The fridge stopped cooling but the freezer was OK. I defrosted and cleaned the fridge and freezer, and call the technician. Technician inspected my fridge and find that LOWER BOARD CONTROL is faulty. After hi left the opposite has happened .The fridge has started running too cold and freezing everything. After week of waiting for parts I did replace LOWER BOARD CONTROL that was suggested by a technician. Didn't change nothing, the fridge is running too cold and freezing everything. Im wondering if technician did something to the fridge to make it colder for the time being, or he did something wrong. I won't call him again but thats another story and I won't get in to it. I had most of fridge and freezer disassembled and the only thing I can think of is the little temperature sensor-thermostat behind the inside panel of the fridge. Any help will be appreciated
Please provide the model number for your fridge
Hi Scott the model number is Westinghouse BJ515V thanks for trying to help
I have looked up your model and I do not see anything that would cause this problem, unless somthing was hooked up incorrect. Sorry and good luck.
thanks Scott for trying to help. I will inform you if I get to the botom of this problem.Thanks again

DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.
If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.
The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.
If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.
If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.
Post your model number for more specific information.

You have to pull out the sensor from the board and test with tester, both sensor should read the resistance of 10,000 to 20,000 ohms. The reading that you show is very low it means that the thermistor is out of range and need replacement.
SOURCE: fan in the freezer stop working ater a while
The service manual gives the following explanation of your error code (Er FF): "Poor motor, hooking of wires to fan. Contact of structures to Fan. Snapping or short-circuit of L/wire (if there is no fan motor signal for more than 60 seconds in operation of fan motor)" So CoolTech is right!

IT IS THE DEFROST THERMO STAT REMOVE REAR COVER AND MELT ICE IT IS ROUND SILVER PART
SOURCE: No Cooling in the Fridge section, freezer is icing
unblock the ice or obstruction to the drain pipe from the freezer to the top of the compressor. make sure the little metal thing is over the heater element and hanging in the drain hole so it heats when the defrost element comes on.
Top of Form
If there is no cooling at all on the fridge section but the freezer works then it is confirmed that the compressor and gas pressure is OK. Now shut off the fridge and leave it powered off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if ice forms in the freezer then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
The blower fan also must work. if not there wont be cool air blown. If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
So try this test using a multi-meter on the defrost timer and the thermostat and make your observations so that we come to the solution.

Reaplacing temperature sensor-thermostat behind the inside panel of the fridge didn't make any different!!!
the fan usually stops working due to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature. May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
I would also suggest check ur thermistors which regulate the coldness features. and check and make sure ur air flow damper vent and knob are set right, not to high and not all the way open or closed?
I disagree with greg as the thermistor does make a differnece
