Quickone,
If this worked fine before the "recall" and doesn't now, you may want to contact the shop where you had the work done and let them know that they "did something" to affect the performance of the fridge.
Suggest you get a copy of the service manual and look at the diagnostic section.
Service Documents
A couple things to look for are: are you two fans running every 7 - 10 minutes or so for about 2 - 3 minutes.
If you're using A/C try switching to gas. While doing the "recall" they may not have accidentally disconnected one of the heater rods that plugs into the control board (yellow & black wires). This is the "engine" that creates the cooling for the freezer then the fridge.
If your refrigerator is in a slideout, open the top vent and see if the thermostat (about the size of a nickel and usually located on the right side of the fins, has a black and a white wire going to it) is securely fastened to the condenser fins and the spade connectors firmly seated on the terminals of the thermostat.
The service manual also has a method for testing your Thermistor which is located inside the fridge and is on the right side of the set of cooling fins.
Hope this helps,

Mike
