Question about General Electric GSH25JSXSS Stainless Steel Side by Side Refrigerator
If you are sure that the problem is temperature control, replace the control assembly. Before replacing control assembly I suggest checking the defrost system that is often causing poor cooling.
To start perform a complete defrost, allowing the unit to defrost overnight. This may temporarily fix problems related to defrost system and fix problems given by frozen damper fan.
If after defrosting the problem disappears to restart in few days or weeks, then it was not the temperature regulator but the defrost system. In that case test and eventually replace the thermostat located behind the freezer firewall.

Before replacing the refrigerator's temperature controls, you should do some basic troubleshooting to make sure the problem stems from a defective control and not some other problem. The most obvious thing to check is that the refrigerator is plugged in and receiving power from the outlet. If it is running, but not cooling, it could be due to dirty condenser coils or a defective door seal. Once the coils are clean and the door seal has been checked, you can be pretty confident that the problem is the temperature controls.
There are usually two control knobs, one that controls the temperature of the freezer and one that controls the refrigerator. Although they appear to be independent controls, it is important to understand that the cold air comes solely from the freezer area into the refrigerator compartment. The freezer control determines how much cold air the condenser produces while the refrigerator control adjusts the flow of cold air from the freezer to the refrigerator compartment. If there is no cold air on either side, it is probably the freezer control that is at fault. The procedure to replace the control switch is the same for the refrigerator control and for the freezer control.
it is still a good idea to test the control mechanism before replacing it. You will need a multitester and possibly needle-nose pliers and a screwdriver for the testing. First, unplug the refrigerator so you don't get shocked. Then, remove the temperature control's dial and/or housing. The dial will just pull straight off, but the housing may have screws holding it in place. After removing the housing, just let it hang by its wires. There should be two wires attached to the control. Label them before disconnecting so it is easier to put back together. Remove the wires by pulling on the slip-on connectors, not the wires themselves. Needle-nose pliers may be needed to remove these connectors from the terminals, especially if the refrigerator is old.
Set the ohms setting on your multitester to X1 and attach one probe to each terminal. Turn the temperature control to off or to the warmest setting if there is no off position. The multitester should give you a reading of infinity if the control is on off and a reading of near infinity if there is no off position. Then turn the control to the coldest setting and retest. Now, the multitester should give you a reading of zero. If both of these tests are not passed, the control needs to be replaced.
