Does the red light on permantely mean the freezer is knakkered

Green light usally means that the freezer is in good working condition. Red light means the door is slightly open and wasn't shut properly. Sometimes the seal on the door has gotten old or twisted.

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".....

It's a temperature warning that the freezer is no longer at the correct temperature. Check all is clean and working, door seal intact etc. If short of gas, probably time to get a new one!!! Bet it won't last 18 years this time though!

Starting the Appliance
Insert the plug into the wall socket. 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.

Alarm Light
The red alarm light will illuminate when the temperature in the freezer is higher than the thermostat setting. This alarm light will illuminate if:
- The appliance has just been started.
- Fresh food has been put in the freezer.
- The lid has been left open, opened frequently or open for too long.
The red light will go out when the freezer has returned to the correct temperature

Mean that the comp is not working

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.

two reds and green are the auto max freeze on indecators the reds go off one at a time when unit drops to safe temp mode.also means unit needs defrosting manually when too much ice is present.

Is this just a "Power-on" light to let you know it's plugged in and has power? This is probably just a "neon" (although the actual gas inside is hydrogen for the green color) bulb and sometimes they will do the flickering thing literally forever. In a way it's a good thing as it makes you look at it. If it really concerns you, or if it is actually a warning that something is going wrong (it should say in the manual, you DO have the manual don't you?) have it fixed under the warranty.

red light flashing on servis fridge freezer

I cannot find any manual or information on the 3 lights. I would assume that the green light means everything is OK, the red means current problem, and the amber means manual defrost is due. Sorry, this is the best I can do. Later.
