Uick question. Freezer working great but not cold in fridge. Open the freezer door and the cold air blows up to the fridge compartment. Shut the freezer door and you get a warm fridge.. fan seems to be running excellent for cheap currys $##t
if you blow air up to fridge warm air has to return to freezer. dont do many fridges but i assume there has to be a return duct.
assume you have checked for ice blockages but though i would bring it up
