Sytem will beep every three hour or when we open the main door

What is the exact model number? This may be an issue with the cables that connect the door to the power supply.

try opening the door.leave it open.unplug the fridge for at least 5 minutes, no less,with the door still open.after that,plug it back in.wait for it to beep.then close the door.
this would reset the door alarm,which beepes when the door isn't properly closed.
also you should wait 24 hours between changing the temperature or it can mess up your fridge.!

Our garage door opener has a safety beam across the floor which prevents the door from closing on objects which are sitting there. This safety feature also makes an annoying beeping sound each time the beam is crossed. This tutorial will show you how to disable the beep, but still keep beam functional. https://www.youtube.com/watch?v=Cn_vGe_7_x4

Hello,


Sounds like you have a bad door switch. Depending on the age of the fridge, it might still be under warranty. If it's not, then you might be able to access the door switch yourself and pull it out & replace it.


Good luck......

does ur car has a burglar alarm?

on the main circuit board on top of the fridge is a button with "test" on it. hold that in for a few sec, it should start beeping at you. push it again and it will beep again, do this about 4 time till it goes quite. this may fix it but the reason for it is prob your sensor is covered in ice, you need to leave it off with the doors open. there are 2 drain pipes at the back of the fridge ( bottom ) defrost it till no more water comes out of these, when you think its done, leave it for a few more hours and if any water comes out your not defrosted yet--- mine took almost 3 days.

I held down the clear button for three seconds, it unlocked but still showed the lock button lit. It began beeping over and over. I opened the door and pressed the clear button again for three seconds. It stopped and the oven works just fine now. In fact, I used it right after I got it cleared out.

Ya what the ????
Not shure what to tell you, first I would see if leaving unplug for a day would solve your problem, to me sound like main board is defective, also try by opening the door a closing it a couple of time, just in cass a switch is jam open.
