When the refrigerator was delivered, I read the manual and it states that the unit should be plugged in and set to high after 5 hours and wait 2 more hours before setting it to the desired level and putting food in. I did follow the instructions.

After two hours of letting it run, I noticed that there's an ice build up on the back wall of the refrigerator compartment which I never experienced before. When the compressor stops running, the ice will melt and it will become moisture.

I called up Panasonic's customer service and gave them the model number and I was told that the condition isn't normal so they scheduled a technician from an authorized repair center to check my unit. But I decided to have the unit replaced with another brand new one of the same model which the dealer agreed right away. Unfortunately, it still has the same issue. So I agreed to have the technician from the authorized repair shop to check my unit.

According to the technician, the ice and moist build up is perfectly normal. He explained that the reason the back wall wasn't flat at all was due to cooling coils sitting behind the uneven surfaces to provide cooling to the refrigerator compartment. He explained that the non-frost that we are using before relies on a fan to blow cold air from the freezer to the refrigerator compartment and the single door fridge we have relies on the freezer to provide cooling to the refrigerator compartment since the freezer and refrigerator are in one casing.

Since his explanation is reasonable, I still want to get some opinions from people here. Is it normal for my brand new refrigerator to have ice and moist build up in the back wall of the refrigerator compartment?

I uploaded two photos. The first photo shows moisture build up when the ice has melted when the compressor is in the off state while the second photo shows the ice build after the compressor has run for some time.

Lastly, the bottom part of the back wall has a drain hole similar to the freezer compartment where water can drain into a container just above the compressor at the rear of the refrigerator.

Any information will be highly appreciated.

I recently bought a brand new Panasonic No Frost Inverter refrigerator (NR-BP242VS).

I plugged it in around 11:00 AM and waited about 3 hours before putting containers of water in the freezer to make ice. The refrigerator was set to 5, and the airflow control was set to Normal.

Later, after 10 hours, when I checked one of the containers on the second freezer shelf, I noticed that a small amount of ice/frost had formed on the bottom floor of the freezer compartment. The frost/ice is only on part of the freezer floor and not near the door. But the first layer or tray doesn't have any ice buildup.

Since this is a No Frost refrigerator, I'm wondering if this is normal during the first day of operation while the refrigerator is cooling down, or if it's something I should be concerned about. I also checked the water tray/container at the back of the refrigerator, where I thought defrost water would collect, but it has no water in it.

Has anyone with a Panasonic No Frost Inverter refrigerator experienced this when their unit was brand new? Did the frost/ice disappear on its own after a day or two?

Thank you, please helpppp!!

The fridge door also makes a loud sqeaking noise on opening and closing. WD40 on the hinges just makes the noise louder.
