Why does one temp. Reading seem correct 53. The other is up to 69?

Sometimes it does take time for things to stabilize. I have had weather instruments take up to a day to get right. Unfortunately, just because something is new does not guarantee it is working perfectly. That's why most things come with a guarantee.

Get a thermometer for both fridge and freezer to ensure temps are correct. Freezer should be around 0F and fridge around 37-38. If temps are correct but display is reading that much differently, control is most likely bad.

seems to me aqua stat or thermistor is not reading temps correctly or temp setting is not correct

three possible reasons
insufficient coolant to make the temp sender unit read correctly
faulty temp SENDER unit
thermostat stuck open
take it in to an accredited service shop with experience on your make of vehicle and have it checked out

Is this a model=>FGHC2342LF Sounds like the freezer=> 240597203 Thermistor may be defective??There should be one in the freezer that regulates the temp and this one may be causing the compressor to run continious and you may not be getting the correct reading from freezer. Have you seen this?

I'll put my bets on a faulty gage...but that's just me.

What is the high side pressure?
Are the indoor and outdoor coils clean?
Indoor and outdoor fan motors working OK?
Ice on the coils or expansion valve?
Is the unit sized correctly for the space?

make sure the display is correct put a thermometor in oven to get correct reading

thermostat problem replace that if you know how to do that or call a technician who will help you

It sounds as if the temperature sensor probe is touching the cold coil inside. The sensor is located in the incoming airflow, in front of the cold coil. It must not touch the coil. This should be visible with the cover off. You can gently bent the sensor away fron the coil, 1/4-1/2" of clearance is plenty.
