Hi, Fridge has developed an intermittent issue with temp control. At times the freezer temp is way to cold. When set at normal mid-range setting it can be as cold as -20F. During these times the refrigerator section is also below normal..below 32F in the bottom sections. The temp difference between the freezer and refrigerator seems about right so I don't think it's a damper problem. My guess is a thermostat (thermistor??) problem. Please give short explanation of function of temp control and your suggestion of problem. How to test? I saw a 2.7K ohm @ room temp spec in another answer, is that for this thermistor? Thanks

ANSWER Pete, You will want to check the thermistors of the unit as this may be a bad thermistor 2188819. You can test the thermistors by removing from unit and letting them warm to room temp. At 77 degrees the resistance should be 2.7K ohms. If the thermistors are not reading the proper resistance then they are defective. If the thermistors check ok then the control 8201527is faulty and would need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
