and shut the door. Turn on the vacumn, this will pull the warm air thru the freezer and in 30 minutes to an hour it will be defrosted enough to work until you can get someone to replace the 1 of 3 parts that the defrost system uses. The vacumn is what I use to defrost my nonself defrosting freezer. Sorry I couldn't be of more help.

Where is the fast defrost button on Kenmore chest freezers?
