Why is my refrigerator working but my freezer isn't freezing?

When your residential refrigerator fresh food compartment maintains proper cold temperatures while the freezer section turns warm and fails to freeze items, the malfunction typically points to an issue with door sealing, ambient placement, or dual-evaporator controls. First, inspect the rubber magnetic door gaskets around the freezer perimeter for cracks, warping, or gaps that allow warm, humid room air to seep inside continuously. Second, if your refrigerator uses an electronic dual-evaporator system with separate cooling zones, a faulty temperature sensor or control board relay can prevent the freezer evaporator from running. You can troubleshoot door seals easily using the dollar bill test. You can verify that your repair is successful when replacing warped gaskets or resetting control boards restores sub-zero freezing temperatures inside the freezer compartment.
