So only the refrigerator side fluctuates? The freezer side never moves?

You either have a thermistor issue or a control board issue. I suspect a thermistor but you would need to rule that out. The thermistors are inside the refrigerator section. You will need to access them and ohm them out. If they test good, the control has a software issue and will need to be replaced. The sensor should read 6.2k ohms at room temp and in a glass of ice water 16.3k. The board is on the back behind the small access cover. If you need to replace it, it has all plug and play connections. It's a very straight forward repair. You can see where all the temp sensors are in the link below.
