Freezer workig fridge not cold checked fan wires intact when you open fridge door then close it you can hear fan operate for short time temp control light flashing will let you sit temp from warm to cold but after a few seconds temp light will switch off and when you press temp control again temp light comes on but temp will not stay as requested

Brand name and model would help but here is a guess. Most frost free refrigerators have the main cooling unit in the freezer area side. To get the fresh food side cold, there is a small fan in the freezer side that blows cold air to the fresh food side through a duct work or trap door. If that fan stops or fails for and reason, the first place you will notice the temp rise is in the fresh food section. See if you can hear the freezer fan running. You may need to push in the door switch for the freezer light to hear the fan because they sometimes run the fan wiring through the door switch. It may stop when door is opened.

check the damper vent door for proper opening and closing as if this door is frozen shut or broken and jammed it cant open to let cold air in from freezer it will be behind a plastic grille between the freezer and fridge compartments and you should hear a fan in there running to move cold air too

HI!!

The little fan inside the freezer is the one in charge of blowing cold air into the fridge area, the freezer control (thermostat), regulates how cold it should get, and the Refrigerator control regulates how much of this cold air goes to the fridge compartment. It is important to keep the door gasket clean at all times in order to have a good thight seal.

Check:

1.- That the freezer and fridge controls are set correctly, acording to manufacturers specs. (a common problem arises when by accident, the temp. controls are moved out of preset adjusment.

2.- That the fan is working and sounds strong, (If you keep the freezer door open for a couple of minutes, you should hear and see the motor kiking in.)

3.- Find the vent(s) in the fridge compartment and feel if cold air is coming thru when fan is working. If fan is working and blows no air, Take the freezer's back panel off, (4 hexhead screws) just enough to see inside and check if the evaporator (radiator looking component) is covered with ice, blocking the flow of air towards the fridge compartment, if it is, your defrost thermostat and-or timer are defective.

Your temp control for the fridge when you first start it, should be a bit higher than the one for the freezer. (the freezer should be in the low-middle range.) This control is nothing but a actuator for a door that controls the flow of air from the freezer. The bigger the number, the wider the door opens, and the colder the fridge gets.

Once the system is stable, let's say the next day, you can re-adjust your controls, (don't expect an inmediate change right away, change one digit a the time and check again next day) If you set your fridge too high and the freezer too low, the freezer may loose coldness and the problem would invert.

Good Luck!!!

check the damper door located between the freezer and refrigerator compartments(this lets in the cold air from the freezer) and make sure it opens and closes with your temp adjustment in the refrigerator compartment,sometimes they ice-up and are frozen in one position then take a hair dryer and defrost the 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.

The water could have been frozen in the door and melted when your fridge warmed up.


The lower hinge on each door may have a door closing cam. It raises the door up ¼ inch when opening and this assist in closing the door. If it’s wore out and doesn’t work the door may not seal and the gasket can be damaged. Watch the operation of the door to see if it rises up when opened.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

Is the fan that moves the air from the freezer to fridge running If there is a switch in cabinet somewhere the freezer door would contract it, with door open push in switch hear the fan both are good. Don't hear fan check evaporator or freezer fan and that switch it may be a duel switch open light closed fan run. Tricky there are light switches, when out light on or when switch is in its lights out

You might try removing and ohming out the door switches before you remove the fan motor. for fan motor operation the switch should read open on the NO to C and closed on NC to C with the switch out of the fridge. push and hold in the switch and the opposite readings should be observed IE closed on NO - C and open on NC - C. look closely at the switch for these letters.
If you have an electronic control system with an led or lcd display a magnetic switch may be employed and this would do both operations with a magnet close to the switch acuator.

First, I think it’s important to know that the Ref area has no cooling coils, it’s basically a box and the cold air in the freezer is blown over by a fan through a channel into the Ref side. This channel has a door which regulates how much cold air goes through. You probably have two control knobs in the Ref side, one controls the temp with numbers 1-9, 9 being the coldest. This temp control tells the compressor how long to run. The other control is for that little door and it may have letters A-E, E being the coldest. If you set it on E (coldest) then this will close that little door and keep most the cold air in the freezer.

Now, why is that cold air not getting up to the Ref side?
1. The little door is not open.
check your control setting. You should be able to feel air coming through the channel on the Ref side.

2. The fan in the freezer is not working.
You can hear this fan running when you open the freezer.

3. The coils on the freezer side are clogged with ice which won't let the fan circulate the air over to the Ref side.
This is a failure of the defrost system.
