Unable to adjust the temperature in Maytag refrigerator.

I have a Maytag refrigerator, mod # RTT1900E, and the temperature in the refrigerator section is too cold. The unit has two plastic dials to control the temperature in the freezer and refrigerator. The freezer section seems to be adjusted OK. However, the plastic dial for the refrigerator section won't turn. I am afraid it will break if I twist it more than I have already. The 0-9 range on the dial is set at 3, while the coldest setting is 9.
There is a screw that holds the plastic dial in place. When I removed the screw and tried to remove the plastic dial, only one side can be pry-ed downward with the right side held in place by something.
Can't find a parts list so don't know how the dial is designed and why the control doesn't work.

Here is a link for the parts list diagram for your refrigerator on the Sears PartsDirect.com website:

Maytag Refrigerator RTT1900EAE

The Fresh Food Compartment page has the control parts illustrated for this refrigerator. A portion of that page is shown in the image below. The refrigerator control knob is attached to the cold control thermostat (KEY 18). The freezer knob controls the damper (KEY 3). The control rod (KEY 5) connects the freezer control knob to the damper. You could have a damper that is stuck in the full open position. This could be causing your freezing condition in the refrigerator. You can try adjusting the freezer knob to see if that damper will close to keep more cold air in the freezer. If you are getting a large amount of cold air flowing from the freezer into the refrigerator and that damper cannot be adjusted then you will probably need to replace some components in that control system. If the freezer control system is working okay, then you may need to replace that temperature control thermostat. You can order parts from the
