What to Check Next on This Kenmore Refrigerator Kenmore Refrigerator Error F3: Use the code or symptom as the starting clue, then confirm what the refrigerator actually does before ordering parts. Unplug the refrigerator before touching wiring, fans, sensors, defrost parts, or control boards. Confirm both doors seal fully, the vents are open, the condenser area is clean, and temperatures have had time to stabilize. Check for frost buildup, fan noise, blocked air returns, warm spots, water-line issues, and loose sensor or harness connections. Note whether the symptom is warm fresh-food air, freezer thawing, ice-maker trouble, dispenser trouble, beeping, or display/control behavior. Replace a part only after the same symptom repeats and model-specific checks point to that part category. If the issue returns after these checks, match replacement parts to the complete Kenmore refrigerator model number from the appliance tag.
