Refrigerator Not Cooling
Check controls, door closure, loading and ventilation while protecting food and leaving sealed refrigeration parts alone.
Keep guards, panels and safety devices in place. Stop whenever the next action needs tools, live testing, disconnection or access beyond the owner's manual.
Checks you can safely make
- Protect food first
Keep doors closed and move perishable food to a working refrigerator or ice-filled cooler if the compartment has been above 40°F for an uncertain period.
- Verify settings and power
Confirm the interior light or display works and the control was not moved to Off or Cooling Off. Use the owner's manual for the recommended starting setting.
- Check door closure
Remove packages blocking the door, clean the gasket contact surface and use the paper test to find an obvious gap without adjusting hinges.
- Restore ventilation
Keep interior air vents clear and confirm the appliance has the installation clearances in its manual. Avoid packing food tightly against the back wall.
Common questions
How cold should a refrigerator be?
FDA food-safety guidance uses 40°F or below for the refrigerator. A separate appliance thermometer gives a more useful reading than the control number.
Can overfilling stop a refrigerator cooling evenly?
Yes. Packages can block internal vents and prevent cold air from circulating, even while the machine is running.
