This year (some 3 years later, fridge went out again only this year it was the controller. After part was replaced it still wouldn't cool. Then I recalled from 2014, the need to thaw the freezer coils. Once this was done web were back in action!
Remember to check the freezer coils for frost/ice build up. It may require you to remove the remove the coil cover. Ice build up must be thawed and removed or the freezer won't still won't begin to freeze even after replacing thermostat, controller,v etc. You can expedite the thawing process by using a blow dryer to melt the ice buildup. Be careful using this method.
