Refrigerator running but not cooling: a practical checklist
A working light or a steady motor hum does not tell you whether food is safe. Work through the temperature question first, then separate likely causes without diagnosing a part from a web page.
Step 1: Check the actual temperature
Put a refrigerator thermometer inside the fresh-food compartment and record what it reads. FoodSafety.gov recommends maintaining the refrigerator at 40°F (4°C) or below and the freezer at 0°F (-18°C) or below. A digital control setting is not necessarily the same as the temperature of the food.
If perishable food has been above 40°F for more than two hours, use the federal food-safety chart rather than tasting it. During a power outage, keeping refrigerator and freezer doors closed preserves the cold for a limited time, but food condition still determines what is safe.
Step 2: Is the freezer working?
If the freezer is cold while the refrigerator compartment is warm, investigate whether packages are blocking internal vents and whether the fresh-food door closes firmly. Describe this split to the technician. Airflow and defrost problems are possibilities, not final diagnoses.
If both compartments are warm, record that separately. A qualified technician may need to test cooling, fan, electrical and control systems. Do not open refrigerant lines or electrical enclosures.
Step 3: Identify a repeatable pattern
- Only warm after shopping? Note whether many room-temperature items were loaded at once and whether the temperature later recovers.
- Food freezes on one shelf? Record shelf position, setting and visible blocked vents.
- Water below drawers? Photograph the location and check only accessible areas for spills.
- Ice maker not working? Note the water filter, supply setting and whether the rest of the freezer is keeping temperature.
Step 4: Prepare a useful repair request
Provide the brand and full model number, current thermometer reading, freezer condition, when the issue began, and any recent power interruption. This is enough to direct a diagnostic visit without asking you to guess whether the compressor, fan or sensor failed.
Step 5: Compare actual repair choices
Request an itemized estimate, including diagnostic fees, parts, labor and warranty. For an older refrigerator, use ENERGY STAR’s replacement energy tool as one input and compare the quote with an appropriately sized replacement. A high replacement price does not make an unsafe or unreliable repair reasonable.
