Bought this in 6/2005. My freezer is running fine my frig is warm the damper in the back is open, no air is coming out, hot or cold. the frig is clean underneath, no dust or dirt. I shut it off for an 1 1/2 to see if there was any ice build up. About a month agao my water was not working so I turned down the frig and it started to work. it still seamed to be cold enough. I thought nothing of it. could this be a poroblem woith the thermostat and whee is this and is it easy to change? I am pretty mechanical.

A refrigerator temperature problem like yours is likely due to one of the following issues. Open the freezer door and listen for the freezer fan, you might have to close the door/light switch to activate the fan. There is a vent at the top of the back wall of freezer, as well as a vent at the top back wall of the fresh food section. Wet your finger and place it in front of either vent and feel for cold air flow. If you dont feel any air flow in the fridge and the freezer fan is running, you will likely have a defrost problem, either the heater, the bi metal t stat, or the defrost control have failed. Any of these will result in frost on freezer back wall. YOu may also have a problem with the damper door in the fridge, again, top back wall, not opening, or on the rare occasion I have seen a slice of wrapped cheese on the floor behind the fresh food crispers covering the warm air return vent to the fridge.
it could be a defective damper vent door,( frozen shut from condensation) between the freezer and refrigerator,the motor that opens and closes this door,or a thermistor in the refrigerator that signals the control board in the rear of the unit to operate the damper vent door motor to open and close this door
The fridge gets its cold air from the freezer through a vent(damper)
between the freezer and fridge.The fan in the freezer blows air through it.
Make sure this fan is running. You may have to hold the door switch in for it
to run. There is a flap you adjust with
the fridge temp. control. Make sure it's opening and closing when you adjust
the fridge temp. The problem could be the electronic control if
you have one or the mechanical linkages.
You will be able to hear it when you open the freezer door and hold the door switch in.It is located behind the rear panel inside the freezer. The fan should be running when the compressor is running. If it is running make sure the damper(vent) to the fridge side is not blocked by ice and that the damper door is open.
You must check the evaporator fan motor in the freezer.
Is it running?
You may need to push the door switch with the freezer door open for fan to run with drawer open.
Next check the damper in the fresh food section.
Is it open?
Air circulating through?
If not, replace your damper control and thermistor.
If you are sure the fan in the freezer is running and you don't feel any air flow out of the top middle vent inside the fridge section, then the damper motor must be bad. The damper motor is behind that vent cover inside the fridge section.
This comes with a 1 yr warranty from date of purchase. Look and see if there is a thick frost buildup on the back panel in the freezer section. If no frost, shut the freezer door and feel for air flow out of the top middle vent in the fridge section. I would remove that vent cover to make sure the damper is open. If the damper is closed push it open then feel for air flow. If no air flow is detected then the evaporator fan motor is bad which is a very commom problem on this model, in fact the most common problem. If the damper is shut and when you hold it open you do feel air flow then the damper is bad. Let me know what you find.
Is your fan blowing in the freezer?
Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
There are 2 possible problems. One is the defrost cycle is not working properly this is usually indicated by a large amount of frost on the back freezer panel. If so, the circuit will have to be repaired and the evaperator thawed to remove the ice build up. The other is the fresh food damper is not working properly this is behind the "lump" in the back of the fridge compartment above the top shelf, remove the louver panel to see if it is open or closed. closed will be warm open should be cold.
The water dispenser reservoir is probably frozen due to poor air circulation.
