The red light is on my freezer also the green one the door has not been left open can you help

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.

My guess would be yellow?

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.

My green light stays on all the time unless I open the door and it needs to get back down to temperature. The red light will come on then and return to normal after 30 seconds to a few minutes if on a hot day. Good luck hope I could help

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

the light tell you if the door is closed properly or not . Close the door tightly and check the lights. Then open it and check them again this will tell you the positiopn of the door for each colour

This means the temperature is rising and alerting you to have it repaired. Make sure no one left the door open and that nothing is keeping the door from closing and sealing all around. If these are okay I would need a little more information like the model number from the tag inside the unit to help figure out what might be wrong.

My wife solved it for me :-) You turn the alarm off with a switch at the bottom. The alarm turns off, but the light stays red for another 4 hours. After that the red light goes off too, and you can turn the switch back on without the alarm going off, if the freezer is back to operating temp.

The alarm should go off when it reaches 0 degrees if not post back

You need to replace this pc board, your unit seems to be short cycling because of a fault on the defrost side of the board.
