Don’t phone, just respond on line

Right the red light is a alarm to notify the temp in the appliance is too warm to store foods.

Typically this mean the appliance is warmer than -12. It may be though the temp was set to -16 it was actually warmer than reported inside.

To confirm with the temp set to -20 the red light has now gone off?

Customer: replied 4 days ago.
Don’t telephone
Customer: replied 4 days ago.
Alarm still on at -20

Ok in placing your hand inside would you agree the temp is -20?

Customer: replied 4 days ago.
Don’t bother. This is a waste of time. Goodbye

No problem most like the fault is with the PCB not detecting the temp correctly, due to this being a budget appliance it is probably not going to be economical to repair as you would be looking at around £100 in labour charges alone.

Should the appliance still be cooling at -20 I would just discard the red warning light, but it would suggest the appliance has a underlying fault and will likely develop a wider fault over time.
