In order to complete this job you will need the following tools:
Needle nose pliers
1/4″ nut driver
Ohm meter (Voltage Meter)
The first thing that you need to do , is unplug the refrigerator from its power source. The cold control is a thermostat that regulates the temperature inside of the refrigerator. Most cold controls are located refrigerator not the freezer. Although there are a few that are located in the freezer. This is more commonly found in older models of side by side models. When you have two controls in your refrigerator, the control that has the off position is the Cold Control. The other control operates a damper that allows the airflow from freezer to the refrigerator. Remove the control panel from the wall then you should be able to locate the cold control. The cold control will have two wires that are plugged into it. You will need to remove these two wires, and a long capillary sensor.
Note: This test is to be performed while the cold control is set to the ON position. Now put each of the Ohm meter leads onto each of the terminals on the control. If the control contacts are closed, there will be a zero reading on a digital voltage meter or on a standard voltage meter the needle will move to the right. If there is number one reading on the voltage meter if using a digital meter, this means the control contacts are open and the cold control is going to need to be replaced.
Note: This test is to be performed while the cold control is set to the OFF position. Now you need to put each of the Voltage meter leads on each of the terminals of the control. If the control contacts are closed, there will be a zero reading on the digital Voltage meter. If the control contacts are closed while in the OFF position, the cold control is bad and will need to be replaced.
We know this is only a general idea on how to test your refrigerator cold control, but it should give you the most important points to be able to complete the job.
