Daewoo FRSU20DAI side by side fridge freezer Beeping - Error C1 AND F3

Hi,
I have a Daewoo FRSU20DAI side by side fridge freezer and since the moment you turn it on, it will beep every second.

When you check the error i can see C1 and F3

Sometimes the F3 goes away but the C1 always stays.

The symptoms are that sometime during one of its cycles, it will stop cooling.

I have checked the manual online and i cant seem to understand the error codes.

What can be the issue.
Can anybody help?

Any suggestions are most appreciated.

The link for the manual can be found below

Thank You

“F3” error
Cause : in case defrosting return is done by time limit of 80 min
Check point : Measure the resistance between both terminals of the defrost heater.
(Assembled with evaporator)
If the resistance is ∞Ω (disconnected) or 0Ω (short) change the
“C1” error
Cause : in case comp. works for over 3 hours when D-sensor temp. is over -5℃
Check point : Refrigerant leakage

Thank you for your reply.

I already read that information from the manual but it seems to cut off about the F3 error.

It says
"If the resistance is ∞Ω (disconnected) or 0Ω (short) change the "

Change the what? It seems they missed a word out.

Also can this be the reason why the fridge is beeping every second?

Thanks

check the resistance of the sensor- unplug it off the pcb- best way is to have the fridge freezer switched off for a day and check all the sensor values are similar as theyre at te same temperature
it does say if the cooling operation is too long then possibly short of gas
a quick way of identifying this is if the compressor body is hot- checkthe condenser coil at the back is clear- a can of compressed air will clear dust build up

Thank you for your response.

I will give this a try and report back.

Many Thanks
