Hello and welcome to Just answer my name is ***** ***** will see if I am able to help you with this.
It sounds to me like your refrigerator may have kicked over to defrost mode because the freezer had frozen up. The fan motor may have been hitting ice around the fan blades causing the noise. That would be a good indicator why it is working again once you unplugged it and plugged it back in. I can look over the manual and see what I can find out in regards ***** ***** power interrupter if you would like. Just to check your appliance is running correctly right now right?
There is a heating element in your freezer on the coil which is taking the ice off of that. That is why it keeps bouncing back and forth between 0 and 13 degrees. It will run for so long and then the element will warm up. Your defrost mode will go in and out periodically so there is nothing to worry about with that.
Honestly I have searched around for information that would cause the fridge to heat up that hot because obviously that is not normal at all. I even called some service workers to make sure I wasn't missing something and none of them could figure it out either. I do know though when electronic controls experience a power surge, they stop working until the controls are reset. The reset is to unplug and leave off for around a minute and then plug back in. So it could have been that. Also of course there are the fans and such that could have been a problem but since it is now cooling down I wouldn't think that either. I am for sure that the coils had to have been really dirty to have froze up and stop the cool air from coming in and when you unplugged it certainly jolted the automatic defrost to kick in. As far as preventive maintenance I would suggest to keep the coils clean and clear of debris. As well as checking to make sure the fan is moving and operating properly. Those are main things to keep the fridge and freezer cold or cool. I certainly hope that you don't have this issue again but in the event you do we are here all the time. You are always more than welcome to follow up with me at anytime.
Oh I totally understand I don't want for you to have to go through that either. I would assume the noise was coming from either the evaporator fan or the condenser fan but when you reset it by unplugging and plugging back up it jump started those as well. Since its working correctly at the moment its hard to have you trouble shoot the areas that could have been a problem possibly. As I said before though you are always more than welcome to come right back to this us and I will help you.
