My freezer works perfectly but my refrigerator won't stay cold. My milk sours and I have the setting turned to the highest. HELP:confused:

Look for frost on the back inside the freezer compartment. If frost is there it could be your defrost system is having a problem.

TINYTINA - #1- CHECK to make sure the fan in the back of the freezer is runs:::
#2 Take a shop vac. Or the vacumn cleaner ,use a plastic wond so not to cause a shiock, and be careful not to tear up anything under neath; This needs to be done at least every 3 months;; the coils under neath get really covered with dust, fuzz, ECT. And the freeon can not cool back down before it gets back to the compressor, causeing the fridg to run warmer. ::: #3 Check to make sure the fan in the back under the fridg. Also runs, ;;;
#4- THe thermostat could also be the cause , you will have to get a appliance repairman to check it out for you though ;;; Have a HAPPY NEW YEAR AND GOD BLESS:: I HOPE WHAT I SAID HELPS YOU OUT :: F.B.E.
