When the freezer stays cold but the fridge section is warm, it's a very specific and common clue: the cold is being made fine, but it's not getting moved into the fridge. On most refrigerators both sections are cooled by one evaporator in the freezer, and a fan blows that cold air up into the fridge. So a warm-fridge/cold-freezer almost always points at airflow — a defrost problem or the fan. Here's the order a tech works it.
The #1 cause. If the auto-defrost system fails, frost builds up on the evaporator coils in the freezer and blocks the air path, so the fan can't push cold air into the fridge — freezer still cold, fridge warms up.
Check it: A quick test: unplug the fridge for 24 hours to let it fully defrost, then plug back in. If the fridge cools again for a day or two then warms up, that confirms a defrost fault (heater, sensor, or timer/control) — a tech repair.
The fan in the freezer that blows cold air into the fridge can fail. The freezer stays cold by conduction, but no air moves to the fridge. Often you'll hear no fan, or a clicking/buzzing.
Check it: Open the freezer and listen for the fan. Silence (or a fan that stops when you press the door switch by hand) points to a failed evaporator fan — an affordable, common part a tech replaces.
The vents that pass cold air into the fridge can be blocked by packed food or ice, choking the airflow.
Check it: Make sure food isn't packed against the vents (usually the upper back of the fridge section). Clear any ice you can see around the vents.
A stuck air damper (which meters cold air into the fridge) or a control problem can leave the fridge under-cooled while the freezer runs.
Check it: If the coils are clear and the fan runs, a tech checks the damper and control.
Usually repair — a defrost part or an evaporator fan is an affordable, common repair with flat labor, well below a new fridge. The 24-hour defrost test is free and often tells you (and the tech) exactly where to look.

Because both sections are usually cooled by one set of coils in the freezer, with a fan moving that cold air into the fridge. If the fridge is warm but the freezer's fine, the cold isn't getting moved — almost always frost blocking the coils (a defrost fault) or a failed evaporator fan. Both are common, affordable repairs.
Try the free test first: unplug the fridge for 24 hours to fully defrost, then restore power. If it cools again for a day or two then warms up, it's a defrost fault (heater/sensor/control). If you also hear no fan in the freezer, it's likely the evaporator fan. Both are tech repairs on affordable common parts.
Usually yes — a defrost part or evaporator fan is inexpensive and common, well below a new refrigerator. Your $50 Quick Check credits toward the repair, so you know the cost first.
