I have F7 Fault NOT F8

Expert:  George-Allsorts replied 2 years ago.
My appologies, F7 means that you have a cooling system fault

Can you go to the rear of the freezer and tell me from the label again, what refrigerant the appliance is using?

Can you also tell me if the compressor is anything other than warm?
Customer: replied 2 years ago.

Compressor is warm.

It does not say what refrigerant is used

Expert:  George-Allsorts replied 2 years ago.
Can you check if the fan is rotating inside the freezer.. You should be able to hear it as soon as you open the door
Customer: replied 2 years ago.
Yes it is
Expert:  George-Allsorts replied 2 years ago.
Have you tested the internal temperature of the freezer... both when the alarm is sounding, and when it is not sounding?
Customer: replied 2 years ago.
Temperature remains inside and outside as set at 10 degrees
Expert:  George-Allsorts replied 2 years ago.
Ok, we are finally getting somewhere... The temperature inside should be -18 or lower..

The alarm will be sounding to let you know that the temperature of the freezer is getting to an unhealthy level for keeping frozen food

Try lowering the temperature to -18 which is about standard for all freezers.
