NO COLD AIR BLOWING TO REFRIGERATOR

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.

most likely bad evaporator fan motor located behind the wall in the freezer,when you open the freezer door you should hear the fan blowing in the freezer unless it's in defrost,if you don't hear it check it in 45 minutes if still no fan it's bad.

Not necessarily. There may be 2 compressors on the back of the unit, one for each side. If no,t the fan will blow cold air from the freezer's evaporator into the fridge side and will be between the two.

all the machine does is blow cold air from the freezer to the fridge side with a fan and then the air returns through air ducts,first off open the freezer door,you should hear the fan blowing,if not you could have a bad evap fan motor,next from the bottom up in the freezer,remove the second up from the bottom shelf or bin and put your hand on the back wall,is there like snow or ice on the wall?if so you have a defrost problem.let me know what you find and i can help you better

Hi Louis,

This is what has happened. Due to the door being opened for so long moisture which is naturally in the air has collected on your freezer coils. What you need to do is turn the whole thing off for at least 24 hours. Open the doors and put some towels around it to let the frost melt out.
All the air that gets cooled in your unit gets cooled by a fan that pulls air through those coils. Once the frost has melted out of them it should cool just fine.

unplugged the unit, kept the doors closed about 10 to 12 hours plugged back in and in about 2 hours started blowing cold air into freezer another 4 hours was blowing cold air into refrigerator and continuily got back to the themostat settings,about 1 day. no food was lost because the doors were closed still keeping it cold. i think the fan in the freezer was frozen with ice,but could access it, not the main fan in the back the unit by the compressor,that was running fine. so basically i defrosted the freezer fan by unplugging it. this is the 2nd time in 4 years ive done this, well it beats spending 1000-1500 dollars to replace it TRY IT I HOPE IT WORKS FOR YOU BEFORE YOU CALL FOR SERVICE,dave

Check to see if the fan is running in the frezzer side. This is called the evaperator fan and it blows the cold air from your evaperator to the ref side to cool it. If this is not running then your ref will not be cooling at all.

Listen for the fan motor to run. Open the freezer\ push the door switch with your finger \ listen for the fan that blows the cold air to the fridge. only the freezer side gets cold...fan blows cold to the fridge side. If the defrost timer has broken then ice may be blocking the flow of cold air to the fridge also. Only 2 things to check. Good Luck

Thre is a fan inside the freezer which circulates the cold air around both the fridge and the freezer compartments.
You should be able to feel cold air blowing around the inside, particularly at the top of the freezer.
If the defrost thermostat fails open, the internal fan (depending on freezer) will stop and this can be the cause of the freezer being warm at the top and no ice.
You say the bottom of the freezer is blowing cold, but are you sure its blowing, as it can feel like a cold blow. Of course the fan could have failed or may be the defrost heater itself.

Things to check
Check freezer...
for Frost build up and if Fan is blowing,
Check condenser...
To make sure clean, and the fan is blowing by compressor & IF it is running
Check Recirclating Vents in refrigerator... to make sure theres no blockage,

CONTROLS ...should be in the middle setting,
YOU CAN TRY turning FREEZER CONTROL
To A WARMER FREEZER SETTING
Allowing.. MORE AIR.. to refrigertor side
