Refrigerator will not cool - Freezer is ice cold ?
	
	
		My Whirlpool upright Refrigerator (on top) will not cool at all.  
Frig is currently 65 deg F and will not cool.
There does not seem to be any circulation in the refrigerator.
There is a small vent on the bottom (floor) in the frig under the vegetable drawers 
And there is the temperature selection unit box on the back wall- up high- 
Which has vents on it-   and NO air is moving near either of them.  
The Freezer (on bottom) is fine.  Ice cold.
The freezer is packed so I will look around and see if there is anything that might be blocked down there.
There was a small bit of ice (and frost) on the inside of the Freezer door.  
I will remove most of the freezer contents and see where air moves down there.  
I pulled the unit out from the wall- removed back cover(s) -  fan is fine and working, 
Compressor is running and warm.  
I removed the 'cover' on the front at the very bottom and found a ton of dust blocking and covering all the coils and everything else   - so I did a thorough 'dusting' w/ compressed air.
Dusted everything- front and back.   
Still-  Refrigerator will not cool.   
Other questions / answers here said refrigerator will cool faster than freezer (which of course is working fine) 
Biggest problem- is repair guys can not come till at least Monday (today being Thursday) 
And then might have to order and wait for parts.  
Would be great to troubleshoot and find a small fixable problem (yeaaahh Me !) OR
Troubleshoot and find which part is needs- so I can order it- or drive 
Somewhere to get it ! 
Puzzled? -  
I can not understand why the Refrigerator will not cool but the Freezer will - ? 
Thank you  the Ironman-
