I have a side by side Frigidaire model KSSS42QDX02 the freezer isn't freezing and the refrigerator won"t cool without the freezer being turned on...HELP!

the damper vent door between the freezer and refrigerator isn't opening to let cold air into the refrigerator compartment from the freezer side,its in the upper left corner in the refrigerator behind a grille,if its closed you wont feel cold air flowing in from the freezer sometimes you can shine a light in this area and look in the other compartment and if no light then the doors shut and this is why its not cooling the refrigerator

The temperature control thermostat, alson known as the colds control thermostat has gone bad and basically isn't converting electrical/temperature signal properly and needs to be replaced

Its defrost problem, the freezer should cool, then freeze, then defrost cycle should start. In your case freezer is cooling, then freezing, but its not defrosting. That's why fridge section is not cooling.-------

That is the classic symptoms of a defrost system failure. Suggest you look behind the rear panel on the inside of your freezer and see if it is iced up. If it is then it is a defrost problem which could be the defrost heater, defrost thermostat or defrost timer. If it isn't iced up, then check to make sure the fan is operating. If it isn't then it won't push cold air out of the freezer into the refrigerator section.

Your defrost circuit is made up of a defrost heater, defrost thermostat and a defrost timer (generally, but will depend on make and model). They are relatively straight forward to troubleshoot and replace, and not that expensive.

Suggest you go to www.searspartdirect.com and plug in the model number of your frigerator and look up the parts you need to get an idea of how much they are. NOTE: Sears isn't the cheapest place to buy the parts, but they use the real part number for further research.
