Also check the evaporator fan motor. This is usually located on the freezer side. If it's not turning then the fridge will not operate properly. You can hear it / or not on that side. Tear down the freezer side and look behind the panel door. You may have to remove the ice maker to properly get to it.
As a temporary fix you can spray it wil silicone lubricant to get it back going again. But like I said that is temporary. A full replacement is needed.
May as well since you tear it down already.
